This is necessary +because at cold start, the CPU is executing code in lower +memory which is the same area that is bank switched. + +Phase 1 of booting copies phase 2 code to upper memory +and jumps to it to continue the boot process. + +Phase 2 of booting manages the setup of the RAM page +banks as needed. In the case of a hardware startup, +phase 2 just copies the code from ROM page 1 into RAM +page 1 and executes the loader. In the case of an +application startup (.com file used to load a new +copy of the system), phase 2 copies the first 32KB +of the application memory space into RAM page 1 +and executes the loader. + +See 'bootrom.asm' for the implementation of the ROM +(hardware) startup. See 'bootapp' for the implementation +of the application based startup. + +General Design Strategy +----------------------- + +The design goal is to locate as much of the hardware +dependent code as possible out of normal 64KB CP/M +address space and into a bank switched area of memory. +As calls are made to HBIOS, the lower 32KB of memory +is switched to 'bank 1' which contains all of the +driver code. The operating system is unaware this +has occurred. As control is returned to the Operating +System, the lower 32KB of memory is switched back to +normal 'bank 0'. + +HBIOS implements a small 'shim' (proxy) that lives in the +upper page (256 bytes) of RAM. This shim is responsible +for handling the HBIOS call invocations. It is the +target of 'RST 08' and will simply switch in RAM +bank 1 into lower RAM forward the call to the lower +memory, then switch lower memory back to RAM bank 0 +on return. + +In the case of CP/M and ZSDOS, CBIOS is built to +utilize HBIOS for most of the work. CBIOS contains +the required CP/M data structures such as DPH and DPB +and is responsible for translating and forwarding work +to HBIOS as needed. + +Notes +----- + +1. Size of ROM disk and RAM disk will necessarily be +decreased by 32KB each. User will need to make sure +that RAM disk is reformatted (CLRDIR). \ No newline at end of file diff --git a/trunk/Doc/Build.txt b/trunk/Doc/Build.txt new file mode 100644 index 00000000..c8ff39b8 --- /dev/null +++ b/trunk/Doc/Build.txt @@ -0,0 +1,331 @@ +Building a Custom ROM +--------------------- + +At present, the build environment assumes you are running +a current version of Microsoft Windows (either 32-bit or +64-bit). + +If you are using Linux, David Giles has contributed a Linux +makefile that should work for you. Please read the +LinuxBuild.txt file for more information. + +All required tools are included in the distribution. You +should not need anything other than what comes as part of +Windows or as part of the distribution. + +In summary, the process involves the 4 steps below: + + 1) Create/update configuration file + + 2) Update/Add/Delete any files you want incorporated in + the ROM Disk + + 3) Run the build script (or makefile if you prefer) and + confirm there are no errors. + + 4) Burn the resultant ROM image and try it. + +The process is really very simple. In fact, you can +essentially skip steps 1 & 2 if yoiu want to try simply +building one of the existing configurations. + +Each of the 4 steps above is described in more detail +below. + +1. Create/Update Configuration File +----------------------------------- + +The settings for a build are primarily controled by +a configuration file that is included in the build +process. In order to customize your settings, you +need to modify an existing configuration file or +create your own. + +If you look in the Source directory, you will see +a series of files named config_xxxxxx.asm. Each of +them corresponds to one of the standard configurations +listed in the ROMList.txt file. + +You have two choices. You can simply modify the existing +configuration file that is closest to your situation, or +you can copy it to a new config_xxxxx.asm file and modify +that. I recommend that you copy one to your own name so +that you will always have the unmodified standard configuration +files left in place. So, for example, you could just +copy config_zeta.asm to config_wayne.asm. You MUST +name your config file as congig_xxxxxx.asm. The xxxx's +can be whatever you want, but the rest must be exactly +as indicated. + +The config files are simply text files with various +settings. Open your target config file with your +favorite text editor and modify the settings as desired. + +Unfortunately, I have not yet documented each of the +settings in detail; that will be a separate document +provided in the future. However, there are comments +in the config file that will probably be sufficient +for the most part. + +2. Update/Add/Delete ROM Disk Files +----------------------------------- + +The files that are included on the ROM Disk of your +ROM are copied from a set of directories during the +build process. This allows you to have complete +flexibility over the files you want included in your +ROM. + +If you look at the RomDsk directory, you will see +a variety of subdirectories. These subdirectories +contain the files that will be included in the +ROM disk. The build process will determine +which subdirectories to include files from based +on the following rules: + +First, all files from either std_512 or std_1024 will +be incuded depending on on the size of the ROM you +are building. If you are building a 512KB ROM, then +all the files from std_512KB will be included. If you +are building a 1MB ROM, then all the files from std_1024KB +will be included. Essentialy, the files in std_1204KB are +a superset of the ones in std_512KB because there is more +space available for the ROM drive. + +Second, all files from the directory that corresponds to +your configuration file will be included. If you build +the "zeta" configuration, all files in cfg_zeta will +be added. Note that these files will be in addition +to the files from the std_XXXKB directory. + +If you created your own config file (like config_wayne.asm +described above), you MUST create a subdirectory within +the RomDsk directory and populate it with the files +you want added. Normally, you would include the +files from the original standard config. So, if +you created config_wayne.asm from config_zeta.asm, +then you would create a subdirectory in RomDsk called +cfg_wayne and copy all the files from cfg_zeta to +cfg_wayne. + +Finally, you will notice another subdirectory called +RomApps. This is directory is used to place a set of +RomWBW apps provided by Douglas Goodall. The driectory +will be populated automatically and the files will be +included automatically. + +3. Run the Build Process +------------------------ + +NOTE: The process described here is the more commonly +used build script. If you wish to use a makefile +instead, refer to the comments in the makefile in +the Source directory as an alternative to the +process described here. + +The build involves running a command at the command +prompt. From a Command Prompt window, you will need +to change to the high level directory for the build. +Normally, you would be changing to the RomWBW directory +unless you renamed it. + +To run the build and be prompted for required information, +just enter "Build". You will be prompted for the information +described below and the build should run. If an error is +encountered, the build should stop and display an error +in red text. + +If you immediately receive the error "the execution of +scripts is disabled on this system", then you will need to +change the PowerShell Execution-Polcy to "Unrestricted". +To do this, you need to right-click on FixPowerShell.cmd and +choose "Run as Administrator" to make the change. If is +critical that you right-click and use "Run as Administrator" +or the change will not work (you will get an error +indicating "Access to the registry denied" if you fail to +use "Run as Administrator". + +The build script will prompt you for the following information +which you will need to provide (don't worry, it is simple): + +Configuration: + +Respond with the name of the configuration you wish to build. +A list of all available configurations is displayed for your +convenience. For example, if you are buidling the provided +zeta configuration, just enter "zeta". If you have created a +custom configuration as described above, you would enter +"wayne". + +ROM Size [512|1024]: + +Respond with either "512" for a 512KB ROM build or "1024" for a +1MB ROM build. Only the two choices are possible at this time. +It is important that you choose a ROM size that is no larger than +the szie of the ROM you will ultimately be burning. This is +dependant on your hardware. + +CPU Type Z[80|180]: + +Respond with "80" if the ROM is for Z80 hardware such as the +N8VEM Z80 SBC or for Zeta. Respond with "180" if the ROM is +for Z180 based hardware such as the N8. + +System [CPM|ZSYS]: + +Respond with the type of system you wish to create. If you are +not sure which you want, you should enter "CPM". Refer to the +ReadMe.txt file for more informatino on the difference between +the two system types. + +At this point the build should run and you will see output related +to the assembler runs and somem utility invocations. Just review +the output for any obvioius errors. Normally, all errors will +cause the build to stop immediately and display an error message +in red. + +You will see from lines in the output indicating the amount of +space variouis components have taken. You should check these +to make sure you do not see any negative numbers which would +indicate that you have included too many features/drivers for +the available memory space. Here are examples of the lines +showing the space used: + + DATA space remaining: 39 bytes. + BOOT LOADER space remaining: 3503 bytes. + CBIOS space remaining: 161 bytes. + DBGMON space remaining: 860 bytes. + ROMX space remaining: 8191 bytes. + BOOT LOADER space remaining: 3503 bytes. + +4. Deploy the ROM +----------------- + +If you look in the Output directory. You should find the following files: + + .rom - binary ROM image to burn to EEPROM + .sys - system image that can be written to the start of a + disk to enable boot from disk functionality + .com - executable version of the system image that can be + copied via xmodem to a running system to test + the build. + +The actual ROM image is the file ending in .rom. It should be exactly +512KB or 1MB depending on the ROM size you chose. Simply burn the .rom +image to your ROM and install it in your hardware. + +Specifying Build Options on Command Line +---------------------------------------- + +If you don't want to be prompted for the options to the "Build" +command, you can specify the options right on the command line. + +For example: + + Build zeta 512 80 CPM + +In this case, you will not be prompted. This is useful if you +wish to automate your build process. + +Example Build Run +----------------- + +C:\Users\WWarthen\N8VEM\Build\RomWBW>build +Configurations available: + > n8 + > n8vem + > n8vem_dide + > n8vem_diskio + > n8vem_diskio3 + > n8vem_ppide + > n8vem_vdu + > n8vem_vdux + > simh + > zeta +Configuration: zeta +ROM Size [512|1024]: 512 +CPU Type Z[80|180]: 80 +System [CPM|ZSYS]: CPM + +Building zeta: 512KB ROM configuration zeta for Z80... + +tasm -t80 -b -g3 -fFF ccpb03.asm cp.bin +TASM Z80 Assembler.

Note that JC110508 included +the fix for DPB in CBIOS for large ROM drive. Specifically, EXM_5 +was changed from 1 -> 0 (as it should have been). + +1) Fixed the stack location in loader-b.asm. LOADER.COM was not working +for me without this change. + +2) Fixed the size of the ccp+bdos+cbios in bloader.asm and loader-b.asm. +It was too small before and would be a potential problem depending on +how many of the optional features were enabled. + +3) Fixed the "MON" command in cpm. It was jumping to an old/bad location. +I modified the way it works a bit to handle the situation where it can +become overlaid. There is now a routine in cbios.asm to reload it and +branch to the warm start location. The address of the cbios routine is +now saved in the cbios scratch area of zero page (40H) so that ccp does +not need to have a hard coded location in it. + +4) Corrected ROM memory layout a bit. Small ROM drive was starting at the +wrong location (4800H). It should have been 5000H. So, I gave the loader +2K more space. Required modifications to bloader and cbios. Renamed +'romdsk.dsk' to 'romdsk.dat' to help alert folks to the fact that this is +a different image and allows "clean" to remove anything with a suffix +of '.img'. + +5) Changed bloader to allow selection of DSKY or UART monitor using JP2. +A single ROM can now be dynamically configured to start via DSKY or UART. + +6) Fixed small ROM disk DPB in cbios. Changed DSM_6 from 31 -> 11. Based +on blocksize of 1024 and the fact that it is now a 12K area, 11 is the +correct value. Also fixed EXM_6 from 1 -> 0 (per DRI spec). + +7) Moved startup message from warm boot to cold boot. Also moved VDU init +to cold boot -- seems appropriate, but I have no way to test this yet... + +8) More DPB tweaks. I have reviewed the floppy and RAM/ROM DPB's. I have +not looked at ATAPI or IDE. May still be problems in those. + +9) Complete overhaul of build scripts. Reworked makefile to be compatible +with the make utility from gcc and created MakeRom.cmd to invoke the gcc +make utility. Created a PowerShell script as an alternative way to create +ROM (BuildRom.ps1) and created BuildRom.cmd to invoke it. Final ROM +image is now called rom.img -- made more sense to me, but I have no +compelling justification for changing that. BuildRom2.bat is still +there and I think it works. + +10) Played with the startup message in cbios a bit. Extracted the "build" +id and moved it to the top of the file. My intent is to make it easy to +update. Ultimately, I wold prefer that it be updated with the current +date of the build as part of the build scripts, but still debating how +best to accomplish that. + +11) Related to #10, I have extracted the 3rd party build tools into sibling +directories. So, for example, tasm is now found at tasm32. This makes it +very easy to update the 3rd party tools and to clearly differentiate the +3rd party tool files. All build script have been updated as needed. + +12) Removed ALL enable interrupt (EI) instructions in CBIOS. By leaving +interrupts disabled the BIOS will now start OK even if some vagrant +hardware is asserting an interrupt (DISKIO). Seems like this is better +anyway -- general idea is that we only enable interupts precisely +when desired for very specific controled purposes since there is no +concept of interrupt dispatching available. \ No newline at end of file diff --git a/trunk/Doc/DesignNotes-1.4.txt b/trunk/Doc/DesignNotes-1.4.txt new file mode 100644 index 00000000..155e511e --- /dev/null +++ b/trunk/Doc/DesignNotes-1.4.txt @@ -0,0 +1,16 @@ +Design Notes for 1.4 - + +12/25/2011 DWG - Logical Unit enhancement for block drivers + +The previous version implemented Logical Unit functionality +by poking an offset word into a private data structure in +PPIDE_DATA.ASM. + +In order to make the Logical Unit functionality more generic, +Wayne suggested adding the appropriate data items to the end +of the Disk Parameter Header data structure (because there is +one each for each drive). + +The added items consist of a Logical Unit enhancement signature +which is two bytes "LU", and several subsequent items including +a default slice number and status. diff --git a/trunk/Doc/FdTst.txt b/trunk/Doc/FdTst.txt new file mode 100644 index 00000000..fefec401 --- /dev/null +++ b/trunk/Doc/FdTst.txt @@ -0,0 +1,429 @@ +================================================================ +FDTST v3.1 for N8VEM DISKIO / DISKIO V3 / ZETA / DIDE / N8 +================================================================ + +Updated JuLY 1, 2012 +by Wayne Warthen (wwarthen@gmail.com) + +Application to test the hardware functionality of the Floppy Disk +Controller (FDC) on the ECB DISK I/O, DISK I/O V3, ZETA SBC, +Dual IDE w/ Floppy, or N8 board. + +The intent is to provide a testbed that allows direct testing +of all possible media types and modes of access. The application +supports read, write, and format by sector, track, and disk as +well as a random read/write test. + +The application supports access modes of polling, interrupt, +INT/WAIT, and DRQ/WAIT. At present, it supports 3.5" media at DD (720KB) and +HD (1.44MB) capacities. It also now supports 5.25" media (720KB and 1.2MB) +and 8" media (1.11MB) as well. Additonal media will be added when I have +time and access to required hardware. Not all modes are supported +on all platforms and some modes are experimental in all cases. + +In many ways this application is merely reinventing the wheel and +performs functionality similer to existing applications, but I have +not seen any other applications for DISK I/O that provide this range +of functionality. + +While the application is now almost entirely new code, I would like to +acknowledge that much was derived from the previous work of Andrew Lynch +and Dan Werner. I also want to credit Sergio Gimenez with testing the 5.25" +drive support and Jim Harre with testing the 8" drive support. Thanks! + +General Usage +------------- + +In general, usage is self explanatory. The main menu allows you to set +the unit, media, and mode to test. These settings MUST match your +situation. Read, write, format, and verify functions are provided. A sub-menu +will allow you to choose sector, track, disk, or random tests. + +The verify function requires a little explanation. It will take the contents +of the buffer, save it, and compare it to the selected sectors. So, you +must ensure that the sectors to be verified already have been written +with the same pattern as the buffer contains. I typically init the buffer +to a pattern, write the pattern to the entire disk, then verify the entire +disk. + +Another submenu is provided for FDC commands. This sub-menu allows you to +send low-level commands directly to FDC. You MUST know what you are doing +to use this sub-menu. For example, in order to read a sector using this +sub-menu, you will need to perform specify, seek, sense int, and read +commands specifying correct values (nothing is value checked in this menu). + +Required Hardware/BIOS +---------------------- + +Of course, the starting point is one of the support hardware platforms. +You need to start with either an N8VEM SBC, backplane, and ECB DISK I/O +card or a Zeta SBC. Additionally, a floppy drive connected via an +appropriate cable: + +DISKIO - no twist in cable, drive unit 0/1 must be selected by jumper on drive +ZETA - cable with twist, unit 0 after twist, unit 1 before twist +DIDE/N8 - cable with twist, unit 0 before twist, unit 1 after twist + + +It is preferable that the BIOS you use does not have DISK I/O support +enabled since the application assumes it has complete control of the +DISK I/O hardware. + +The DISK I/O should be jumpered as follows: + +J1: depends on use of interrupt modes (see interrupt modes below) +J2: pins 1-2, & 3-4 jumpered +J3: hardware dependent timing for DMA mode (see DMA modes below) +J4: pins 2-3 jumpered +J5: off +J6: pins 2-3 jumpered +J7: pins 2-3 jumpered +J8: off +J9: off +J10: off +J11: off +J12: off + +Note that J1 can be left on even when not using interrupt modes. As +long as the BIOS is OK with it, that is fine. Note also that J3 is +only relevant for DMA modes, but also can be left in place when +using other modes. + +The DISK I/O V3 should be jumpered at the default settings: + +JP2: 3-4 +JP3: 1-2 for int mode support, otherwise no jumper +JP4: 1-2, 3-4 +JP5: 1-2 +JP6: 1-2 +JP7: 1-2, 3-4 + +Zeta does not have any relevant jumper settings. + +DIDE should be jumpered as follows: + +K3 (DT/R or /RD): /RD +P5 (bd ID): 1-2, 3-4 (for $20-$3F port range) + +There are no specific N8 jumper settings, but the default +I/O range starting at $80 is assumed in the published code. + + +Modes of Operation +------------------ + +You can select the following test modes. Please refer to the chart +that follows to determine which modes should work with combinations +of Z80 CPU speed and media format. + +Polling: Traditional polled input/output. Works well and very reliable +including timeouts and good error recovery. Also, the slowest performance +which precludes it from being used with 1.44MB floppy on a 4MHz Z80. +This is definitely the mode you want to get working before any others. +It does not require J1 (interrupt enable) on DISK I/O and does not care about +the setting of J3. + +Interrupt: Input/output is interrupt driven. Works pretty well, but +is not able to recover from some errors. For example, if there is +no disk in the drive, this mode will just hang until a disk is inserted. +This mode REQUIRES that interrupts be enabled on the DISK I/O via +jumper at J1. On Zeta it requires the INT/NMI jumper be set for +INT. Mode not supported on DIDE or N8. Some BIOS variants will not +handle interrupts during boot. + +Fast Interrupt: As above, but sacrifices additional reliability for +faster operation. This mode will allow a 1.44MB floppy to work +with a 4MHz Z80 CPU. However, if any errors occur (even a transient +read error which is not unusual), this mode will hang. As above +you MUST have the appropriate jumpers for DISKIO and Zeta. DIDE +does not support this mode. + +INT/WAIT: Same as Fast Interrupt, but uses CPU wait instead of +actual interrupt. Subject to all the same issues as Fast +Interrupt, but does not need J1 shorted. J3 is irrelevant. +This mode is available on only on DISKIO (and not DISKIO V3). + +DRQ/WAIT: Uses pseudo DMA to handle input/output. Does not require that +interrupts (J1) be enabled on the DISK I/O. However, it is subject to +all of the same reliability issues as "Fast Interrupt". This +mode is known to not work on N8VEM DISKIO!!! It is included +for testing only. It is dependent on setting of J3. This +mode is NOT available on Zeta, DIDE, N8, or DISKIO V3. + +The chart below attempts to describe the combinations that +work for me. By far, the most reliable mode is Polling, +but it requires 8MHz CPU for HD disks. + +DRQ/WAIT --------------------------------+ +INT/WAIT -----------------------------+ | +Fast Interrupt --------------------+ | | +Interrupt ----------------------+ | | | +Polling ---------------------+ | | | | + | | | | | +CPU Speed --------------+ | | | | | + | | | | | | + | | | | | | + +3.5" DD (720K) ------ 4MHz Y Y Y Y X + 8MHz+ Y Y Y Y X + +3.5" HD (1.44M) ----- 4MHz N N Y Y X + 8MHz+ Y Y Y Y X + +5.25" DD (360K) ----- 4MHz Y Y Y Y X + 8MHz+ Y Y Y Y X + +5.25" HD (1.2M) ----- 4MHz N N Y Y X + 8MHz+ Y Y Y Y X + +8" DD (1.11M) ------- 4MHz N N Y Y X + 8MHz+ Y Y Y Y X + +Y = Yes, works +N = No, does not work +X = Experimental, probably won't work + +Tracing +------- + +Command/result activity to/from the FDC will be written out +if the trace setting is changed from '00' to '01' in setup. +Additionally, if a command failure is detected on any +command, that specific comand and results are written +regardless of the trace setting. + +The format of the line written is: +: --> [] + +For example, this is the output of a normal read operation: +READ: 46 01 00 00 01 02 09 1B FF --> 01 00 00 00 00 02 02 [OK] + +Please refer to the i8272 data sheet for information on the +command and result bytes. + +Note that the sense interrupt command can return a non-OK +result. This is completely normal in some cases. It is +necessary to "poll" the drive for seek status using +sense interrupt. If there is nothing to report, then +the result will be INVALID COMMAND. Additionally, +during a recalibrate operation, it may be necessary to +issue the command twice because the command will only step +the drive 77 times looking for track 0, but the head may be +up to 80 tracks away. In this case, the first recalibrate +fails, but the second should succeed. Here is what this +would look like if trace is turned on: + +RECALIBRATE: 07 01 --> [OK] +SENSE INTERRUPT: 08 --> 80 [INVALID COMMAND] + ... + ... + ... +SENSE INTERRUPT: 08 --> 80 [INVALID COMMAND] +SENSE INTERRUPT: 08 --> 71 00 [ABNORMAL TERMINATION] +RECALIBRATE: 07 01 --> [OK] +SENSE INTERRUPT: 08 --> 21 00 [OK] + +Another example is when the FDC has just been reset. In +this case, you will see up to 4 disk change errors. Again +these are not a real problem and to be expected. + +When tracing is turned off, the application tries to be +intelligent about error reporting. The specific errors +from sense interrupt documented above will be suppressed +because they are not a real problem. All other +errors will be displayed. + +Error Handling +-------------- + +There is no automated error retry logic. This is very +intentional since the point is to expose the controller +and drive activity. Any error detected will result in +a prompt to abort, retry, or continue. Note that some +number of errors is considered normal for this +technology. An occasional error would not necessarily +be considered a problem. + +CPU Speed +--------- + +I distribute the binary version of the application optimized for +20MHz CPUs. There is a configuration variable called CPUFREQ +at the top of the source file. Ideally, you should build +with that set appropriately. However, I have found that the +default build setting of 20MHz seems to work for 4-20MHz CPUs. + +Interleave +---------- + +The format command now allows the specification of a sector +interleave. It is almost always the case that the optimal +interleave will be 2 (meaning 2:1). + +360K Media +---------- + +The 360K media definition should work well for true 360K +drives. However, it will generally not work +with 1.2M drives. This is because these drives spin at 360RPM +instead of the 300RPM speed of true 360K drives. Additionally, +1.2M drives are 80 tracks and 360K drives are 40 tracks and, so +far, there is no mechanism in FDTST to "double step" as a way +to use 40 track media in 80 track drives. + +With this said, it is possible to configure some 1.2M 5.25" drives +to automatically spin down to 300RPM based on a density select +signal (DENSEL). This signal is asserted by FDTST for 360K +media, so IF you have configured your drive to react to this +signal correctly, you will be able to use the 360K media defintion. +Most 1.2M 5.25" drives are NOT configured this way by default. +TEAC drives are generally easy to modify and have been tested by +the author and do work in this manner. Note that this does not +address the issue of double stepping above; you will just be +using the first 40 of 80 tracks. + +Support +------- + +I am happy to answer questions as fast and well as I am able. +Best contact is wwarthen@gmail.com or post something on the +N8VEM Google Group https://groups.google.com/forum/#!forum/n8vem. + +Changes +------- + +WW 8/12/2011 + +Removed call to pulse TC in the FDC initialization +after determining that it periodically caused the FDC to write +bad sectors. I am mystified by this, but definitely found it +to be true. Will revisit at some point -- probably a timing +issue between puslsing TC and whatever happens next. + +Non-DMA mode was being set incorrectly for FAST-DMA mode. +It was set for non-DMA even though we were doing DMA. It is +interesting that it worked fine anyway. Fixed it anyway. + +DIO_SETMEDIA was not clearing DCD_DSKRDY as it should. Fixed. + +WW 8/26/2011: v1.1 + +Added support for Zeta. Note that INT/WAIT and DRQ/WAIT are +not available on Zeta. Note that Zeta provides the ability +to perform a reset of the FDC independent of a full CPU +reset. This is VERY useful and the FDC is reset anytime +a drive reset is required. + +Added INT/WAIT support. + +WW 8/28/2011: V1.2 + +All changes in this version are Zeta specific. Fixed FDC reset +logic and motor status display for Zeta (code from Sergey). + +Modified Zeta disk change display to include it in the +command output line. This makes more sense because a command +must be issued to select the desired drive first. You can +use the SENSE INT command id you want to check the disk +change value at any time. It will also be displayed with +any other command output display. + +WW 9/1/2011: V1.3 + +Added CPUFREQ configuration setting to tune +delays based on cpu speed. The build app +is set for 8MHz which also seems to work well +for 4MHz CPU's. Faster CPU speeds will +probably require tuning this setting. + +WW 9/5/2011: V1.4 + +Changed the polling execution routines to utilize CPUFREQ +variable to optimize timeout counter. Most importantly, +this should allow the use of faster CPUs (like 20MHz). + +WW 9/19/2011: V1.5 + +Zeta changes only. Added a call to FDC RESET after any +command failure. This solves an issue where the drive +remains selected if a command error occurs. Also +added FDC RESET to FDC CONTROL menu. + +WW 10/7/2011: V2.0 + +Added support for DIDE. Only supports polling IO and it +does not appear any other modes are possible given the +hardware constraints. + +WW 10/13/2011: V2.1 + +Modified to support N8.

I strongly recommend reviewing the zsdos.pdf file in the Doc directory. + +The starting point was the general public release of ZSDOS that is generally available. The first line of the README file is "ZSDOS-GP. General Public Release of the ZSDOS 1.x Operating System." + +The actual ZSDOS source code was minimally modified to achieve TASM assembler compatibility. In order to minimize the number of changes to the source, I created a "wrapper" that defines a bunch of helper macros to improve compatibility. The wrapper uses a #INCLUDE to imbed the actual ZSDOS source. + +ZSDOS is really two things. ZSDOS and ZDDOS. It is the same source file, an equate determines which variation you want to build. The wrapper mentioned above can be changed to pick either one. Basically, ZSDOS has more features. ZDDOS has less features, but inlcudes date stamping code. Refer to the zsdos.pdf file for more information. I have chosen to use ZSDOS to pick up the maximum number of features. DateStamping is still available, it just uses memory outside of the OS. + +The source also allows you to compile the OS code as either v1.1 or v1.2 via an equate. This can be controled by the wrapper just like the choice of ZSDOS/ZDDOS. Version 1.2 has only a couple of small changes versus v1.1 (apparently a minor bug fix). However, there are warnings in the source that compiling the DOS as v1.2 will make it incompatible with existing overlays and applications. I encountered this myself with the date stamping code -- won't work with v1.2 because it does a version check. For now, I have chosen to use v1.1 to maximize compatibility (seems to be what everyone is doing). Ultimately, I may go back and try to rebuild everything in the distribution to bring it all up to v1.2. That is for the future though. + +As I worked through the files in the distribution, it became clear that there were problems with the distribution. For example, the .CFG files for some apps (like FILEDATE) are not acceptable to ZCNFG. Additionally, the STAMPS.DAT file contains code that simply does not work. In all of these cases, I found updated or fixed versions of the files. However, the point is that I concluded I would need to go through the distribution file-by-file and validate everything, replacing anything that was not working as needed. See the notes below for what I did. + +Beyond the construction and integration of the actual DOS itself, the majority of the work has been to update the distribution files as needed to get them all functional. Then, as appropriate, I have added application files to the ROM Disk for the ZSystem builds. + +The remainder of this document details the changes I made as I went along. In all cases, my goal was to keep the result as close to the original distribution as possible. I started by copying all of the files from the distribution (contained in zsdos2.zip) into Support\ZSDOS. From there I tested, modified, updated, and customized as documented below. Finally, I cherry picked files that made sense to include on the ZSystem ROM disks. + +1. CLOCKS.DAT has been updated to include the N8VEM clock drivers, N8VEMCLK AND N8CLK. I have also added the SIMHCLOK clock driver. + +2. STAMPS.DAT has been replaced with an updated version. The update was called STAMPS11.DAT and was found on the Walnut Creek CP/M CDROM. The original version has a bug that prevents RSX (resident system extension) mode to fail to load properly. + +3. The original LDTIMD and LDTIMP were built against ZSDOS 1.0 and refused to load under ZSDOS 1.1. Used SETUPZST to recreate LDTIMD and LDTIMP for compatibility with ZSDOS 1.1. They were built exactly the same as previously: Relative Clock driver and RSX mode loading. + +4. Updated FILEDATE.COM and FILEDATE.CFG from original v1.7 to v2.1. The FILEDATE.CFG originally supplied was invalid. + +5. Updated COPY.CFG. The original one was invalid and appeared to be for a much oder version of COPY. + +6. Updated FILEATTR to v1.6A. Original FILEATTR.CFG was invalid. FILEATTR.CFG replaced with FA16.CFG. Added associated files FA16.DOC, FA16A.FOR, FA16CFG.TXT. + + +Usage Notes +----------- + +1. ZSDOS has a concept of fast relog of drives. This means that after a warm start, it avoids the overhead of relogging all the disk drives. There are times when this causes issues. After using tools like CLRDIR or MAP, you may need to run "RELOG" to get the drive properly recognized by ZSDOS. + +2. ZSVSTAMP expects to be running under the ZCPR 3.X command processor. By default, RomWBW uses ZCPR 1.0 (intentionally, to reduce space usage) and ZSVSTAMP will just abort in this case. It will work fine if you implement NZCOM. ZSVSTAMP is included solely to facilitate usage if/when you install NZCOM. + +3. FILEDATE only works with DateStamper style date stamping. If you run it on a drive that is not initialized for DateStamper, it will complain "FILEDATE, !!!TIME&.DAT missing". This is normal and just means that you have not initialized that drive for DateStamper (using PUTDS). + +4. ZXD will handle either DateStamper or P2DOS type date stamping. However, it MUST be configured appropriately. As distributed, it will look for P2DOS date stamps. Use ZCNFG to reconfigure it for P2DOS if that is what you are using. + +4. Many of the tools can be configured (using either ZCNFG or DSCONFIG). The configuration process modifies the actual application file itself. This will fail if you try to modify one that is on the ROM disk because it will not be able to update the image. + +5. DATSWEEP can be configured using DSCONFIG. However, DSCONFIG itself needs to be configured first for proper terminal emulation by using SETTERM. So, run SETTERM on DSCONFIG before using DSCONFIG to configure DATSWEEP! + +6. After using PUTDS to initialize a directory for ZDS date stamping, I am finding that it is necessary to run RELOG before the stamping routines will actually start working. + +7. Generic CP/M PIP and ZSDOS path searching do not mix well if you use PIP to copy to or from a directory in the ZSDOS search path. Best to use COPY from the ZSDOS distribution. \ No newline at end of file diff --git a/trunk/Doc/cpm22-m.pdf b/trunk/Doc/cpm22-m.pdf new file mode 100644 index 00000000..d030d4ac Binary files /dev/null and b/trunk/Doc/cpm22-m.pdf differ diff --git a/trunk/Doc/flash.man b/trunk/Doc/flash.man new file mode 100644 index 00000000..3b6a35df --- /dev/null +++ b/trunk/Doc/flash.man @@ -0,0 +1,42 @@ +NAME + flash - in-situ 29F040 flash ROM programmer for N8VEM, Zeta and N8 + computers. + +SYNOPSIS + flashz + flashn8 + +DESCRIPTION + The flashz and flashn8 erase and program the FLASH ROM chip from an + image file. flashz is used for the N8VEM Z80-SBC and Zeta computers. + flashn8 is used with the N8 home computer.

In most cases it is upward-compatible with the + original CP/M Version 2.2 CCP. + + ZCPR, however, provides many extensions to the CP/M CCP. + Included in these extensions are the following features: + + . The TYPE function can be made to page or not page its + output at the user's discretion + + . A LIST function is available which sends its output + to the CP/M LST: Device and does NOT page + + . The DIR command has been extended to allow the dis- + play of the system files or all files + + . The ERA command now prints out the names of the files + it is erasing + + . The current user number may be included as part of + the command prompt; if the user is under a number other than 0, + the prompt is of the form 'du>' (like 'A2>' or 'B10>'), and, if + the user is under 0, the prompt may be 'd>' or 'd0>' as per his + choice + + . The SUBMIT facility has been changed in two basic + ways: + - the prompt changes to 'du$' or 'd$' when the + SUBMIT command is printed + - the $$$.SUB is executed from drive A: (note that + the original SUBMIT problem now exists, but the new SUB.COM + facility corrects it); the CCP-GROUP definition of an Indirect + Command File now applies, and this definition is that any + sequence of commands which may be issued from the console is also + a valid sequence of commands for execution from an Indirect + Command File; hence, the sequence: + + DIR + B: + DIR + A: + + may be issued from either the console or an Indirect Command + File, and the results of the execution of this sequence are the + same. Basically, this says that Indirect Command Files are + upward-compatible to the console input (but not necessarily that + the contents of an Indirect Command File may be issued at the + console without modification). + + + Page 2 + + + + + + ZCPR - A Z80 Replacement for the CP/M CCP + + + + . A command-search hierarchy is now implemented which + is executed roughly as follows: + - the user's command is checked against the CPR- + resident commands and executed immediately if a match is found + - failing that, the current user number on the + current disk is scanned for the COM file; the COM file is loaded + and executed if found + - failing that, a default user number (initially 0 + but can be reset with the DFU CPR-resident command) on the cur- + rent disk is scanned for the COM file; the COM file is loaded and + executed if found + - finally, failing that, the default user number + on disk A: is scanned for the COM file; the COM file is loaded + and executed if found or an error message (COMMAND?, when COMMAND + was the user's command name) is printed + + . The numeric argument for the SAVE command can be + specified in hexadecimal so that the user may employ the values + presented by tools such as DDT exactly as they are given + + . A GET command which loads a file at a specified + memory address and a JUMP command which "calls" the subroutine at + a specified memory address have been added; a GO command which + "calls" the subroutine at 100H (subset of the JUMP capability) + has also been added + + + This document provides the user of ZCPR with the following + information: + + Part A: Installation Instructions + Part B: Usage Instructions and Explanation of Commands + Part C: ZCPR Command Levels and How to Use Them + + + + + + + + + + + + + + + + + + + + + + + + Page 3 + + + + + + ZCPR - A Z80 Replacement for the CP/M CCP + + + + Part A + Installation Instructions + + In order to install ZCPR on a target microcomputer (must be + currently running CP/M 2.2), the user must know two basic things: + + 1) Where his CCP is currently running in memory + 2) Where his CCP is located in the SYSGEN image, or, + for systems which don't support SYSGEN (such as P&T CP/M 2.2 for + the TRS-80 Model II), where his CCP is located on disk and how to + place the new ZCPR on top of it + + The first question is answered relatively easily. A pro- + gram, known as either BDOSLOC or BDLOC (for BDOS Locator), is + provided with ZCPR. You should assemble this program for your + particular computer (change the base ORG if you are running non- + ORG-0 CP/M) and execute it. Upon execution, it will provide you + with the base address of (1) the BDOS and (2) the CCP for your + particular system. BDOSLOC has worked correctly for all systems + tested so far, but there is always a chance that it may NOT work + for some non-tested system. For the time being, assume that it + works correctly and record the starting base page address of your + CCP. + + The second question is not answered nearly so easily. If + you have the ability to SYSGEN your system, it is much easier + (commonly) than if you do not. You must, after assembling the + ZCPR properly, integrate it into the sysgen (or disk) image of + CP/M. This can be done by obtaining a SYSGEN image of your + system, scanning it via a debugger such as DDT to find the offset + for the CCP, reading the new CPR in on top of the old one, and + finally running SYSGEN again to place the resultant system on + disk. If you DO NOT have SYSGEN capability, a Disk Utility + program is required to locate the CCP on disk and then write the + new ZCPR on top of the old one. The net result of this + integration is the placement of the new ZCPR onto disk in the + proper place so that it will be loaded with the rest of CP/M on + cold boot and executed properly. + To find the original CCP, you typically have to locate it by + its appearance. It is probably stored contiguously on disk, so, + once it is found, a sequential overwrite is all that is required. + Probability is extremely high that it is stored contiguously in + the SYSGEN image. The CCP starts with two (2) and ONLY TWO jump + instructions followed by a buffer area (possibly containing an + initial command and/or the Digital Research copyright notice). + The Digital Research manuals show the CCP to reside at address + 980H in the SYSGEN image, but this may vary with system. To + find this image, use DDT or some other such debugger, load the + SYSGEN image you can get via SYSGEN, and examine memory starting + at around 900H for the two (and ONLY two) jumps described above. + If you find an area with more than two jumps (a group of them), + you are probably looking at the BIOS and should go lower for the + CCP. The CCP will probably start on an even page or half-page + address (like 900H, 980H, 1100H, etc). + + + Page 4 + + + + + + ZCPR - A Z80 Replacement for the CP/M CCP + + + + Now that the location of the CCP has been found, record this + address for later. You are now ready for the integration of ZCPR + into your system. To do this, perform the following steps using + the information of the page address of the CCP (obtained from + BDOSLOC and called CPRLOC within ZCPR) and the SYSGEN image + address of the CCP (called IMAGE for reference in this document). + + 1. Edit ZCPR and set the CPRLOC equate to the value + obtained from above. Also set any flags and values as you desire + (see the section on ZCPR Customization below). When satisfied, + end the edit session. + + 2. Assemble ZCPR with MAC (or equivalent). This + assembler is required because of the MACROs used. Only the + resultant HEX file is required. + + 3. Assuming that you can use SYSGEN, obtain a SYSGEN + image of your current CP/M system and save it on disk. + + 4. Load the SYSGEN image into memory with DDT (or + equivalent). Once loaded, verify that the original CCP is at the + IMAGE address found above and compute the integration offset + using the DDT H command: + H, + The second number displayed gives you the OFFSET value required + for step 5. + + 5. Integrate ZCPR into your SYSGEN image via DDT's I + and ROFFSET commands. Use IZCPR.HEX (or the name of your version + of ZCPR) to load the FCB and ROFFSET (where OFFSET was computed + in step 4) to load the ZCPR.HEX file into memory at the proper + location. Check to see that ZCPR is indeed properly loaded by + examining the SYSGEN IMAGE area. + + 6. Place the new system on disk by running SYSGEN and + NOT loading the system from disk (use the memory image). + + For further clarification of the above process, the + following is a sample terminal session which outlines the steps + taken. + + ZCPR Integration Example + + + B>; Sample terminal session for integrating ZCPR + B>sysgen + SYSGEN VER 2.2 + SOURCE DRIVE NAME (OR RETURN TO SKIP)b + SOURCE ON B, THEN TYPE RETURN <-- I hit the RETURN key here + FUNCTION COMPLETE / + DESTINATION DRIVE NAME (OR RETURN TO REBOOT) <-- and here + B>save 44 cpm56.com <-- We now have a SYSGEN image of CP/M + to work with + + + + Page 5 + + + + + + ZCPR - A Z80 Replacement for the CP/M CCP + + + B>xdir + XDIR Version 2.6 User Number: 0, Double Density + File Attributes: Non-System + + Filename.Typ Size K Filename.Typ Size K Filename.Typ Size K + -------- --- ------ -------- --- ------ -------- --- ------ + !TEXTWRK.-12 0 CPR .DOC 8 EE687 .TXT 4 + CPR .AQM 34 TFS .HLP 6 EE687PRE.TXT 4 + CPR .ASM 50 CONTENTS.T01 6 SW1 .TXT 10 + CPR .BAK 4 CONTENTS.T02 4 SW2 .TXT 2 + CPM56 .COM 12 CONTENTS.T03 4 + B: 30 Entries & 22 Files -- 338K Bytes Remaining + File Data: 14 Files -- 154K Bytes Displayed + B>bdosloc <-- Now to locate the CCP's address + The Base Page Address of this system's BDOS is C5 + The Base Page Address of this system's CCP is BD <-- This is it + B>ddt cpm56.com <-- Now to find the CCP in the SYSGEN image + DDT VERS 2.0 + NEXT PC + 2D00 0100 + -d900,90f <-- Start looking around here + 0900 31 80 E7 3E 06 3C 3C FE 1B CA 00 C2 DA 11 E7 D6 1..>.<<......... + -da00,a0f + 0A00 31 00 01 01 01 0C C5 CD 0F E4 21 00 BE 11 00 04 1.........!..... + -db00,b0f + 0B00 31 00 01 01 01 11 C5 CD 0F E4 21 00 C0 11 00 02 1.........!..... + -db80,b8f + 0B80 31 00 01 01 09 01 CD A8 00 21 00 D2 11 00 C2 0E 1........!...... + -- Detail Left Out -- + -d1100 <-- I found it at 1100H; note the 2 JMP's + 1100 C3 FF BD C3 FB BD 50 10 20 20 20 20 20 20 20 20 ......P. + 1110 20 20 20 20 20 20 20 20 00 00 00 00 00 00 00 00 ........ + 1120 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ + -- Detail Left Out -- + -^C <-- Return to CP/M; I know that CPRLOC will be + BD00H and the IMAGE offset is 1100H + + B>ed cpr.asm {edit ZCPR here and place CPRLOC=BD00H}# + -- Detail Left Out -- + + B>mac cpr $pz sz <-- Now to assemble the CPR + CP/M MACRO ASSEM 2.0 + C4F0 <-- Note that CPR MUST end before BDOS + begins! + 014H USE FACTOR + END OF ASSEMBLY + + + + + + + + + + + + Page 6 + + + + + + ZCPR - A Z80 Replacement for the CP/M CCP + + + + + B>ddt cpm56.com <-- Now to integrate! + DDT VERS 2.0 + NEXT PC + 2D00 0100 + -h1100,bd00 <-- Compute offset for new CPR + CE00 5400 <-- Offset is 5400H + -icpr.hex <-- Init FCB + -r5400 <-- Read in new CPR with offset + NEXT PC + 2D00 0000 + -^C <-- Done! + B>sysgen <-- Now to SYSGEN onto disk + SYSGEN VER 2.2 + SOURCE DRIVE NAME (OR RETURN TO SKIP) <-- Use memory image + DESTINATION DRIVE NAME (OR RETURN TO REBOOT)b <-- onto B: + DESTINATION ON B, THEN TYPE RETURN + FUNCTION COMPLETE + DESTINATION DRIVE NAME (OR RETURN TO REBOOT) <-- Done for now + + B> + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Page 7 + + + + + + ZCPR - A Z80 Replacement for the CP/M CCP + + + + Setting the ZCPR Inline Options + + The following are the four basic options available to the + user under ZCPR for customization of his package. + + Option Name Function + + REL Configures CPRLOC (CPRLOC equ 0) for integration + via MOVCPM rather than the DDT/SYSGEN technique + outlined above; set to TRUE for MOVCPM integra- + tion or FALSE for DDT/SYSGEN integration + + BASE Base address of your CP/M system; standard CP/M + has a base of 0, but some CP/M systems (such as + for the TRS-80 Model I and Heath/Zenith H89/Z89) + start physical RAM memory at a higher address; + equate BASE to the starting RAM memory address of + your system + + CPRLOC This is the starting address of ZCPR; set the + second CPRLOC equate to the address you obtain + from BDOSLOC + + RAS This is an equate which masks out selected ZCPR + command functions for security purposes on + Remote Access Systems such as Bulletin Boards; + the masked out functions currently include + SAVE, ERA, REN, JUMP, GO, and GET; set RAS to TRUE + to mask these out or FALSE to leave them in + + SUBA This is an equate which determines the drive + onto which ZCPR will look for an executing + Indirect Command File.

ZCPR is written as a logical extension of the CP/M 2.2 + CCP philosophy and should be addressed as such. + + + + The ZCPR Command Hierarchy Search + + The first, and most basic thing, to learn about ZCPR is the + order in which is searches for a COM file for execution or a file + specified by the GET command. Under the CP/M 2.2 CCP, if the + specified COM file command was not found on the current drive in + the current user area, the CCP aborted with an error message. + ZCPR, however, continues searching from this point a maximum of + two more levels. This command hierarchy search was outlined + above and is described here in further detail. + + 1. If the command is of the form 'COMMAND' and NOT + 'd:COMMAND', the CPR-resident command list is searched for a + match. If the match is found, the CPR-resident command is + immediately processed. If the match is not found or the command + is of the form 'd:COMMAND', the next step is taken. Note that + the 'd:COMMAND' form is good for executing a command COM file + which has the same name as a CPR-resident command (such as SAVE + or DIR). + + 2. If the command is of the form 'd:COMMAND', disk + drive 'd:' is temporarily logged in for the purpose of the + command search. Otherwise, the currently logged-in drive is + used. + + 3. Now the file named COMMAND.COM is searched for. If + found, it is loaded into memory starting at 100H and executed. + If not, proceed to step 4. + + 4. Now that the first search for COMMAND.COM has + failed, the CPR checks to see if the user is under the current + Default User Number. The Default User Number may be that set by + the DEFUSR equate in the CPR or that set by the user via the DFU + command. DEFUSR is in effect if DFU has not been issued since + the last Warm or Cold Boot, and DFU is in effect if it was issued + since the last Warm or Cold Boot. If the user is NOT under the + current Default User Number, ZCPR temporarily logs him into it + and searches the directory. If COMMAND.COM is found, it is + loaded as described above and executed. If not, ZCPR proceeds to + the next step. + + + + + + Page 11 + + + + + + ZCPR - A Z80 Replacement for the CP/M CCP + + + + 5. The user is now in the Default User Number, and at + this point, ZCPR checks to see if the user is on disk drive A:. + If not, it temporarily logs into A: and searches the default user + number of A: for COMMAND.COM. If found, it is loaded as + described above and executed. If not, ZCPR prints the command + name as an error message and returns to command input mode, + aborting the SUBMIT file if COMMAND came from it. + + In all cases of the search above, if COMMAND.COM is found, + after it is loaded into memory, ZCPR resets the user to his + original disk drive and user number. Hence, the files referenced + by the user by default are obtained from this environment. + + To illustrate this command hierarchy search, consider the + following examples: + + Example 1: DEFUSR equ 0 {default user number is 0} + + B10> <-- User is on Drive B:, User Number 10 + B10>ASM TEST.BBZ <-- User wishes to assemble TEST.ASM in + Drive B:, User 10 + <-- At this point, ZCPR looks on B:/10 for ASM.COM, fails, + looks on B:/0, fails, and finally looks on A:/0; it + finds ASM.COM here and goes back to B:/10 for the file + + + Example 2: DEFUSR equ 0 and DFU issued + + B10> <-- User is on Drive B:, User Number 10 + B10>DFU 5 <-- User Selects User 5 as default + B10>ASM TEST.BBZ <-- As above + <-- At this point, ZCPR looks on B:/10 for ASM.COM, fails, + look on B:/5, fails, and finally looks on A:/5; it + fails here also and prints ASM? as an error message + + Example 3: DEFUSR equ 0 + + B> <-- User is on Drive B:, User Number 0 + B>ASM TEST.BBZ <-- As above + <-- At this point, ZCPR looks on B:/0 for ASM.COM, fails, + looks on A:/0, fails, and prints error message + + Example 4: DEFUSR equ 0 + + A10> <-- User is on Drive A:, User Number 10 + A10>ASM TEST.AAZ <-- As above, but file on A: + <-- At this point, ZCPR looks on A:/10 for ASM.COM, fails, + looks on A:/0, fails, and prints error message + + + + + + + + + Page 12 + + + + + + ZCPR - A Z80 Replacement for the CP/M CCP + + + + Another Example: + + For example, if the user is logged into Drive B: in + User Area 10, the Default User Number is 0, and the following COM + files are present as indicated -- + + WM.COM on Drive A: in User 0 + MBASIC.COM on Drive A: in User 0 and on + Drive B: in User 0 + TEST.COM on Drive B: in User 10 and Drive B: + in User 0 + + then the following happens when the following commands are + issued from the console (or Indirect Command File): + + B10>WM TEST2.TXT + \ \ \__ File to be edited + \ \__ Invoke the WM.COM file (Word Master editor) + \__ User is on Drive B: in User Area 10 + + Results: + ZCPR searches B: User 10, B: User 0, and A: User 0 for + WM.COM; it finds WM.COM in A: User 0, loads it, logs the user + back into B: User 10, and executes it. + + B10>MBASIC + \ \__ Invoke the MBASIC.COM file (MBASIC Interpreter) + \__ User is on Drive B: in User Area 10 + + Results: + ZCPR searches B: User 10 and B: User 0 for MBASIC.COM; + it finds MBASIC.COM in B: User 0, so it doesn't bother to look on + A: User 0.

Each level constitutes a different + way to issue a command for ZCPR to process. + + Command Levels 1 and 2 are common to all implementations of + CP/M and CP/ZM from CP/M Version 1.4. Command Level 1 is that + command level in which the command is issued by the user from his + console terminal. The prompt 'd>' or 'du>' appears on the + terminal, and the user is allowed to enter the command with + editing from the terminal. Command Level 2 is that command level + in which the command is entered from an executing $$$.SUB file. + + In both cases, the command is stored in the internal ZCPR + buffer called CIBUFF (Command Input BUFFer). Under both Command + Levels 1 and 2, the command is placed into this buffer, the + characters of the command line are capitalized, a character count + which indicates the number of characters in the command line is + stored in CBUFF (the byte before CIBUFF), an ending binary 0 is + placed after the last character in the command line, and the + internal pointer CIBPTR (Command Input Buffer PoinTeR) is set to + point to CIBUFF (the first character of the command line). + + Command Level 3 is an extended concept to Command Levels 1 + and 2 which is specifically supported by ZCPR Version 1.0 and + beyond. This command level allows a transient program to place a + command line into CIBUFF and the character count into CBUFF and + have this command line executed by ZCPR. Once control is trans- + ferred to ZCPR to execute the command line, the transient program + which placed the command line loses control and the command is + executed exactly as though it had been typed by the user at his + console terminal. + + In order for a transient program to utilize the Command + Level 3 facility, this program MUST do the following: + + 1. Locate the ZCPR. Since the ZCPR is ALWAYS 2K bytes + in size and located directly under the BDOS, the transient can + locate the ZCPR by examining the BDOS entry page address at + location 7 and subtracting 8 from this number (8 pages = 2K + bytes). The resulting number is the base page address of ZCPR. + + 2. Store the command line in CIBUFF and the character + count in CBUFF. Knowing the base page address of ZCPR, the + following information is useful in doing this: + + + + + + + + Page 19 + + + + + + ZCPR - A Z80 Replacement for the CP/M CCP + + + + + ORG CPRLOC ;Base Address of ZCPR + JMP CPR ;Enter ZCPR and Execute Default Cmd + JMP CPR1 ;Enter ZCPR and Don't Execute + MBUFF: DB BUFLEN ;Size of CIBUFF in bytes + CBUFF: DS 1 ;Number of Bytes in Command Line + CIBUFF: DS BUFLEN ;Buffer for Command Line + DS 1 ;Buffer for Ending 0 (set by ZCPR) + CIBPTR: DS 2 ;Address of CIBUFF (set by ZCPR) + + + 3. Obtain the User/Disk Flag. Location 4 contains + this number, but the user may select a flag of his choice. This + flag is one byte long, and the high-order nybble (4 bits) + contains the user number and the low-order nybble contains the + disk number to process the command from. The User/Disk Flag is + to be passed to ZCPR in the C Register. + + 4. When ready, transfer control to ZCPR to process the + command by JMPing to the base address of ZCPR. The first JMP in + the JMP Table given above is at this address. At this time, ZCPR + will log in the user and disk in the User/Disk Flag and process + the Command Level 3 Command Line. + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + Page 20 + +

*** +*** *** +*** System Software for N8VEM Z80 Projects *** +************************************************************ + +Builders: Wayne Warthen (wwarthen@gmail.com) + Douglas Goodall (douglas_goodall@mac.com) + David Giles (vk5dg@internode.on.net) + +Updated: 2012-08-28 +Version: 2.1.1 + +This is an adaptation of CP/M-80 2.2 and ZSDOS/ZCPR +targeting ROMs for all N8VEM Z80 hardware variations +including SBC, Zeta, and N8. + +NOTE: This is very much a work-in-progress. It is +severely lacking appropriate documentation. I am +happy to answer questions and provide support though. + +Acknowledgements +---------------- + +While I have heavily modified much of the code, I want +to acknowledge that much of this is derived or +copied from the work of others in the N8VEM +project including Andrew Lynch, Dan Werner, Max Scane, +David Giles, John Coffman, and probably many others +I am not clearly aware of. + +I especially want to credit Douglas Goodall for +contributing code, time, testing, and advice. +He has created an entire suite of application +programs that substantially enhance this ROM. Everything +in the Apps folder of the distribution came directly +from Douglas and the list includes cpmname, writesys, +assign, slices, termtype, drives, and others. + +David Giles has contributed support for building the +ROM under Linux and the CSIO support in the SD Card driver. + +Usage Instructions +------------------ + +The distribution includes many pre-built ROM +images in the Output directory. The simplest way of +using this ROM is to simply pick the pre-built ROM +that most closely matches your preferences, burn it, +and use it. + +Refer to the file called RomList.txt for a complete +list of the ROMs that are included and the required +hardware configuration that they support. + +CPU Speed & Baud Rate +--------------------- + +The startup serial port baud rate in all pre-built +RomWBW variants is 38.4Kbps. While this speed is +nice in that it provides great display and file +transfer performance, it does push the limits of +slower hardware. Specifically, XModem v12.5 (the +default XM.COM) on the distribution is unable to +service the serial port fast enough if the CPU is +running at 4MHz. Your options are to 1) use the +old version of XModem (XM5.COM), put a faster CPU +oscillator in your system (6MHz or above), or +3) decrease the baud rate by building a custom +ROM. + +CP/M vs. ZSystem +---------------- + +There are two OS variants included in this distribution +and you may choose which one you prefer to use. + +The traditional Digital Research (DRI) CP/M code is the first +choice. The ROM images that DO NOT end in "_z" are built +with the traditional CP/M components from DRI. The Doc +directory contains a manual for CP/M usage (cpm22-m.pdf). +If you are new to the N8VEM systems, I would currently +recommend using the CP/M ROMs to start with simply +because they have gone through more testing and you +are less likely to encounter problems. + +The other choice is to use the most popular non-DRI +CP/M "clone" which is generally referred to as +ZSystem. The ROM images with a "_z" suffix are built +using the ZSystem components (specifically ZSDOS 1.2 +and ZCPR 1.0). These are intended to be +functionally equivalent to CP/M and should run all +CP/M 2.2 code. They are optimized for the Z80 CPU +(as opposed to 8080 for CP/M) and have some potentially +useful improvements. Please refer to the Doc directory +and look at the files for zsdos and zcpr (zsdos.pdf & +zcpr.doc as well as ZSystem.txt). + +ZSystem builds contain ZSDOS specific files in the +ROM Disk. + +Building a Custom ROM +--------------------- + +I strongly suggest you start with burning one of the +pre-built ROMs and making sure that works first. Once +you have gotten past that hurdle, you should consider +building a custom ROM. It is very easy and the +distribution comes with everything that is needed to +run a build on a Windows 32 bit or 64 bit system -- +basically Windows XP or above. There is also a +Linux build now available. + +Creating a custom ROM allows you to customize a lot +of useful stuff like adding support for a DSKY if +you have one. + +Please refer to the Build.txt file in the Doc directory +for detailed instructions for building a custom ROM. If +you are using Linux, also read the LinuxBuild.txt file. + +Notes +----- + +I realize these instructions are very minimal. I am happy to answer +questions. You will find the Google Group 'N8VEM' to be a great +source of information as well. \ No newline at end of file diff --git a/trunk/RomDsk/CPM_1024KB/ASM.COM b/trunk/RomDsk/CPM_1024KB/ASM.COM new file mode 100644 index 00000000..a63e5aec Binary files /dev/null and b/trunk/RomDsk/CPM_1024KB/ASM.COM differ diff --git a/trunk/RomDsk/CPM_1024KB/CLRDIR.COM b/trunk/RomDsk/CPM_1024KB/CLRDIR.COM new file mode 100644 index 00000000..d1f2a7d6 Binary files /dev/null and b/trunk/RomDsk/CPM_1024KB/CLRDIR.COM differ diff --git a/trunk/RomDsk/CPM_1024KB/CR.COM b/trunk/RomDsk/CPM_1024KB/CR.COM new file mode 100644 index 00000000..8a824bcc Binary files /dev/null and b/trunk/RomDsk/CPM_1024KB/CR.COM differ diff --git a/trunk/RomDsk/CPM_1024KB/DDT.COM b/trunk/RomDsk/CPM_1024KB/DDT.COM new file mode 100644 index 00000000..83f8603f Binary files /dev/null and b/trunk/RomDsk/CPM_1024KB/DDT.COM differ diff --git a/trunk/RomDsk/CPM_1024KB/DDTZ.COM b/trunk/RomDsk/CPM_1024KB/DDTZ.COM new file mode 100644 index 00000000..e30a34c0 Binary files /dev/null and b/trunk/RomDsk/CPM_1024KB/DDTZ.COM differ diff --git a/trunk/RomDsk/CPM_1024KB/DDTZ.DOC b/trunk/RomDsk/CPM_1024KB/DDTZ.DOC new file mode 100644 index 00000000..e4470528 --- /dev/null +++ b/trunk/RomDsk/CPM_1024KB/DDTZ.DOC @@ -0,0 +1,564 @@ + + DDTZ v2.7 + by C.B. Falconer + edited by George A. Havach + +Introduction: +============ +DDTZ v2.7 is a complete replacement for DDT, Digital Research's +famous Dynamic Debugging Tool, with improved functionality, bug +extermination, and full Z80 support. In general, DDTZ is fully +compatible with the original utility, but it has extra and +extended commands and many fewer quirks. All Z80-specific +instructions can be (dis)assembled, though in Intel rather then +Zilog format. Furthermore, DDTZ will correctly trace ('T' and 'U' +commands) both 8080 and Z80 instructions, depending on which CPU +is operating. On startup, the program announces which CPU it is +running on. + +DDTZ v2.7 now handles the 64180 added opcodes. It does NOT test +for a 64180 CPU, since this cannot be done without executing +illegal Z80 instructions, which in turn will crash some +simulators. However v2.7 does not execute any 64180 instructions +internally, only in the subject program. + +This issue supplies the "M" version assembled, to avoid errors +when switching between MSDOS and CPM systems. The command table +is updated accordingly. Most CPM users are also MSDOS users, but +not vice-versa. + +The program is invoked by typing + + ddtz +or + ddtz [d:]filespec + +In the second form, DDTZ will load the specified file into +memory starting at 0100H, unless it's a .HEX file that sets its +own load address. Besides reporting the NEXT free address and +the PC (program counter) after a successful load, DDTZ also shows +the number of memory pages needed for a SAVE. Instead of having +to write all this down, just use the 'X' command at any time to +redisplay these three values for the current application. + +NOTE: loading more code above the NEXT pointer revises these + values. + +As in DDT, when a program is loaded above the area holding the +'A' and 'U' (and now 'W') command code, these commands are +disabled, and the extra memory is released to the user. Thus, +DDTZ can occupy as little as 3K total memory space. Unlike DDT, +however, DDTZ will not overwrite itself or the system on program +loads (except .HEX files). + +At initialization, the stack pointer (SP) points to a return to +DDTZ, just like for the CCP. Thus, programs that normally return +to the CCP will be returned to DDTZ. The 'B' command +reinitializes this condition. + + +The intercept vector copies the BDOS version number, etc., so +an object program does not know that DDTZ is running (except +for BIOS-BDOS vector size). Thus, programs that check the version +number should execute correctly under DDTZ. + +All input parameters can now be entered in any of three formats: + + (1) hexadecimal (as in DDT), + (2) decimal, by adding a leading '#' character, + (3) ASCII, by enclosing between either single or double + quotes; either one or two characters are allowed. + +Leading blanks in command lines and parameters are absorbed. +Either a comma or a (single) space is a valid delimiter. +Either uppercase or lowercase input is accepted. + +The default command (for anything not otherwise recognizable) +is 'H'. This allows convenient calculation, along with the other +features described below. So, to convert a number, just enter +it! + +As in DDT, the prompt character is '-', and the only error +message is the query ('?'), which generally kicks you back to +command mode. + +New Commands (Over DDT): +======================= + +NOTE: letters in parenthesis, e.g. "(U)", show the equivalent + command for DDTZM version (compatible with MSDOS debug). + + @ Sets or shows (with no parameter) the internally stored + "base" value. Also used with the 'S' and 'D' commands as + an optional parameter (though without the '@') to display + memory from an arbitrary base marker (offset). When set to + zero (the default), it does not affect any screen displays. + + B B)egin: resets the USER stack pointer to its initial value, + such that any program that exits by an RET will return to + DDTZ. DDTZ provides a default stack space of + approximately 24 bytes for user programs. + + C C)ompare first_address,last_address,against_address: shows + all the byte differences between two memory areas, in the + format + + XXXX aa YYYY bb + + where XXXX and YYYY are the comparative memory addresses, + and aa and bb are the corresponding byte values. Can be + used to verify the identity of two files by first + loading them into different memory areas with the 'R' + command (see below). + + + W Write: stores the modified memory area to disk under the + (K) filename specified by the 'I' command, overwriting the + original file from which it was loaded (the user is queried + before doing so). By default, the image of memory from + 0100H through the "NEXT" value -1 is saved. "K first_addr, + last_address" overrides this and allows writing ANY memory + area to a file. Almost a necessity for CPM 3.0 (no SAVE!). + K)eep on DDTZ + + X eXamine: redisplays the "NEXT PC SAVE" report at any time. + (Q) Q)uery size on DDTZ. + + S S)earch first_address, last_addr, value: searches the + (W) specified memory area for the value (a 16-bit word, not a + byte) and shows the locations of all such. Very useful for + finding CALL's or JMP's to a particular address, etc. + W)here on DDTZ + + Y Y)our_option parm1,parm2,address: executes an arbitrary + routine at the specified address, with the BC and DE + registers set to parm1 and parm2, respectively. + + Z Displays (but does not alter) the Z80's alternate register + set, including the index registers (disabled if running on + an 8080). On Z80's, automatically included as the last + part of the display by the 'X' command. + + +Based (Offset) Displays: +======================= + +The 'D' and 'E' commands can use a stored base value (offset), +as set by the '@' command. The current @ value may be +overridden for a single execution of these commands by adding the +base as an extra parameter in the command line. The effect is +to add this value to the first/last address and display +accordingly. The address listing on the left becomes XXXX:YYYY, +where XXXX is the offset address and YYYY is the actual memory +address being displayed. For example, if you have a data area +located at 42B7H and wish to preserve easy access, just enter +"@42b7". Now, "d0,3f" will dump memory starting at 4237H. + + +Further Changes from DDT: +======================== + + A A)ssemble now accepts the full Z80 as well as 8080 + instruction set, although it expects them in Intel rather + than Zilog format (see notes below under the 'L' + command). When in doubt, see the mnemnonic list below. + + D D)isplay or D)ump will accept an optional third parameter + to set the base value for a single execution only. Format + has been cleaned up. + + H H)ex_arithmetic on two values also shows their + difference in decimal. With only one value, converts to + hexadecimal, decimal, and ASCII (low-order byte only). + + + N N)ame now allows drive specification (d:...) and sets up + (I) the complete command line, including both FCB's (at + addresses 005CH and 006CH). The tail (stored at 0081H up) + is NOT upshifted. + I)nput on DDTZ + + U U)nassemble now displays the raw hexcode, especially handy + (L) when examining non-code areas. Intel (8080 style) mnemonics + are used, so some disassembled instructions may look + strange. E.g., the Z80's 'IN B,(C)' and 'OUT (C),B' become + 'INP B' and 'OUTP B', respectively; 'LD (nnnn),BC' becomes + 'SBCD nnnn', 'ADD IX, BC' becomes 'DADX B', and 'JP (IX)' + becomes 'PCIX'. + L)ist on DDTZ + + L L)oad now permits loading a file into memory with an + (R) offset, which is added to the default load address of + 0100H. When reading in a .HEX file with a preset bias, + the 'R' command will not transfer control to an invalid + execution point. Another execution of the 'R' command will + reread the input file, e.g.: + + n blah + l + ...modify the code and generally mess about... + l + + The original file is reloaded, and the modifications are + removed. + R)ead on DDTZ + + E E)nter, like D)isplay, now accepts an optional second + (S) parameter to set the base value for a single execution + only. + S)ubstitute or S)et on DDTZ + + T T)rap/trace on termination now shows the complete CPU + state. Traps and traces no longer lock up when a user RST + 7 instruction is executed. Tracing of BDOS/BIOS calls is + heavily trun cated, avoiding clutter and preventing system + crashes. + +NOTE: Most of the UNDOCUMENTED Z80 op-codes are handled. Others + can crash the system. + + R R)egisters also shows what two-byte values the HL and SP + (X) registers are actually pointing to. On Z80's, displays the + alternate register set. + eX)amine on DDTZ + +NOTE: Any use of the 'W' or 'L' command resets the system DMA + transfer address to the standard default value of 0080H. + + +;

The TPA is the amount of memory + available in your computer for use by programs that have a + file type of COM. To see how big the TPA is in your computer, + press the question mark key (?) at the Opening Menu. + + The amount of memory required by WordStar can be reduced by + approximately 3 kbytes if necessary. Use the WSCHANGE program + to select the minimum memory configuration option. The menu + will show you what capabilities are being reduced. + + WordStar uses a general-purpose buffer for a variety of + tasks. WordStar allocates memory to this buffer for editing, + for merge printing, and at the Opening Menu (see BFSIZE in + PATCH.LST). The buffer used for editing is usually the most + sensitive to a reduced TPA size. (You may be able to use the + Opening Menu and print, but there may be insufficient memory + for editing.) + + The merge print buffer is used only to hold merge print + variable names and data. Increase it if you run out of memory + while merge printing. + + The Opening Menu buffer is used primarily to hold the file + directory, and for miscellaneous tasks. + + +LOW-MEMORY INDICATOR IN STATUS LINE +----------------------------------- + + If the Low-Memory indicator appears in the status line, it + means that WordStar was unable to complete some function. + The most common symptoms are: the line number in the + status line is wrong, or a paragraph alignment could not be + completed. You may correct the line counter by saving your + file, exiting WordStar, and re-loading your file. To correct + the paragraph alignment, move your cursor to the point where + paragraph alignment stopped, and then press ^B again. + + The reason this comes up is that WordStar was not able to fit + a big enough chunk of text into memory at one time. + + When you first begin editing, WordStar uses the value from + EDSIZE in the user area to determine the minimum amount + of memory required for a page of text. The default + is set for approximately a 55 line by 66 column page. If + your page size is routinely larger than this, you may want + to increase EDSIZE. Multiply the number of lines by the + number of columns, and divide by 128. + + If the Low-Memory indicator comes on while printing, it is due + to either the same reasons as for editing, or there is + insufficient memory to print the text proportionally spaced. + The amount of memory required depends on which printer + driver you are using. If you aren't using the .PS ON dot + command to turn proportional spacing on in your document, + low memory won't be a problem. Also, WordStar uses more + memory for merge printing than it does for regular printing + (around 2.5 kbytes more). + + The Low-Memory indicator will also appear when a full disk error + is encountered during editing. Treat the disk-full error as you + would normally. + + +RAM-RESIDENT PROGRAMS +--------------------- + + RAM-resident programs, such as SmartKey, reduce the amount of + working memory (TPA) that WordStar can use. The new features in + WordStar, such as shorthand, may reduce the need for these + RAM-resident programs, thus freeing memory for WordStar. + + +ZCPR3 SUPPORT +------------- + + In order to enable the ZCPR facilities within WordStar, the user + must use the Z3INS utility provided with ZCPR to install the + address of the ZCPR "environment" into WordStar. The environment + contains information that WordStar uses to support ZCPR-specific + functions. + + Generally, the user should log onto the drive containing the file + WS.COM, and issue the command: + + Z3INS SYS.ENV WS.COM + + The user should also run either WINSTALL or WSCHANGE to further + install WordStar for ZCPR. However, this is not mandatory because + the only thing that happens is that the WordStar sign-on says + "ZCPR3," and the LGLUSR location in the user area is changed for a + maximum user number of 31. (The normal default for LGLUSR is 15.) + + Once the user has installed WordStar for use with ZCPR, the user + will be able to use the following ZCPR features: + + - A named directory may be used when logging onto a new drive/user. + + - A named directory may be used instead of a drive/user as part + of any file name. + + - The drive/user always appears above file directories. (For CP/M + only the drive letter is shown if the user number is zero.) + + - The directory name also appears above the directory if one has + been defined for the currently logged drive/user. + + - If WordStar does not find its OVR files on the current drive and + user, it will search the drives and user numbers in the ZCPR + search path rather than using its standard search pattern. + + - WordStar installs itself as a ZCPR "shell" process which lets the + user enter any legal ZCPR command when running a program. (CP/M + can only run programs that are COM files.) + + +OSBORNE USERS +------------- + + The command to change a hard carriage return to a soft carriage + return (document mode) or to turn Auto-indent ON (nondocument + mode) does not function on the Osborne because of a limitation + in its BIOS. The following patch can be applied to change the + command from ^^ to ^- (Ctrl-Hyphen): + + Using DDT or SID in the file WSMSGS.OVR: + + At 02DA replace 1E with a 1D + At 02EF replace 1E with a 1D + At 0359 replace 1E with a 1D + At 06B2 replace 1E with a 1D + At 06C9 replace 1E with a 1D + + At the system prompt type SAVE 53 WSMSGS.OVR + + For more information on how to use SID or DDT, see your CP/M + reference guide. As always, be sure and apply the patch to a + COPY of the file. + + +INSTRUCTIONS FOR TWO FLOPPY DISK COMPUTERS +------------------------------------------ + + Do not remove the Program disk while you are using WordStar. + + The Printer Driver Library file (WSPRINT.OVR) on the WordStar + program disk is much smaller than the Printer Driver Library + file contained on the disk labeled PRINTER. Be sure to read the + section in "Starting" that discusses the printer library file. + + +RUN A PROGRAM +------------- + + Once you press R you can type the drive and user number for the + program you want to run. You may run only .COM files. CCP commands, + such as DIR cannot be used. + + +INDEXING +-------- + +Using StarIndex + + StarIndex 1.01 works with files created with this release of + WordStar. + +"Can't Use That Printer" Message + + When WordStar creates an index or table of contents, it uses + the printer drivers $INDEX and $TOC. If you created a smaller + WSPRINT.OVR file, you may have left these drivers out. To + return them to the file, copy the original WSPRINT.OVR file + onto your disk. When you create a smaller file again, be sure + to save these drivers. See Appendix C in the WordStar manual + for a list of other drivers to save. + + +SPELL CHECKING +-------------- + + Dual floppy disk users: + + Unless you have sufficient room on your working WordStar program + disk for the files TW.COM, SPELL.COM, MARKFIX.COM, REVIEW.COM and + MAINDICT.CMP you will not be able to run a spell check from the + Opening Menu. You will need to exit WordStar and replace the + working WordStar program disk with the dictionary disk you created + during installation. This disk should contain the files listed + above. Make sure the disk in drive B has the file you want to + spell-check. + + Follow the directions for running a spell check in The WORD Plus + manual. + + +UPGRADING FROM A PREVIOUS RELEASE +--------------------------------- + + This release of WordStar contains many new features and commands. + See the "What's New" booklet for a complete list. The following + changes came in too late to be included in the documentation. + +Printer Patches + + Previous versions of WordStar treat most dot matrix printers + and other non-daisy wheel printers as a DRAFT printer with a + few patchable items. Because of this, many users have used + these patches to be able to use certain features of their + printers. Sometimes the patches have been quite extensive, and + some users have many files that count on them. + + The printer drivers of WordStar Release 4, on the other hand, + are very powerful. Almost every driver recognizes all the print + controls and all the dot commands. In fact, if a document is + written to be printed on one kind of printer, it is likely that + it will also print fine on some other printer. + + However, if you want to use your existing files with WordStar + 4, and those files rely on the user area being patched in a + special way, you can probably do so by moving the patches into + WordStar 4, and using the CUSTOM or SIMPLE printer driver. + + On the INSTALL disk is a program called MOVEPRN.COM that + copies the printer driver portion of the previous release's + user area into files that can be installed into Release 4 with + the "auto patcher" feature. + + Copy the program MOVEPRN.COM onto the disk containing the + WS.COM file for the previous version. Type + + MOVEPRN WS.COM FILE1.PAT FILE2.PAT + + MOVEPRN extracts the proper portions of the user area and + writes them into two files that may then be used with the "auto + patcher" feature of WSCHANGE. + + FILE1.PAT is to be used with the general patching menu + (Choose E "Patching" on the WSCHANGE Main Menu, then A "Auto + Patcher"). FILE2.PAT should be used to install strings first + into the SIMPLE driver, and then into the CUSTOM driver (choose + B "Printer" on the WSCHANGE Main Menu, then B "Printer driver + library", D "Change printer driver data" and D "Driver auto + patcher"). + + Test print your document first with the SIMPLE driver, and then + with the CUSTOM driver to see which one produces the most + satisfactory results. + + Also read Appendix C for more information on using the Auto + Patcher. + + +Hanging Indents + + For WordStar Professional Release 4, MailMerge reformats indented + text created with ^OG to the current margins. If you want the text + to remain indented, use embedded ruler lines or the .RM, .LM, + and .PM commands. See the "Reference Guide" for more information. + + Pressing ^OG to wrap back to the first tab on the ruler line after + having reached the last tab works the same way it did in previous + versions of WordStar, contrary to what is stated in the manual. + + +TERMINALS +--------- + + WordStar comes installed for an "idealized" special terminal. + WINSTALL and WSCHANGE allow you to install many terminals by + name, thus allowing WordStar to take advantage of the special + features that the terminal might support, such as underlining + or the function keys. + + Use either WINSTALL or WSCHANGE to pick your specific terminal + or computer screen from the Monitor menu. If your terminal + isn't on the menu, it probably emulates one of those that is + there. Look in your terminal documentation to find out. + + After you install WordStar for the proper terminal, run + WordStar and open the file PRINT.TST to see which attributes + (such as bold and underline) work on your screen. + WordStar will highlight the following in some way... + + Bold (^PB) + Underline (^PS) + Strike-out (^PX) + Subscript (^PV) + Superscript (^PT) + Doublestrike (^PD) + Italics (^PY) + Blocks (^KB, ^KK) + Error messages + + Most of the time, normal text will be shown in dim intensity, + and highlighted text will be shown in bright intensity. You + may have to use a brightness and/or contrast knob to adjust + your screen the first time you use WordStar this way. + + If your dim intensity is too dim to see well, and you can't + adjust it, you can change the BRITE flag to ON using WSCHANGE. + This will invert bright and dim in your text, so that regular + text is displayed bright, and highlighted text will be + displayed as dim. However, text in the menus is not affected. + + +DISPLAY PROBLEMS WITH TERMINALS +------------------------------- + + Once you have installed WordStar for the proper terminal, you + may still experience display problems. + + If text from the previous screen remains after WordStar + displays a new screenful of text, the most likely cause is + cursor wrap. Basically, WordStar must know what happens to the + cursor when a character is displayed at the rightmost position + of the screen. It can either remain at the right edge, or it + can wrap to the beginning of the next line. The WRAP flag in + WordStar must be set either on or off to correspond to the + way the terminal works. (It is generally set for the + terminal's factory default, but the default can usually be + changed using the terminal's setup mode.) + + Another possible cause for display problems is your terminal's + incomplete emulation of some other terminal. The most + common differences are... + + Line insert (LININS), line delete (LINDEL), + Erase to end of screen (ERAEOS), + Erase to end of line (ERAEOL), + And, erase screen (ERASCR). + + Look in the manual for your terminal and use WSCHANGE to see + if the control sequences match. + + +PRINTERS +-------- + +WHAT'S IN THIS SECTION + + This section contains the following information: + + Choosing a Printer + Setting Up Your Printer + Printer Drivers + Proportional Printing + Laser Printers + Information on Specific Printers + +CHOOSING A PRINTER + + WordStar is ready to work with over 100 printers. The printer you + choose during installation becomes your default printer. However, + when you print a document, you can choose any other printer. To + choose a default printer, follow these steps: + + 1. Look at the Printer Information brochure that came in your + package. The first chart shows the printers listed on the + Printer Selection Menus. If your printer is on the menu, + simply choose it during installation. + + 2. If your printer isn't listed on the menu, it may work like a + printer that is. Refer to the second chart in the Printer + Information brochure for a list of printers that work like + printers on the menu. When WordStar asks you to choose a + printer, choose the printer that works like yours. + + 3. If neither chart lists your printer, choose Typewriter Printer + (if your printer can backspace) or Draft Printer (if it can't). + These choices may not take advantage of all your printer's + features, but they will work with almost any printer. + + Note: If you choose Draft or Typewriter, you can modify custom + print controls and printer initialization. + + If you want to make more modifications to take advantage of your + printer's feature, choose the Custom or Simple drivers, then use + the WS Printer Patches section of WSCHANGE to tell WordStar the + codes for your printer. Refer to your printer manual for these + codes. Some printers work better with the Custom driver and some + with the Simple driver. Try using both and see which works better + with your printer. See the "Reference Guide" for more information. + +SETTING UP YOUR PRINTER + +Choosing a Printer Port + + Each printer is connected to a printer port at the back of + the computer. WordStar looks for printers on the LST: port. + If your printer is connected to a different port, use + WSCHANGE to tell WordStar the correct port. + +Testing Your Printer Connection + + At the operating system prompt, type "PIP LST:=READ.ME." This + file should be printed by your printer. If it is not, your printer + may be connected to a different port. See your computer reference + manual, and the section on the STAT command in your CP/M + reference manual for more information. + + +PRINTER DRIVERS + + The WSPRINT.OVR file on the Printers disk contains a printer + driver for each printer on the Printer Selection Menu. The printer + driver for a printer contains all the codes WordStar needs to work + with that printer. + + Each printer driver has a short name. If you choose a printer when + you print a document, you see the names of the printer drivers, not + the names of the printers. + +PROPORTIONAL PRINTING + + WordStar supports proportional printing on a number of printers. + To turn on proportional printing, either install WordStar to + default to proportional printing, or place a ".PS on" command + in your document. At print time, WordStar selects the + appropriate proportional font based on the character width + (.CW) currently in effect. + + The specific printer descriptions later in this section show + recommended character widths for proportional typefaces. + These widths are for a normal mix of upper- and lowercase + letters. If you have many words or phrases all in uppercase + or if you want your text less densely printed, choose a larger + character width. + + While WordStar mostly sets character widths based on the + proportional-width table in the driver, on the more advanced + daisy wheel printers, WordStar uses the printer's proportional- + spacing mode. WordStar determines how much white space is needed + to right-justify the line based on its own proportional width + tables. If the table values don't match the wheel installed, + WordStar won't be able to justify the line correctly. + + WordStar sends standard ASCII characters; if a proportional wheel + uses a different spoke mapping, set up the printer to handle this. + +LASER PRINTERS + + WordStar supports laser printer features such as font changes + and proportional spacing. + + WordStar supports several laser printers: the Canon LPB-8 A1 & A2; + the Hewlett-Packard LaserJet, LaserJet+, and LaserJet 500+; + and the Ricoh LP4080. Refer to the "Specific Printer + Information" section of this file for information on these + printers. General notes about using laser printers are given below. + +Paper Size and Margins + + Laser printers come with preset page margins. You need to + compensate for these margins by changing page length in your + WordStar documents. The chart below shows the recommended + settings for 8 1/2 X 11 inch paper for both portrait and landscape + orientations. These settings allow 55 lines of text for portrait + orientation and 40 lines of text for landscape orientation (at 6 + lines per inch). They also allow for a footer of up to 3 lines + and a one-line header. If you use multiple-line headers, adjust + the top margin accordingly. + + Dot Default Portrait Landscape + Setting Command Value Orientation Orientation + ------- ------- ------- ----------- ----------- + page length .PL 66 62 47 + top margin .MT 3 2 2 + bottom margin .MB 8 5 5 + header margin .HM 2 1 1 + footer margin .FM 2 2 2 + + If the laser printer is your primary printer, you can use WSCHANGE + to make these settings the defaults. + + Because laser printers leave small margins at the left and right + sides of the page, you may want to use a smaller page offset + setting (the default is .PO 8). + +Form Feeds + + When you print with a laser printer, answer Y for yes to the "Use + form feeds (Y/N)?" prompt at print time. (The default is NO.) If + the laser printer is your primary printer, you can use WSCHANGE to + change the default to yes. + +WordStar Commands for Font Selection + + The WordStar dot commands and print control commands listed below + determine the fonts used for printing a document. + + .PR .PR OR=L selects landscape orientation; .PR OR=P (or just + .PR OR) selects portrait orientation (the default). If + either of these commands appears after the first printing + line on a page, the orientation will not change until the + following page. + + .PS .PS ON selects proportionally spaced characters; .PS OFF + (the default) selects fixed-spaced characters. + + .CW The character-width setting (.CW followed by the width in + 120ths of an inch) determines the character pitch and font + selected for fixed-width printing. For proportional fonts, it + determines the point size and proportional-width table + selected. + + .LQ .LQ ON selects near letter quality print (if supported by + your printer). LQ OFF selects draft quality print. Default + is ON. + + ^PY The italic print control toggles between normal and italic + characters when the appropriate italic font is available. + + ^PB The boldface print control toggles between normal and bold + characters when the appropriate bold font is available. + + ^PD The double strike print control used with the laser printers + toggles overprinting with a horizontal offset of 1/120" + between the two character images. This allows a bold effect + where no bold font is available. + + ^PA ^PA turns alternate pitch on. Use .CW to assign different + character widths to normal pitch (see ^PN below) and alternate + pitch so that each pitch accesses a different font. You can + then change fonts by switching between the two pitches. This + is the only way to use two fonts on the same line. + (See "Character width" and "Pitch" in the "Reference Guide.") + + ^PN ^PN turns normal pitch on. You can use it with ^PA as + described above. + + ^P@ When working with columns, if you use alternate and normal + pitch for two fonts, or if you use proportional spacing, you + may need to use ^P@ to make sure the columns line up. + Remember that the column position set with ^P@ is determined + by the normal pitch character width. (See "Columns" and + "Proportional spacing" in the "Reference Guide." + +INFORMATION ON SPECIFIC PRINTERS + + This section describes the capabilities of each printer listed on + the Printer Selection Menu. The printers are listed in alphabetical + order (except for the generic printers such as "Draft," + "Typewriter," "Custom," "Simple," and the various print-to-disk + options, which are listed first). + + There is a chart for each printer explaining how features work and + listing any special notes about the printer.

Falconer + edited by George A. Havach + +Introduction: +============ +DDTZ v2.7 is a complete replacement for DDT, Digital Research's +famous Dynamic Debugging Tool, with improved functionality, bug +extermination, and full Z80 support. In general, DDTZ is fully +compatible with the original utility, but it has extra and +extended commands and many fewer quirks. All Z80-specific +instructions can be (dis)assembled, though in Intel rather then +Zilog format. Furthermore, DDTZ will correctly trace ('T' and 'U' +commands) both 8080 and Z80 instructions, depending on which CPU +is operating. On startup, the program announces which CPU it is +running on. + +DDTZ v2.7 now handles the 64180 added opcodes. It does NOT test +for a 64180 CPU, since this cannot be done without executing +illegal Z80 instructions, which in turn will crash some +simulators. However v2.7 does not execute any 64180 instructions +internally, only in the subject program. + +This issue supplies the "M" version assembled, to avoid errors +when switching between MSDOS and CPM systems. The command table +is updated accordingly. Most CPM users are also MSDOS users, but +not vice-versa. + +The program is invoked by typing + + ddtz +or + ddtz [d:]filespec + +In the second form, DDTZ will load the specified file into +memory starting at 0100H, unless it's a .HEX file that sets its +own load address. Besides reporting the NEXT free address and +the PC (program counter) after a successful load, DDTZ also shows +the number of memory pages needed for a SAVE. Instead of having +to write all this down, just use the 'X' command at any time to +redisplay these three values for the current application. + +NOTE: loading more code above the NEXT pointer revises these + values. + +As in DDT, when a program is loaded above the area holding the +'A' and 'U' (and now 'W') command code, these commands are +disabled, and the extra memory is released to the user. Thus, +DDTZ can occupy as little as 3K total memory space. Unlike DDT, +however, DDTZ will not overwrite itself or the system on program +loads (except .HEX files). + +At initialization, the stack pointer (SP) points to a return to +DDTZ, just like for the CCP. Thus, programs that normally return +to the CCP will be returned to DDTZ. The 'B' command +reinitializes this condition. + + +The intercept vector copies the BDOS version number, etc., so +an object program does not know that DDTZ is running (except +for BIOS-BDOS vector size). Thus, programs that check the version +number should execute correctly under DDTZ. + +All input parameters can now be entered in any of three formats: + + (1) hexadecimal (as in DDT), + (2) decimal, by adding a leading '#' character, + (3) ASCII, by enclosing between either single or double + quotes; either one or two characters are allowed. + +Leading blanks in command lines and parameters are absorbed. +Either a comma or a (single) space is a valid delimiter. +Either uppercase or lowercase input is accepted. + +The default command (for anything not otherwise recognizable) +is 'H'. This allows convenient calculation, along with the other +features described below. So, to convert a number, just enter +it! + +As in DDT, the prompt character is '-', and the only error +message is the query ('?'), which generally kicks you back to +command mode. + +New Commands (Over DDT): +======================= + +NOTE: letters in parenthesis, e.g. "(U)", show the equivalent + command for DDTZM version (compatible with MSDOS debug). + + @ Sets or shows (with no parameter) the internally stored + "base" value. Also used with the 'S' and 'D' commands as + an optional parameter (though without the '@') to display + memory from an arbitrary base marker (offset). When set to + zero (the default), it does not affect any screen displays. + + B B)egin: resets the USER stack pointer to its initial value, + such that any program that exits by an RET will return to + DDTZ. DDTZ provides a default stack space of + approximately 24 bytes for user programs. + + C C)ompare first_address,last_address,against_address: shows + all the byte differences between two memory areas, in the + format + + XXXX aa YYYY bb + + where XXXX and YYYY are the comparative memory addresses, + and aa and bb are the corresponding byte values. Can be + used to verify the identity of two files by first + loading them into different memory areas with the 'R' + command (see below). + + + W Write: stores the modified memory area to disk under the + (K) filename specified by the 'I' command, overwriting the + original file from which it was loaded (the user is queried + before doing so). By default, the image of memory from + 0100H through the "NEXT" value -1 is saved. "K first_addr, + last_address" overrides this and allows writing ANY memory + area to a file. Almost a necessity for CPM 3.0 (no SAVE!). + K)eep on DDTZ + + X eXamine: redisplays the "NEXT PC SAVE" report at any time. + (Q) Q)uery size on DDTZ. + + S S)earch first_address, last_addr, value: searches the + (W) specified memory area for the value (a 16-bit word, not a + byte) and shows the locations of all such. Very useful for + finding CALL's or JMP's to a particular address, etc. + W)here on DDTZ + + Y Y)our_option parm1,parm2,address: executes an arbitrary + routine at the specified address, with the BC and DE + registers set to parm1 and parm2, respectively. + + Z Displays (but does not alter) the Z80's alternate register + set, including the index registers (disabled if running on + an 8080). On Z80's, automatically included as the last + part of the display by the 'X' command. + + +Based (Offset) Displays: +======================= + +The 'D' and 'E' commands can use a stored base value (offset), +as set by the '@' command. The current @ value may be +overridden for a single execution of these commands by adding the +base as an extra parameter in the command line. The effect is +to add this value to the first/last address and display +accordingly. The address listing on the left becomes XXXX:YYYY, +where XXXX is the offset address and YYYY is the actual memory +address being displayed. For example, if you have a data area +located at 42B7H and wish to preserve easy access, just enter +"@42b7". Now, "d0,3f" will dump memory starting at 4237H. + + +Further Changes from DDT: +======================== + + A A)ssemble now accepts the full Z80 as well as 8080 + instruction set, although it expects them in Intel rather + than Zilog format (see notes below under the 'L' + command). When in doubt, see the mnemnonic list below. + + D D)isplay or D)ump will accept an optional third parameter + to set the base value for a single execution only. Format + has been cleaned up. + + H H)ex_arithmetic on two values also shows their + difference in decimal. With only one value, converts to + hexadecimal, decimal, and ASCII (low-order byte only). + + + N N)ame now allows drive specification (d:...) and sets up + (I) the complete command line, including both FCB's (at + addresses 005CH and 006CH). The tail (stored at 0081H up) + is NOT upshifted. + I)nput on DDTZ + + U U)nassemble now displays the raw hexcode, especially handy + (L) when examining non-code areas. Intel (8080 style) mnemonics + are used, so some disassembled instructions may look + strange. E.g., the Z80's 'IN B,(C)' and 'OUT (C),B' become + 'INP B' and 'OUTP B', respectively; 'LD (nnnn),BC' becomes + 'SBCD nnnn', 'ADD IX, BC' becomes 'DADX B', and 'JP (IX)' + becomes 'PCIX'. + L)ist on DDTZ + + L L)oad now permits loading a file into memory with an + (R) offset, which is added to the default load address of + 0100H. When reading in a .HEX file with a preset bias, + the 'R' command will not transfer control to an invalid + execution point. Another execution of the 'R' command will + reread the input file, e.g.: + + n blah + l + ...modify the code and generally mess about... + l + + The original file is reloaded, and the modifications are + removed. + R)ead on DDTZ + + E E)nter, like D)isplay, now accepts an optional second + (S) parameter to set the base value for a single execution + only. + S)ubstitute or S)et on DDTZ + + T T)rap/trace on termination now shows the complete CPU + state. Traps and traces no longer lock up when a user RST + 7 instruction is executed. Tracing of BDOS/BIOS calls is + heavily trun cated, avoiding clutter and preventing system + crashes. + +NOTE: Most of the UNDOCUMENTED Z80 op-codes are handled. Others + can crash the system. + + R R)egisters also shows what two-byte values the HL and SP + (X) registers are actually pointing to. On Z80's, displays the + alternate register set. + eX)amine on DDTZ + +NOTE: Any use of the 'W' or 'L' command resets the system DMA + transfer address to the standard default value of 0080H. + + +;

Several additional features are available under ZCPR3, +including error flag setting, error handler invocation, an +enhanced display, and better error detection. + +FA will not run under CP/M 3.0 or Z3PLUS. + +USAGE: + + FILEATTR {dir:}{afn} {{/}options} + +If a DIR or DU specification is not given, the current directory +is assumed (under vanilla CP/M only the drive is significant). +If no ambiguous or unambiguous filename is given, all files +("*.*") are matched. + +If no attribute options are given, FILEATTR merely displays the +current state of each file's attributes. Files are displayed in +the order that they appear in the directory. + +Once operation begins, FA cannot be aborted by the user. If a ^C +is entered at the keyboard, all screen output stops, but file +attribute operations continue to completion. If that was not the +case, attributes might be set on some entries for a file and not +on others. Nevertheless, suppressing screen output speeds things +up a bit. + +OPTIONS: A leading slash is required unless the option list is +the second parameter on the command line. Options may be +separated by spaces, commas, or nothing at all. + +ATTRIBUTE OPTIONS: These options set (turn on) corresponding +attributes on files matching the file specification. Attributes +not specified by an attribute option remain unchanged. + +If the option is preceded by a minus ("-") or by an "N", the +corresponding attribute is reset (turned off). + + 1 F1. This is a user attribute which has no predefined + meaning. + + P Public (f2). Under ZSDOS, when this attribute is set, + a file is available from any user area of the disk on + which it resides. A file cannot be made public if + another file with the same name exists in any other + user area on that drive. In that case FA will issue an + error message and leave the attribute off. + + D Inhibit access datestamp (f3). Under ZSDOS, when this + attribute is set, the file's access datestamp will not + be updated, which may speed file access slightly. If + the attribute is turned off, normal access datestamping + resumes. + + 4 F4. This is a user attribute which has no predefined + meaning. + + W Wheel protect (f8). Under ZSDOS, when this attribute + is set, the file becomes read-only when the wheel byte + is off and cannot be erased. If the wheel byte is on, + the file can be erased normally. + + R Read only (t1). When this attribute is set, the file + cannot be erased or modified by most programs. + + S System (t2). When this attribute is set, the file + becomes a "hidden" file that will not be found by most + directory programs or by most well-behaved utilities + that accept ambiguous filenames. (FA must find system + files, of course.) + + A Archive (t3). When this attribute is set, it signals + some archival programs that the file has not been + modified since it was last backed up. If a file is + modified, ZSDOS and ZRDOS turn this attribute off. + CP/M does not fully support this attribute, however. + +OTHER OPTIONS: These options affect only the screen display. + + Q Quiet mode. Console output is suppressed unless there + is an error. All other operations are performed + normally. + + X Screen paging off. With this option, screen paging is + turned off. The screen can still be paused by pressing + any key except ^C. + +ERRORS: Under ZCPR3, errors will cause FA to set the program +error flag and to invoke the error handler. The error flag will +be set to the following values: + 2 invalid directory specification + 4 miscellaneous (conflicting file, no files on disk) + 10 no matching files found (no error handler) + 18 Disk read-only + 19 Invalid option + +For error code 10 (no matching files found), the error flag is +set, but the error handler is not called. + +In addition, under ZCPR 3.3 and above, an invalid directory +specification will abort FA to the error handler, but no message +is printed. + +The following error messages may be seen: + +Conflicting entry, can't set public attribute + If there are files with the same name in other user areas of + the disk, the public attribute cannot be set. + +No files on disk + The disk directory is empty. + +Bad Option: /o + The command line option shown is unknown to FILEATTR. + +Drive R/O + The drive is set to read-only by the operating system and + attributes cannot be changed. + +CP/M version 2.x required + FILEATTR will not run on this system. + +BIOS write error near directory sector n + An error occurred at or near the given directory sector, + which is expressed as a decimal offset from the beginning of + the directory. + +BIOS set track detected - FA aborting + A background program is attempting to modify the current + track setting. The background program must be removeed + before running FA again. + +Not Wheel + Under ZCPR3 the wheel byte must be set before FILEATTR can + be run. + +CONFIGURATION: While no installation is necessary, all options +can be set as defaults, if you prefer, using ZCNFG. The +configuration options are fully explained on the ZCNFG help +screens. + +It is best not to change the name of the configuration file. Its +special name assures that ZCNFG will always find the correct CFG +file, even if the name of FA has been changed or if more than one +version of FA is online. + +HISTORY: + +Version 1.6 -- April 14, 1991 -- Gene Pizzetta + Now displays target DU and directory name in summary. Fixed + bug that caused "GO" to be displayed as program name, if it + was re-invoked with the GO command. + +Version 1.5 -- March 27, 1991 -- Gene Pizzetta + Now calls CP/M version checking routine (it was there, but + it wasn't called). Changed error codes: 10, no matching + files found. "No files on disk" error now gets + miscellaneous error code (4). Error 10 does not invoke + error handler. Not released. + +Version 1.4 -- March 20, 1991 -- Gene Pizzetta, Howard Goldstein + Code to check module data byte (S2) was replaced by Howard + Goldstein's elegant solution which uses a "true" extent + number: ((data_mod * 32) + extent). Entering a ^C no + longer really aborts FILEATTR; instead FA immediately prints + "Wait..." on the screen, turns off paging, turns on quiet + mode, sets the results flag, and finishes what it was doing. + All this is to prevent unexpected results when only some of + a file's directory entries are changed. All errors + including a conflicting file found during a PUBLIC request, + now set the program error flag and invoke the error handler + so an active SUBMIT or ZEX script can be aborted. The error + flag will have the following values: 2, invalid directory; + 10, no files on disk; 18, disk is read-only; 19, invalid + option; 4, all other errors. If no matching files are + found, the program error flag will be set to FFh, but the + error handler will not be invoked. A few other code changes + were made, including a check for CP/M-Plus, under which + FILEATTR will not work. Not released. + +Version 1.3 -- February 22, 1991 -- Gene Pizzetta + Corrected bug that caused faulty operation on large files: + The module data byte (S2) byte was not being checked, so + such files appeared 2 or more times in the directory display + and the public routine was often not finding conflicting + files. Added configuration byte and command line option (X) + for screen paging (paging is suppressed in quiet mode). + Made quiet mode responsive to ZCPR quiet flag and changed Q + command line option to toggle. Usage screen reflects + current effect of X and Q toggles. Attribute configuration + area changed to be compatible with ZCNFG TOGL3 routine. + Actions of D and ND options reversed so they work the same + as the others. Added configuration byte for printing + summary line even in quiet mode, as suggested by Howard + Goldstein. Removed blank lines from screen display, + allowing three more filenames to be shown. Removed tabs + from usage screen so PRINT and PSTR are not needed. + Eliminated leading zero from user number display. Now + prints "file" instead of "files" in summary when only 1 + matching file is found. Ditto for attribute(s) altered. + +Version 1.2 -- November 30, 1988 -- Carson Wilson + Fixed bug of no program name display when FILEATTR's name + was 8 characters long. + +Version 1.1 -- October 30, 1988 -- Carson Wilson + Now wildcards the command forms "FA d: /options" and "FA d: + options." + +Version 1.0 -- September 26, 1988 -- Carson Wilson + If a filespec is given, no leading slash is required before + the options. Link with version 4 libraries. Removed /X + option--ZSDOS 10T always closes the first extent when a file + is written to. Changed summary to read "files matched". + +Version 0.9 -- July 7, 1988 -- Carson Wilson + Increased length of search FCB (AMBFIL) by one byte. Set up + AMBFIL as '?' + 35 binary 0's. ZRDOS and CP/M zero the + drive byte (FCB+0) during search next calls, so reinitialize + it to '?' before rescanning the directory. PROGID now + prints stored name on GO/JUMP. + +Version 0.8 -- June 26, 1988 -- Carson Wilson + Use SYSLIB PRINT for help display. VPRINT does not expand + tabs. Now traps disk track changes at the BIOS level. + Allows '-' as well as 'N' for "negate option." Auto- + wildcards FCB1 for attribute set as well as display. + +Version 0.7 -- May 24, 1988 -- Carson Wilson + Cosmetic changes to help, display. Made public routines + faster by 1/2 directory scan average. Consolidated file + attribute setting/resetting routines for efficiency and + clarity. + +Version 0.6 -- May 14, 1988 -- Carson Wilson + Changed "Publ" to "Publc" and "Priv" to "Privt". Added Q + and X options, made options installable. Added test for bad + ZCPR directory & chain to error handler. + +Version 0.5 -- May 4, 1988 -- Carson Wilson + Fixed bug at CHKRO inherited from MAKE.ASM.

Help now fully "smart" under ZCPR. + Reworked VID3.Z80 and VID4.Z80 from VLIB11 and moved them + into FA.Z80 (see end of file).

INTRODUCTION + + ZSVSTAMP is a utility program that saves the create +date/time stamp of a given file in memory. At a later time, +ZSVSTAMP can restore the create stamp to a file. This can be +useful when modifying a file with an editor that actually creates +a new copy of the file rather than modifying it in place. +ZSVSTAMP allows the original creation date of the document to be +retained. + + In order to support all types of date stamping under ZSDOS, +ZSVSTAMP uses the get/set stamp functions of ZSDOS (or ZDDOS) and +thus may only be run under these operating systems. It also +requires ZCPR3 with multiple command line, external FCB and +message buffer. If an attempt is made to run ZSVSTAMP on a +system that does not meet these requirements, the program will +abort with an error message. + + + +2.0 OPERATION + + ZSVSTAMP has two modes of operation -- Manual and Automatic. + + + +2.1 Automatic Mode + + This mode is the most commonly used. It is extremely well +suited for use in alias scripts and can make the whole process of +saving and restoring date stamps virtually transparent to the +user. The syntax is: + + ZSVSTAMP approg [ufn] + +where "approg" is the program, such as an editor, that you wish +to run and "ufn" is an unambiguous file name to be modified by +"approg." When a command of this type is given, ZSVSTAMP saves +"ufn"'s creation date in protected memory. It then causes +"approg" to be run, and when "approg" finishes, ZSVSTAMP is +automatically run again to restore the original create stamp to +"ufn." If "ufn" does not exist, or if the disk does not support +date stamping, ZSVSTAMP displays a warning message and +immediately passes control to "approg" without attempting to save +a stamp. In this situation, ZSVSTAMP is not rerun when "approg" +completes execution. + + Some editors allow a syntax such as + + EDIT oldfile newfile + +When ZSVSTAMP is invoked with more than one parameter following +the application name, no stamps are saved or restored. This +feature can be disabled if desired, (see the section on +customization). + + + +2.2 Manual Mode + + Manual mode can be used to save or restore a file's create +stamp. The syntax is: + + ZSVSTAMP ufn /G or /S + +to Get or Save a file's create stamp, or: + + ZSVSTAMP ufn /P or /R + +to Put or Restore a saved stamp back onto a file. + + + +3.0 CUSTOMIZING ZSVSTAMP + +There are five configuration flags located near the beginning of +the program. Each flag is preceeded by an ASCII string to help +identify its function. These flags may be patched to customize +ZSVSTAMP as desired. + + The first four flags determine whether or not various +warning messages can be displayed when ZSVSTAMP is being run in +Automatic Mode. Setting a flag to 0 disables its associated +message; any other value enables the message. The flags are +labeled "NOSTMP," "NOFILE," "READERR," and "UPDTERR," and they +affect the "Disk has no time/date stamps," "File not found," +"Can't read time/date stamp," and "Can't update time/date stamp" +messages respectively. The program is distributed with all four +messages enabled. Please note that these flags have no effect in +Manual Mode where error messages are always enabled. + + The fifth and final configuration flag is labeled +"REPLALWS." It determines what ZSVSTAMP will do when more than +one parameter follows the application name in an Automatic Mode +command. If the byte following the "REPLALWS" label equals 0, +ZSVSTAMP checks to see if there is more than one parameter +following the application program name. If there is, ZSVSTAMP +simply exits to the application without saving or updating any +stamps. (This is the default setting in the distributed +version.) If the "REPLALWS" flag is non-zero, no such check is +made. + + + +4.0 CONTACTING THE AUTHOR + + Howard Goldstein may be contacted at: + + Newton Centre Z-Node, (Z-Node 3): 617/965-7259 + + Ladera Z-Node, (Z-Node 2): 213/670-9465 + + Home phone, (voice): 203/787-1918 + \ No newline at end of file diff --git a/trunk/RomDsk/ZSYS_1024KB/ZXD.CFG b/trunk/RomDsk/ZSYS_1024KB/ZXD.CFG new file mode 100644 index 00000000..f202ae59 Binary files /dev/null and b/trunk/RomDsk/ZSYS_1024KB/ZXD.CFG differ diff --git a/trunk/RomDsk/ZSYS_1024KB/ZXD.COM b/trunk/RomDsk/ZSYS_1024KB/ZXD.COM new file mode 100644 index 00000000..20395673 Binary files /dev/null and b/trunk/RomDsk/ZSYS_1024KB/ZXD.COM differ diff --git a/trunk/RomDsk/ZSYS_512KB/CLRDIR.COM b/trunk/RomDsk/ZSYS_512KB/CLRDIR.COM new file mode 100644 index 00000000..d1f2a7d6 Binary files /dev/null and b/trunk/RomDsk/ZSYS_512KB/CLRDIR.COM differ diff --git a/trunk/RomDsk/ZSYS_512KB/COPY.CFG b/trunk/RomDsk/ZSYS_512KB/COPY.CFG new file mode 100644 index 00000000..3d5310ac Binary files /dev/null and b/trunk/RomDsk/ZSYS_512KB/COPY.CFG differ diff --git a/trunk/RomDsk/ZSYS_512KB/COPY.COM b/trunk/RomDsk/ZSYS_512KB/COPY.COM new file mode 100644 index 00000000..87c0c2fb Binary files /dev/null and b/trunk/RomDsk/ZSYS_512KB/COPY.COM differ diff --git a/trunk/RomDsk/ZSYS_512KB/DDT.COM b/trunk/RomDsk/ZSYS_512KB/DDT.COM new file mode 100644 index 00000000..83f8603f Binary files /dev/null and b/trunk/RomDsk/ZSYS_512KB/DDT.COM differ diff --git a/trunk/RomDsk/ZSYS_512KB/DIF.COM b/trunk/RomDsk/ZSYS_512KB/DIF.COM new file mode 100644 index 00000000..87b89d75 Binary files /dev/null and b/trunk/RomDsk/ZSYS_512KB/DIF.COM differ diff --git a/trunk/RomDsk/ZSYS_512KB/DSCONFIG.COM b/trunk/RomDsk/ZSYS_512KB/DSCONFIG.COM new file mode 100644 index 00000000..b77dd008 Binary files /dev/null and b/trunk/RomDsk/ZSYS_512KB/DSCONFIG.COM differ diff --git a/trunk/RomDsk/ZSYS_512KB/DUMP.COM b/trunk/RomDsk/ZSYS_512KB/DUMP.COM new file mode 100644 index 00000000..03a77c3c Binary files /dev/null and b/trunk/RomDsk/ZSYS_512KB/DUMP.COM differ diff --git a/trunk/RomDsk/ZSYS_512KB/ED.COM b/trunk/RomDsk/ZSYS_512KB/ED.COM new file mode 100644 index 00000000..a0f0f541 Binary files /dev/null and b/trunk/RomDsk/ZSYS_512KB/ED.COM differ diff --git a/trunk/RomDsk/ZSYS_512KB/FA16.CFG b/trunk/RomDsk/ZSYS_512KB/FA16.CFG new file mode 100644 index 00000000..b7974d36 Binary files /dev/null and b/trunk/RomDsk/ZSYS_512KB/FA16.CFG differ diff --git a/trunk/RomDsk/ZSYS_512KB/FILEATTR.COM b/trunk/RomDsk/ZSYS_512KB/FILEATTR.COM new file mode 100644 index 00000000..4527d090 Binary files /dev/null and b/trunk/RomDsk/ZSYS_512KB/FILEATTR.COM differ diff --git a/trunk/RomDsk/ZSYS_512KB/FILEDATE.CFG b/trunk/RomDsk/ZSYS_512KB/FILEDATE.CFG new file mode 100644 index 00000000..da1ca45f Binary files /dev/null and b/trunk/RomDsk/ZSYS_512KB/FILEDATE.CFG differ diff --git a/trunk/RomDsk/ZSYS_512KB/FILEDATE.COM b/trunk/RomDsk/ZSYS_512KB/FILEDATE.COM new file mode 100644 index 00000000..11b83616 Binary files /dev/null and b/trunk/RomDsk/ZSYS_512KB/FILEDATE.COM differ diff --git a/trunk/RomDsk/ZSYS_512KB/FLASH.MAN b/trunk/RomDsk/ZSYS_512KB/FLASH.MAN new file mode 100644 index 00000000..e57de5c2 --- /dev/null +++ b/trunk/RomDsk/ZSYS_512KB/FLASH.MAN @@ -0,0 +1,35 @@ +NAME + flash - in-situ 29F040 flash ROM programmer for N8VEM, Zeta and N8 computers +SYNOPSIS + flashz + flashn8 +DESCRIPTION + The flashz and flashn8 erase and program the FLASH ROM chip from an + image file. flashz is used for the N8VEM Z80-SBC and Zeta computers. + flashn8 is used with the N8 home computer.

BIOSEX is zero if your BIOS is normal size, +; and can be negative if your BIOS is in PROM or in +; non-contiguous memory. +; +; RAS - Remote-Access System; setting this equate to TRUE disables +; certain CPR commands that are considered harmful in a Remote- +; Access environment; use under Remote-Access Systems (RBBS) for +; security purposes +; +REL EQU FALSE ;SET TO TRUE FOR MOVCPM INTEGRATION +; +BASE EQU 0 ;BASE OF CP/M SYSTEM (SET FOR STANDARD CP/M) +; + IF REL +CPRLOC EQU 0 ;MOVCPM IMAGE + ELSE +; +; If REL is FALSE, the value of CPRLOC may be set in one +; of two ways. The first way is to set MSIZE and BIOSEX +; as described above using the following three lines: +; +;MSIZE EQU 56 ;SIZE OF MEM IN K-BYTES +;BIOSEX EQU 0 ;EXTRA # K-BYTES IN BIOS +;CPRLOC EQU 3400H+(MSIZE-20-BIOSEX)*1024 ;CPR ORIGIN +; +; The second way is to obtain the origin of your current +; CPR using BDSLOC or its equivalent, then merely set CPRLOC +; to that value as as in the following line: +; +CPRLOC EQU 0D000H ;FILL IN WITH BDOSLOC SUPPLIED VALUE +; +; Note that you should only use one method or the other. +; Do NOT define CPRLOC twice! +; +; The following gives the required offset to load the CPR into the +; CP/M SYSGEN Image through DDT (the Roffset command); Note that this +; value conforms with the standard value presented in the CP/M reference +; manuals, but it may not necessarily conform with the location of the +; CPR in YOUR CP/M system; several systems (Morrow Designs, P&T, Heath +; Org-0 to name a few) have the CPR located at a non-standard address in +; the SYSGEN Image +; +;CPRR EQU 0980H-CPRLOC ;DDT LOAD OFFSET +CPRR EQU 1100H-CPRLOC ;DDT LOAD OFFSET FOR MORROW DESIGNS + ENDIF +; +RAS EQU FALSE ;SET TO TRUE IF CPR IS FOR A REMOTE-ACCESS SYSTEM +; +; The following is presented as an option, but is not generally user-customiz- +; able. A basic design choice had to be made in the design of ZCPR concerning +; the execution of SUBMIT files. The original CCP had a problem in this sense +; in that it ALWAYS looked for the SUBMIT file from drive A: and the SUBMIT +; program itself (SUBMIT.COM) would place the $$$.SUB file on the currently +; logged-in drive, so when the user was logged into B: and he issued a SUBMIT +; command, the $$$.SUB was placed on B: and did not execute because the CCP +; looked for it on A: and never found it. +; After much debate it was decided to have ZCPR perform the same type of +; function as CCP (look for the $$$.SUB file on A:), but the problem with +; SUBMIT.COM still exists. Hence, RGF designed SuperSUB and RLC took his +; SuperSUB and designed SUB from it; both programs are set up to allow the +; selection at assembly time of creating the $$$.SUB on the logged-in drive +; or on drive A:. +; A final definition of the Indirect Command File ($$$.SUB or SUBMIT +; File) is presented as follows: +; "An Indirect Command File is one which contains +; a series of commands exactly as they would be +; entered from a CP/M Console. The SUBMIT Command +; (or SUB Command) reads this files and transforms +; it for processing by the ZCPR (the $$$.SUB File). +; ZCPR will then execute the commands indicated +; EXACTLY as if they were typed at the Console." +; Hence, to permit this to happen, the $$$.SUB file must always +; be present on a specific drive, and A: is the choice for said drive. +; With this facility engaged as such, Indirect Command Files like: +; DIR +; A: +; DIR +; can be executed, even though the currently logged-in drive is changed +; during execution. If the $$$.SUB file was present on the currently +; logged-in drive, the above series of commands would not work since the +; ZCPR would be looking for $$$.SUB on the logged-in drive, and switching +; logged-in drives without moving the $$$.SUB file as well would cause +; processing to abort. +; +SUBA equ TRUE ; Set to TRUE to have $$$.SUB always on A: + ; Set to FALSE to have $$$.SUB on the logged-in drive +; +; The following flag enables extended processing for user-program supplied +; command lines. This is for Command Level 3 of ZCPR. Under the CCPZ Version +; 4.0 philosophy, three command levels exist: +; (1) that command issued by the user from his console at the '>' prompt +; (2) that command issued by a $$$.SUB file at the '$' prompt +; (3) that command issued by a user program by placing the command into +; CIBUFF and setting the character count in CBUFF +; Setting CLEVEL3 to TRUE enables extended processing of the third level of +; ZCPR command. All the user program need do is to store the command line and +; set the character count; ZCPR will initialize the pointers properly, store +; the ending zero properly, and capitalize the command line for processing. +; Once the command line is properly stored, the user executes the command line +; by reentering the ZCPR through CPRLOC [NOTE: The C register MUST contain +; a valid User/Disk Flag (see location 4) at this time.] +; +CLEVEL3 equ TRUE ;ENABLE COMMAND LEVEL 3 PROCESSING +; +; +;*** TERMINAL AND 'TYPE' CUSTOMIZATION EQUATES +; +NLINES EQU 24 ;NUMBER OF LINES ON CRT SCREEN +WIDE EQU TRUE ;TRUE IF WIDE DIR DISPLAY +FENCE EQU '|' ;SEP CHAR BETWEEN DIR FILES +; +PGDFLT EQU TRUE ;SET TO FALSE TO DISABLE PAGING BY DEFAULT +PGDFLG EQU 'P' ;FOR TYPE COMMAND: PAGE OR NOT (DEP ON PGDFLT) + ; THIS FLAG REVERSES THE DEFAULT EFFECT +; +MAXUSR EQU 15 ;MAXIMUM USER NUMBER ACCESSABLE +; +SYSFLG EQU 'A' ;FOR DIR COMMAND: LIST $SYS AND $DIR +; +SOFLG EQU 'S' ;FOR DIR COMMAND: LIST $SYS FILES ONLY +; +SUPRES EQU TRUE ;SUPRESSES USER # REPORT FOR USER 0 +; +DEFUSR EQU 0 ;DEFAULT USER NUMBER FOR COM FILES +; +SPRMPT EQU '$' ;CPR PROMPT INDICATING SUBMIT COMMAND +CPRMPT EQU '>' ;CPR PROMPT INDICATING USER COMMAND +; +NUMBASE EQU 'H' ;CHARACTER USED TO SWITCH FROM DEFAULT + ; NUMBER BASE +; +SECTFLG EQU 'S' ;OPTION CHAR FOR SAVE COMMAND TO SAVE SECTORS +; +; END OF CUSTOMIZATION SECTION +; +CR EQU 0DH +LF EQU 0AH +TAB EQU 09H +; +WBOOT EQU BASE+0000H ;CP/M WARM BOOT ADDRESS +UDFLAG EQU BASE+0004H ;USER NUM IN HIGH NYBBLE, DISK IN LOW +BDOS EQU BASE+0005H ;BDOS FUNCTION CALL ENTRY PT +TFCB EQU BASE+005CH ;DEFAULT FCB BUFFER +TBUFF EQU BASE+0080H ;DEFAULT DISK I/O BUFFER +TPA EQU BASE+0100H ;BASE OF TPA +; +; WW - MOVED MACROS BELOW TO ADDINSTR'S IN WRAPPER +; +;; +;; +;; MACROS TO PROVIDE Z80 EXTENSIONS +;; MACROS INCLUDE: +;; +;$-MACRO ;FIRST TURN OFF THE EXPANSIONS +;; +;; JR - JUMP RELATIVE +;; JRC - JUMP RELATIVE IF CARRY +;; JRNC - JUMP RELATIVE IF NO CARRY +;; JRZ - JUMP RELATIVE IF ZERO +;; JRNZ - JUMP RELATIVE IF NO ZERO +;; DJNZ - DECREMENT B AND JUMP RELATIVE IF NO ZERO +;; LDIR - MOV @HL TO @DE FOR COUNT IN BC +;; LXXD - LOAD DOUBLE REG DIRECT +;; SXXD - STORE DOUBLE REG DIRECT +;; +;; +;; +;; @GENDD MACRO USED FOR CHECKING AND GENERATING +;; 8-BIT JUMP RELATIVE DISPLACEMENTS +;; +;@GENDD MACRO ?DD ;;USED FOR CHECKING RANGE OF 8-BIT DISPLACEMENTS +; IF (?DD GT 7FH) AND (?DD LT 0FF80H) +; DB 100H ;Displacement Range Error on Jump Relative +; ELSE +; DB ?DD +; ENDIF +; ENDM +;; +;; +;; Z80 MACRO EXTENSIONS +;; +;JR MACRO ?N ;;JUMP RELATIVE +; DB 18H +; @GENDD ?N-$-1 +; ENDM +;; +;JRC MACRO ?N ;;JUMP RELATIVE ON CARRY +; DB 38H +; @GENDD ?N-$-1 +; ENDM +;; +;JRNC MACRO ?N ;;JUMP RELATIVE ON NO CARRY +; DB 30H +; @GENDD ?N-$-1 +; ENDM +;; +;JRZ MACRO ?N ;;JUMP RELATIVE ON ZERO +; DB 28H +; @GENDD ?N-$-1 +; ENDM +;; +;JRNZ MACRO ?N ;;JUMP RELATIVE ON NO ZERO +; DB 20H +; @GENDD ?N-$-1 +; ENDM +;; +;DJNZ MACRO ?N ;;DECREMENT B AND JUMP RELATIVE ON NO ZERO +; DB 10H +; @GENDD ?N-$-1 +; ENDM +;; +;LDIR MACRO ;;LDIR +; DB 0EDH,0B0H +; ENDM +;; +;LDED MACRO ?N ;;LOAD DE DIRECT +; DB 0EDH,05BH +; DW ?N +; ENDM +;; +;LBCD MACRO ?N ;;LOAD BC DIRECT +; DB 0EDH,4BH +; DW ?N +; ENDM +;; +;SDED MACRO ?N ;;STORE DE DIRECT +; DB 0EDH,53H +; DW ?N +; ENDM +;; +;SBCD MACRO ?N ;;STORE BC DIRECT +; DB 0EDH,43H +; DW ?N +; ENDM +;; +;; END OF Z80 MACRO EXTENSIONS +; +; +;**** Section 0 **** +; + ORG CPRLOC +; +; ENTRY POINTS INTO ZCPR +; If the ZCPR is entered at location CPRLOC (at the JMP to CPR), then +; the default command in CIBUFF will be processed.

Under the original CPR, it was necessary to initialize +; the pointer after the reserved space for the command buffer to point to +; the first byte of the command buffer. Under Version 4.x of ZCPR, this is +; no longer the case. The CIBPTR (Command Input Buffer PoinTeR) is located +; to be compatable with such programs (provided they determine the buffer +; length from the byte at MBUFF [CPRLOC + 6]), but under Version 4.x of ZCPR +; this is no longer necessary.

This command line +; is generated in one of three ways: +; (1) by the user entering it through the BDOS READLN function at +; the du> prompt [user input from keyboard] +; (2) by the SUBMIT File Facility placing it there from a $$$.SUB +; file +; (3) by an external program or user placing the required command +; into this buffer +; In all cases, the command line is placed into the buffer starting at +; CIBUFF. This command line is terminated by the last character (NOT Carriage +; Return), and a character count of all characters in the command line +; up to and including the last character is placed into location CBUFF +; (immediately before the command line at CIBUFF). The placed command line +; is then parsed, interpreted, and the indicated command is executed. +; If CLEVEL3 is permitted, a terminating zero is placed after the command +; (otherwise the user program has to place this zero) and the CIBPTR is +; properly initialized (otherwise the user program has to init this ptr). +; If the command is placed by a user program, entering at CPRLOC is enough +; to have the command processed. Again, under CCPZ Version 4.0, it is not +; necessary to store the pointer to CIBUFF in CIBPTR; ZCPR will do this for +; the calling program if CLEVEL3 is made TRUE. +; WARNING: The command line must NOT exceed BUFLEN characters in length. +; For user programs which load this command, the value of BUFLEN can be +; obtained by examining the byte at MBUFF (CPRLOC + 6). +; +BUFLEN EQU 80 ;MAXIMUM BUFFER LENGTH +MBUFF: + DB BUFLEN ;MAXIMUM BUFFER LENGTH +CBUFF: + DB 0 ;NUMBER OF VALID CHARS IN COMMAND LINE +CIBUFF: + DB " " ;DEFAULT (COLD BOOT) COMMAND +CIBUF: + DB 0 ;COMMAND STRING TERMINATOR + DS BUFLEN-($-CIBUFF)+1 ;TOTAL IS 'BUFLEN' BYTES +; +CIBPTR: + DW CIBUFF ;POINTER TO COMMAND INPUT BUFFER +CIPTR: + DW CIBUF ;CURRENT POINTER +; + DS 26 ;STACK AREA +STACK EQU $ ;TOP OF STACK +; +; FILE TYPE FOR COMMAND +; +COMMSG: + DB "COM" +; +; SUBMIT FILE CONTROL BLOCK +; +SUBFCB: + IF SUBA ;IF $$$.SUB ON A: + DB 1 ;DISK NAME SET TO DEFAULT TO DRIVE A: + ENDIF +; + IF ~SUBA ;IF $$$.SUB ON CURRENT DRIVE + DB 0 ;DISK NAME SET TO DEFAULT TO CURRENT DRIVE + ENDIF +; + DB "$$$" ;FILE NAME + DB " " + DB "SUB" ;FILE TYPE + DB 0 ;EXTENT NUMBER + DB 0 ;S1 +SUBFS2: + DS 1 ;S2 +SUBFRC: + DS 1 ;RECORD COUNT + DS 16 ;DISK GROUP MAP +SUBFCR: + DS 1 ;CURRENT RECORD NUMBER +; +; COMMAND FILE CONTROL BLOCK +; +FCBDN: + DS 1 ;DISK NAME +FCBFN: + DS 8 ;FILE NAME +FCBFT: + DS 3 ;FILE TYPE + DS 1 ;EXTENT NUMBER + DS 2 ;S1 AND S2 + DS 1 ;RECORD COUNT +FCBDM: + DS 16 ;DISK GROUP MAP +FCBCR: + DS 1 ;CURRENT RECORD NUMBER +; +; OTHER BUFFERS +; +PAGCNT: + DB NLINES-2 ;LINES LEFT ON PAGE +CHRCNT: + DB 0 ;CHAR COUNT FOR TYPE +QMCNT: + DB 0 ;QUESTION MARK COUNT FOR FCB TOKEN SCANNER +; +; CPR BUILT-IN COMMAND TABLE +; +NCHARS EQU 4 ;NUMBER OF CHARS/COMMAND +; +; CPR COMMAND NAME TABLE +; EACH TABLE ENTRY IS COMPOSED OF THE 4-BYTE COMMAND AND 2-BYTE ADDRESS +; +CMDTBL: + DB "DIR " + DW DIR + DB "LIST" + DW LIST + DB "TYPE" + DW TYPE + DB "USER" + DW USER + DB "DFU " + DW DFU +; + IF ~RAS ;FOR NON-RAS + DB "GO " + DW GO + DB "ERA " + DW ERA + DB "SAVE" + DW SAVE + DB "REN " + DW REN + DB "GET " + DW GET + DB "JUMP" + DW JUMP + ENDIF +; +NCMNDS EQU ($-CMDTBL)/(NCHARS+2) +; +; +;**** Section 2 **** +; CPR STARTING POINTS +; +; START CPR AND DON'T PROCESS DEFAULT COMMAND STORED +; +CPR1: + XRA A ;SET NO DEFAULT COMMAND + STA CBUFF +; +; START CPR AND POSSIBLY PROCESS DEFAULT COMMAND +; +; NOTE ON MODIFICATION BY RGF: BDOS RETURNS 0FFH IN +; ACCUMULATOR WHENEVER IT LOGS IN A DIRECTORY, IF ANY +; FILE NAME CONTAINS A '$' IN IT.

In order to provide time/date support for as many systems as possible, +; a set of universal routines are used. These routines do not do the +; actual stamping, but provide all the data required to method specific +; programs to perform the needed services. To use the DOS services, the +; external handler needs to tie itself into the Time/Date vector table +; in the ZSDOS configuration area. The Get Stamp, Put Stamp, Stamp Last +; Access, Stamp Create, and Stamp Modify routines receive the following +; parameters in the Z80 registers: +; A = Offset to DIR entry [0,20H,40H,60H] +; BC = Address of ZSDOS WRFCB routine +; DE = Pointer to Directory Buffer +; HL = DMA address +; IX = Pointer to FCB passed to DOS +; The directory buffer contains the dir entry for the FCB passed to DOS, +; A contains the offset. The disk has been tested for R/O on all calls +; except get stamp and is R/W. If a CP/M+ style stamping is used, a simple +; call to the address passed in BC is used to update the disk after adding +; the time as required. This call is ALWAYS required. The routines may +; use AF,BC,DE, and HL without restoring them. Four levels of stack are +; available on the DOS stack for use by the functions.

These instruc +tions cite the relevant paragraphs in the manual in case a more +detailed description is desired. + +1 LOADINÇ THĊ DOS These steps are written around the full- +featured ZSDOS version of the Operating System to demonstrate all +of the power, and provide procedures for systems already using +either type of Time Stamping supported by ZSDOS. It is recom +mended that these steps be followed initially, followed by a +later installation with ZDDOS if either a minimal memory configu +ration is desired, or only DateStamper-type File Stamping is +desired. The differences between ZSDOS and ZDDOS are briefly +described in Section 1 of the manual. + + A. DO YOU OPERATE UNDER NZ-COM?

You will probably want to tailor the +stamping to your system clock or other parameters now, so please +read Section 3 of the manual for details. + + +3. FINAL TOUCHES. After you have completed whichever of the above +steps you elected, we recommend highly that you read at least +Sections 1 and 2 of the manual to learn the power that ZSDOS can +bring to 8-bit computers. Learn to use the tools provided with +the ZSDOS distribution package to customize the Operating System +to your own requirements and desires. All tools listed below +operate equally well under ZSDOS and ZDDOS unless specifically +noted. Briefly, the tools are: + + + COPY - Copy single or groups of files between disk drives +and/or user areas preserving date/time stamps (Modification of +ZCPR tool MCOPY). (4.1) + + DATSWEEP (ZDDOS or ZSDOS with DateStamper only) - +Plu*Perfect's full-featured screen-oriented disk and file utility +(4.2). + + FILEATTR - Display/Set attributes of individual or groups of +files. (4.3) + + FILEDATE (ZDDOS or ZSDOS with DateStamper only) - Full fea +tured Disk directory lister that permits elaborate selective +listing based on DateStamper-style Date/Time files. (4.4) + + INITDIR - Initialize a disk directory for P2DOS (CP/M Plus) +type Date/Time Stamping. (3.2.5) + + PUTDS - Initialize a disk for DateStamper type Date/Time +Stamping (licensed Plu*Perfect utility). (3.2.4) + + RELOG - Resets Hard Disk Login vectors. Primarily for use +in more elaborate Hard Disk systems which swap logical Hard +Drives, or use removeable-media, but are defined as Fixed Drives. +(4.5) + + TD - Display/Set an installed clock via ZSDOS/ZDDOS. (4.6) + + ZCAL - Display a brief calendar of current or any desired +month. (4.7) + + ZCNFG - Configuration utility to set defaults, such as US or +European date displays, in COPY, FILEATTR, FILEDATE, TD, and ZXD. + + ZPATH (ZSDOS only) - Permits setting the Internal DOS path +as well as a ZCPR3 path (Modification of ZCPR tool PATH). (4.9) + + ZSCONFIG - Basic configuration program for both ZSDOS and +ZDDOS.

+ ZSVSTAMP is a utility program that saves the create +date/time stamp of a given file in memory. At a later time, +ZSVSTAMP can restore the create stamp to a file. This can be +useful when modifying a file with an editor that actually creates +a new copy of the file rather than modifying it in place. +ZSVSTAMP allows the original creation date of the document to be +retained. + + In order to support all types of date stamping under ZSDOS, +ZSVSTAMP uses the get/set stamp functions of ZSDOS (or ZDDOS) and +thus may only be run under these operating systems. It also +requires ZCPR3 with multiple command line, external FCB and +message buffer. If an attempt is made to run ZSVSTAMP on a +system that does not meet these requirements, the program will +abort with an error message. + + + +2.0 OPERATION + + ZSVSTAMP has two modes of operation -- Manual and Automatic. + + + +2.1 Automatic Mode + + This mode is the most commonly used. It is extremely well +suited for use in alias scripts and can make the whole process of +saving and restoring date stamps virtually transparent to the +user. The syntax is: + + ZSVSTAMP approg [ufn] + +where "approg" is the program, such as an editor, that you wish +to run and "ufn" is an unambiguous file name to be modified by +"approg." When a command of this type is given, ZSVSTAMP saves +"ufn"'s creation date in protected memory. It then causes +"approg" to be run, and when "approg" finishes, ZSVSTAMP is +automatically run again to restore the original create stamp to +"ufn." If "ufn" does not exist, or if the disk does not support +date stamping, ZSVSTAMP displays a warning message and +immediately passes control to "approg" without attempting to save +a stamp. In this situation, ZSVSTAMP is not rerun when "approg" +completes execution. + + Some editors allow a syntax such as + + EDIT oldfile newfile + +When ZSVSTAMP is invoked with more than one parameter following +the application name, no stamps are saved or restored. This +feature can be disabled if desired, (see the section on +customization). + + + +2.2 Manual Mode + + Manual mode can be used to save or restore a file's create +stamp. The syntax is: + + ZSVSTAMP ufn /G or /S + +to Get or Save a file's create stamp, or: + + ZSVSTAMP ufn /P or /R + +to Put or Restore a saved stamp back onto a file. + + + +3.0 CUSTOMIZING ZSVSTAMP + +There are five configuration flags located near the beginning of +the program. Each flag is preceeded by an ASCII string to help +identify its function. These flags may be patched to customize +ZSVSTAMP as desired. + + The first four flags determine whether or not various +warning messages can be displayed when ZSVSTAMP is being run in +Automatic Mode. Setting a flag to 0 disables its associated +message; any other value enables the message. The flags are +labeled "NOSTMP," "NOFILE," "READERR," and "UPDTERR," and they +affect the "Disk has no time/date stamps," "File not found," +"Can't read time/date stamp," and "Can't update time/date stamp" +messages respectively. The program is distributed with all four +messages enabled. Please note that these flags have no effect in +Manual Mode where error messages are always enabled. + + The fifth and final configuration flag is labeled +"REPLALWS." It determines what ZSVSTAMP will do when more than +one parameter follows the application name in an Automatic Mode +command. If the byte following the "REPLALWS" label equals 0, +ZSVSTAMP checks to see if there is more than one parameter +following the application program name.

An annotated summary is +provided directly below especially for expert users followed by annotated +details. + +Please review the other documentation and source code that comes with +cpmtools for more information about cpmtools. Please review the cygwin +documentation for more information about cygwin. + +At time of this writing, I have used the latest versions of the packages +listed above to build the latest version of cpmtools in its entirety. I have +documented the steps I followed below. + +Although there are probably other environments and compilers that can build +cpmtools for Windows I have not been successful in using the other several I +tried. Using a complete cygwin installation I had no problems and I had +cpmtools built in moments after I had cygwin installed and the cpmtools +source in place as documented below. + +Intended Audience +----------------- + +This document takes two tracks for installing cpmtools binary executables +after they have been built in cygwin: + +1. End users who will run cpmtools from within the cygwin shell. This +includes unix users who do not want to use the native Windows command line. + +2. End users who will run cpmtools from the native Windows command line. The +average Windows user does not have cygwin, and probably won't want to install +cygwin or learn a unix-like shell to use cpmtools. + +The consideration here is where cpmtools looks for its CP/M disk format +definitions file (diskdefs) when not in a unix-like environment like cygwin +and this consideration will affect the way you build cpmtools since this path +is hardcoded into the binary executables. + +My hope is that this document will help address the needs of both types of +Windows end users and those who wish to provide cpmtools to them. + +Summary +------- + +- Install cygwin with ncurses. +- Download cpmtools-2.9.tar.tar to your cygwin home directory. +- Start cygwin from the shortcut on the Windows desktop. + +- Enter the following commands: + +tar -xvf cpmtools.tar.tar +cd cpmtools-2.9 +./configure --with-diskdefs=/usr/local/share/diskdefs +make +mkdir /usr/local/share +mkdir /usr/local/share/man +mkdir /usr/local/share/man/man1 +mkdir /usr/local/share/man/man5 +make install + +Assumptions +----------- + +The above builds cpmtools under cygwin for end users who will use cpmtools in +the cygwin shell and who will use the default installation. + +I am assuming in this summary that all has gone well and that anyone who +deviates from what I have done or who has customized their cygwin +installation will be able to troubleshoot their own problems, + +I therefore make the following related assumptions in this summary: + +- That compiler related programs and libraries required to build cpmtools +under cygwin (including ncurses) are installed. + +- That you wish to download into and work under your home directory. You may +also consider whether a better place to download is in /usr/local/src and +whether you should install in the binaries in /opt/cpmtools/ and things of +that nature. + +Default Format +-------------- + +You can change the default format to accomodate the special needs of your +users so they don't need to type their favorite format. The following line +can be entered to configure for an apple-do default format: + +./configure --with-defformat="apple-do" --with-diskdefs=/usr/local/share/diskdefs + +Native Windows Installation +--------------------------- + +If you wish to distribute your binaries to Windows end users who will not +have the cygwin shell and who will use the Windows command line, you have 2 +options: + +1. Require your users to always work in the same directory as diskdefs. + +- or - + +2. Hardcode the default diskdefs path into your binary executables and +require your users to always use the expected directory for diskdefs. + +The following line shows how to configure for an apple-do default format and +to set the default diskdefs path in a mannner that is acceptable to Windows +to a relative path from the root of the current drive: + +./configure --with-defformat="apple-do" --with-diskdefs=/cpmtools/diskdefs + +Cross-Cygwin Binary Installation +-------------------------------- + +You can still use the binaries built as above and installed using "make +install" in cygwin if you add the following line to /etc/fstab (assuming your +cygdrive is the Windows C:drive): + +c:\cygwin\usr\local\share /cpmtools + +Making a Zip Installation for Native Windows Users +-------------------------------------------------- + +If your target is the Windows user who does not have cygwin you can do the +following in cygwin in your build directory to create a zip file that will +contain the cpmtools binary executables: + +- mkdir cpmtools +- cp *.exe cpmtools/. +- cp diskdefs cpmtools/. +- cp /bin/cygwin1.dll cpmtools/. +- cp /bin/cygncurses-8.dll cpmtools/. +- zip -R cpmtools/*.* + +Making Documentation for Native Windows Users +--------------------------------------------- + +If you wish to provide the cpmtools manual pages in html format you can use +man2html to generate your html in ugly format and redirect to a file and edit +by hand. Here's an example: + +man2html -r cpm.5 > cpm.html + +If you wish to avoid html and provide the cpmtools manual pages in text +format you can use troff to generate your text in ugly format and redirect to +a file and edit by hand. Here's an example: + +troff -a cpm.5 > cpm.txt + +This concludes the summary. + +Details, Alternatives, and Other Fluff +-------------------------------------- + +1.cygwin +-------- + +Cygwin gave me a complete and free environment to both configure and build +cpmtools in its entirety. + +I installed cygwin from http://www.cygwin.com/ in its entirety which included +the ncurses library and when prompted to select a download site I chose +ftp://mirrors.kernel.org/sourceware/cygwin/ + +The site you pick will depend on your own preference and how much of cygwin +you decide to install will be up to you. I have a good Internet connection +and a large hard disk so installing ALL of cygwin was no problem for me. +Those who don't may wish to attempt an incremental installation which I +personally found to be annoying and tedious. + +It is not necessary to install ALL cygwin options. Another alternative is to +take the minimalistic approach and just install the compiler related +programs and libraries required to build cpmtools (including ncurses). If you +have missed something you will still be able to select additional components +via Cygwin Setup. + +By default cygwin installs into c:\cygwin and puts a shortcut on the Windows +desktop. By default the cygwin shell starts in your cygwin home directory +under c:\cygwin\home\. I used the cygwin default paths for my installation of +cygwin. + +2. cpmtoools +------------ + +I then downloaded Download cpmtools-2.9 from +http://www.moria.de/~michael/cpmtools/ +and used WinRAR to extract cpmtools-2.9 to +C:\cygwin\home\bbuckels\cpmtools-2.9\ + +I have noted in the summary that tar can be used. Use whatever you are +comfortable with to handle things from unix of a tarball nature. + +3. Building +----------- + +3.1. I started cygwin by clicking on the cygwin shortcut on my desktop which +placed me into my cygwin home directory in the cygwin shell. + +3.2 Now in the cygwin shell, I changed to the cpmtools directory by typing +the following and pressing the [Enter] key: + +cd cpmtools-2.9 + + +3.3 Running the configure script +-------------------------------- + +Before making cpmtools, the configure script must be run to create the +cpmtools makefile and the config.h header file required by cpmtools. + +I ran the configure script with two options; to set the default format for +cpmtools to Apple II DOS 3.3 disk images and to tell cpmtools where to find +the diskdefs format definitions file (which is required to run cpmtools. See +far below.) + +3.3.2 Building for use in the cygwin shell +------------------------------------------ + +If I was building for use in the cygwin shell and I was using the default +paths used by "make install" noted far below, to be certain that my diskdefs +file would be found and to set my default format to "apple-do" I would type +the following and press the [Enter] key: + +./configure --with-defformat="apple-do" --with-diskdefs=/usr/local/share/diskdefs + +3.3.1 Building for the Native Windows command line +--------------------------------------------------- + +To set the default format to "apple-do" and to provide a relative path for +native Windows to my diskefs file which I would later copy to C:\cpmtools\ , +I typed the following and pressed the [Enter] key: + +./configure --with-defformat="apple-do" --with-diskdefs=/cpmtools/diskdefs + +Note: Windows paths are typed into the Windows native command line with +backslashes in the MS- DOS tradition. Historically the forward slash used by +unix as a path separator was used as a switch character in MS-DOS utilities +and this has carried forward with the commands that come with Windows. But in +a program, local Windows paths can be used with forward slashes instead and +they still work. Backslashes will cause problems for configure so use forward +slashes. + +3.4. The configure script created my cpmtools makefile and config.h with the +options I chose. I then ran make by typing the following and pressing the +[Enter] Key. + +make + +This concludes the first part of the details section of this document and I +have covered the basic steps that I followed to build cpmtools. What you do +will likely be a close variation. + +4. Installing +------------- + +4.1 Some of this is also noted in the summary. Also keep in mind that if +cpmtools is used outside of cygwin access to the documentation which is in +the form of unix-style man pages will not be available unless reformatted to +a media type that Windows users are familiar with. + +4.1.1 Installing for the cygwin shell +----------------------------------- + +You can review the summary and the cpmtools INSTALL document for more +information on unix-like installations. Installation of cpmtools for use in +the cygwin shell follows those conventions. + +If installing cpmtools to be used in cygwin using the cpmtools defaults and +assuming the directories below don't already exist, you will need to manually +create the following directories using the mkdir command as follows: + +mkdir /usr/local/share +mkdir /usr/local/share/man +mkdir /usr/local/share/man/man1 +mkdir /usr/local/share/man/man5 + +This is because the manual pages (man pages) will not be installed if you +don't. If you install the man pages, then when you need help on cpmtools in +cygwin, you can just enter "man cpmls" or "man cpmchmod", etc. + +After you make the directories above enter the following command: + +make install + +Assuming all has gone well, cpmtools is now part of your cygwin installation +and can be used wherever you work in cygwin. + +4.1.2 Installing for Use Outside Cygwin +--------------------------------------- + +Please also read the summary. + +The requirements of my installation were to create a directory structure for +a binary executable version of cpmtools targetted at Apple II disk image +users that would run at the native Windows cmd prompt. I offer the following +for general reference. The cygwin paths are based on my installation of +cygwin and are presented using conventional windows pathname notation. + +4.1.2.1 Dll's +------------- + +Two dll's from the c:\cygwin\bin\ directory were required: + +cygwin1.dll +cygncurses-8.dll + +Regardless of installation, for this cygwin and this ncurses version access +to these dll's will be required by this version of the cpmtools excecutables. + +4.2 Manually Placing Files for Use Outside Cygwin +------------------------------------------------- + +I did my installation by hand. + +My executables were created in c:\cygwin\home\bbuckels\cpmtools-2.9\ (my +cygwin home directory) which is also where the diskdefs file was. + +I used Windows Explorer to manually do the following: + +4.2.1 create c:\cpmtools\ directory. +4.2.2 copy all 8 exes into c:\cpmtools\ +4.2.3 copy both dll's listed above into c:\cpmtools\ +4.2.4 copy diskdefs into c:\cpmtools\ + +This gave me my directory structure and files for testing and distribution. + +I also placed an Apple II CP/M disk image called EXMPLCPM.dsk in c:\cpmtools\ +as a test target. + + +5. Additional Notes +------------------- + +5.1 diskdefs - CP/M disk format definitions +-------------------------------------------- + +The diskdefs file is a plain ascii text file that serves as a database of +disk and disk image format definitions. It can be reviewed for available CP/M +formats and their names. For Apple II CP/M 80 users the disk image formats +apple-do and apple-po are available. + +The possible locations where cpmtools first looks for the diskdefs file: + +- Can vary depending on the preferences of the person who builds the cpmtools +binaries (executables) from the source code. + +- The location is also installation dependent and the diskdefs file may also +have been renamed (but we hope not). + +If it's not found the current (work) directory is then searched for a file +called diskdefs. + +On a unix-like system, a ${prefix}/share/ style path like /usr/local/share/ +is a possible place that cpmtools could be made to first look for diskdefs. + +In a Win32 system sometimes unix-like shells like cygwin are used to run +cpmtools instead of Windows cmd. For those installations unix-like +conventions probably should apply. + +For cpmtools installations targetted at the average Windows user who does not +have a unix-like shell and uses the Windows cmd prompt to run cpmtools there +is no standard shared place that cpmtools can be made to first look for +diskdefs. Pathed File names like \cpm\diskdefs or even c:\cpmtools\diskdefs +are possible. + +5.2 Difficulties in using the Windows File System +--------------------------------------------------- + +This is not a troubleshooting guide. Unless you wish to find-out for yourself +as I did just how many problems you can face with all of this, or you are +really an expert, please do yourself a favour and try to stay within what I +am suggesting as standard or alternative ways of building cpmtools. + +Missing libaries and compiler tools can be solved by trial and error and +reading the cygwin and cpmtools documentation. + +There are however some things about path names and file names that you need +to be aware of, some of which I have mentioned throughout this document and +some which I deliberately did not mention yet, like avoiding absolute paths +and drive letters. + +If you use a drive letter like C: when hardcoding a path to diskdefs you are +making several assumptions: + +First off, you are assuming that your build of cpmtools will only be run from +within Windows cmd shell on the local drive C:, (not from a bash-like shell +like cygwin which doesn't support drive letters the same way Windows cmd and +Windows itself does), and that diskdefs will not be on another drive, and +that drive C: exists in the first place, and that diskdefs is not on a +Windows network either unless drive C:,X:,Y:,Z:,etc is a mapped network +drive. It is questionable whether cpmtools build process for diskdefs pathing +supports UNC pathing anyway. I couldn't get \\ to work since the first slash +disappears in the configure script and the second slash becomes an escape +sequence for the next letter. + +Relative pathing will work and if you want to use conventions like +/cpmtools-2.9/diskedefs this will work. Environments like ${USERPROFILE} +aren't a good idea even if I could have got them to work since they are not +portable for several reasons and I will say no more on this except I +recommend that any path that you decide to use for diskdefs will only be +almost portable between shells if off the root directory and contains forward +slashes and no drive letters or colons. + +I hope what I have said proved less confusing to read than to write if you +have bothered to read it. If you are not confused yet read further. + +- Since cpmtools has special meanings for A: and B: as command line targets +it probably isn't a good idea to use these drives especially. + +- Some programmers and users have no difficulty in shifts between unix-like +and Windows pathing. Some will be familiar with how colons are used on +systems like Mac OSX. I think the only point to be made here is to consider +your target audience and all the things you can anticipate going wrong with +interoperability of all of this, (cpmtools being a set of command line +tools), and build cpmtools accordingly for the needs of you or your users, +then test what you have built with all this in mind. + +5.3 Testing your build of cpmtools +---------------------------------- + +To test what you have built I suggest you start with cpmls and cpmcp and an +apple disk image or equivalent. + +John Elliot said "If you have appropriate rights, the CPMTOOLS should be able +to access the floppy drive by using "A:" or "B:" as the name of the disc +image.". I say don't bother mucking with your physical disk drive unless you +have a physical CP/M disk of a format supported by cpmtools safely in the +drive. + +Get an apple CP/M disk image and use it for testing is what I suggest. The +following examples assume you have an Apple II DOS 3.3 order disk image +called EXMPLCPM.dsk for testing. + +To list the files: + +cpmls -f apple-do EXMPLCPM.dsk + +The following example shows how to copy a file from an Apple II DOS 3.3 order +cpm disk image to the current directory: + +cpmcp -f apple-do EXMPLCPM.dsk bhead.c 0:bhead.c + +The following example shows how to copy a file to an Apple II DOS 3.3 order +cpm disk image from the current directory: + +cpmcp -f apple-do EXMPLCPM.dsk 0:bhead.c bhead.c + +To test the other utilities in cpmtools like cpmrm, cpmchattr, cpmchmod, +fsck.cpm and fsed.cpm, review the appropriate manpages for usage. + +Those are simple tests as well using an apple-do format disk image. For +mkfs.cpm I will leave it to those more capable than I to decide what to do +there.

At this point in time my focus is also on Apple II Z80 Softcard +users. Thankfully Michael Haardt has considered Apple II disk images in +cpmtools.

+ +  +NAME cpm - CP/M disk and file system format.

+ +  +DESCRIPTION

+ +  +Characteristic sizes - Each CP/M disk format is described by the following specific sizes: +
+ +
+ +Sector size in bytes +
+ +Number of tracks +
+ +Number of sectors +
+ +Block size +
+ +Number of directory entries +
+ +Logical sector skew +
+ +Number of reserved system tracks +

+
+ +A block is the smallest allocatable storage unit. CP/M supports block +sizes of 1024, 2048, 4096, 8192 and 16384 bytes. Unfortunately, this +format specification is not stored on the disk and there are lots of +formats. Accessing a block is performed by accessing its sectors, which +are stored with the given software skew. +

+ +  +Device areas - A CP/M disk contains three areas:
+ +
+ +System tracks (optional) +
+ +Directory +
+ +Data +

+
+ +The system tracks store the boot loader and CP/M itself. In order to save +disk space, there are non-bootable formats which omit those system tracks. +The term disk capacity always excludes the space for system tracks. +Note that there is no bitmap or list for free blocks. When accessing a +drive for the first time, CP/M builds this bitmap in core from the directory. +

+ +  +Directory entries - The directory is a sequence of directory entries (also called extents), +which contain 32 bytes of the following structure:
+
+ +St F0 F1 F2 F3 F4 F5 F6 F7 E0 E1 E2 Xl Bc Xh Rc
+
+ +Al   Al Al Al Al Al Al Al Al Al Al Al Al Al AlAl
+
+
+ + +St is the status; possible values are:
+
+ +0-15: used for file, status is the user number +
+ +16-31: used for file, status is the user number (P2DOS) +or used for password extent (CP/M 3 or higher) +
+ +32: disc label +
+ +33: time stamp (P2DOS) +
+ +0xE5: unused +

+
+ +F0-E2 are the file name and its extension. They may consist of +any printable 7 bit ASCII character but: < > . , ; : = ? * [ ]. +The file name must not be empty, the extension may be empty. Both are +padded with blanks. The highest bit of each character of the file name +and extension is used as attribute. The attributes have the following +meaning:
+ + +
+F0: requires set wheel byte (Backgrounder II) +
+ +F1: public file (P2DOS, ZSDOS), forground-only command (Backgrounder II) +
+ +F2: date stamp (ZSDOS), background-only commands (Backgrounder II) +
+ +F7: wheel protect (ZSDOS) +
+ +E0: read-only +
+ +E1: system file +
+ +E2: archived +

+
+ +Public files (visible under each user number) are not supported by CP/M +2.2, but there is a patch and some free CP/M clones support them without +any patches. +

+ +The wheel byte is (by default) the memory location at 0x4b. If it is +zero, only non-privileged commands may be executed. + +

+ + +Xl and Xh store the extent number. A file may use more than +one directory entry, if it contains more blocks than an extent can hold. +In this case, more extents are allocated and each of them is numbered +sequentially with an extent number. If a physical extent stores more than +16k, it is considered to contain multiple logical extents, each pointing +to 16k data, and the extent number of the last used logical extent +is stored. Note: Some formats decided to always store only one logical +extent in a physical extent, thus wasting extent space. CP/M 2.2 allows +512 extents per file, CP/M 3 and higher allow up to 2048. Bit 5-7 of +Xl are 0, bit 0-4 store the lower bits of the extent number. Bit 6 +and 7 of Xh are 0, bit 0-5 store the higher bits of the extent number. + +

+ + +Rc and Bc determine the length of the data used by this extent. The +physical extent is divided into logical extents, each of them being 16k +in size (a physical extent must hold at least one logical extent, e.g. a +blocksize of 1024 byte with two-byte block pointers is not allowed). +Rc stores the number of 128 byte records of the last used logical extent. +Bc stores the number of bytes in the last used record. The value 0 means +128 for backward compatibility with CP/M 2.2, which did not support Bc. + +

+ + +Al stores block pointers. If the disk capacity is less than 256 blocks, +Al is interpreted as 16 byte-values, otherwise as 8 double-byte-values. +A block pointer of 0 marks a hole in the file. If a hole +covers the range of a full extent, the extent will not be allocated. In particular, +the first extent of a file does not neccessarily have extent number 0. +A file may not share blocks with other files, as its blocks would be freed +if the other files is erased without a following disk system reset. CP/M returns +EOF when it reaches a hole, whereas UNIX returns zero-value bytes, which makes +holes invisible. +

+ +  +Time stamps - P2DOS and CP/M Plus support time stamps, which are stored in each fourth +directory entry. +

+This entry contains the time stamps for +the extents using the previous three directory entries. Note that you +really have time stamps for each extent, no matter if it is the first +extent of a file or not. The structure of time stamp entries is:
+ +
+ +1 byte status 0x21 +
+ +8 bytes time stamp for third-last directory entry +
+ +2 bytes unused +
+ +8 bytes time stamp for second-last directory entry +
+ +2 bytes unused +
+ +8 bytes time stamp for last directory entry +

+
+ +A time stamp consists of two dates: Creation and modification date (the +latter being recorded when the file is closed). CP/M Plus further +allows optionally to record the access instead of creation date as first +time stamp.
+ +
+2 bytes (little-endian) days starting with 1 at 01-01-1978 +
+ +1 byte hour in BCD format +
+ +1 byte minute in BCD format +

+
+ + +  +Disc labels - CP/M Plus supports disc labels, which are stored in an arbitrary directory +entry. +

+The structure of disc labels is:
+ +
+1 byte status 0x20 +
+ +F0-E2 are the disc label +
+ +1 byte mode: bit 7 activates password protection, bit 6 causes time stamps on +access, but 5 causes time stamps on modifications, bit 4 causes time stamps on +creation and bit 0 is set when a label exists. Bit 4 and 6 are exclusively set. +
+ +1 byte password decode byte: To decode the password, xor this byte with the password +bytes in reverse order. To encode a password, add its characters to get the +decode byte. +
+ +2 reserved bytes +
+ +8 password bytes +
+ +4 bytes label creation time stamp +
+ +4 bytes label modification time stamp +

+
+ + +  +Passwords - CP/M Plus supports passwords, which are stored in an arbitrary directory entry. +

+ +The structure of these entries is:
+ +
+ +1 byte status (user number plus 16) +
+ +F0-E2 are the file name and its extension. +
+ +1 byte password mode: bit 7 means password required for reading, bit 6 for writing +and bit 5 for deleting. +
+ +1 byte password decode byte: To decode the password, xor this byte with the password +bytes in reverse order. To encode a password, add its characters to get the +decode byte. +
+ +2 reserved bytes +
+ +8 password bytes +

+Updated: June 16, 2008

+ + +  +NAME cpmchattr - change file attributes on CP/M files.

+ + +  +SYNOPSIS

+ + +cpmchattr + +[-f + +format] + +image + +attrib + +file-pattern + +... + +

+ +Note: Wildcards like *.com should be preceded with the user number +using a pattern like 0:*.com. +
+
+ + +  +DESCRIPTION

+ +Cpmchattr changes the file attributes for files on CP/M disks. +
+
+ + +  +OPTIONS

+ +
+ +
-f
+ +Use the given CP/M disk format instead of the default format. +

+For Apple II CP/M 80 users the cpmchattr command may have no practical +effect. Try +cpmchmod instead for setting read only +attributes. +

+ +
attrib Set the file attributes as given.
+ +
+
+ +  +FILE ATTRIBUTES - The file attribute string can contain the characters +1,2,3,4,s,a,N and M.

+ +The meanings of these are: + +
+
1-4
+ +
+The CP/M "user attributes" F1-F4. CP/M does not assign any +meaning to these attributes, though MP/M does. +
+ +
s
+ +
+The file is a system file. This attribute can also be set by +cpmchmod(1). + +
a
+ +
+The file has been backed up. +
N
+ +
+Reset all attributes to zero. So the string "N1r" resets all attributes and +then sets F1 and Read-Only. +
M
+ +
+Attributes after an M are unset rather than set. The string "12M34" sets +atttributes F1 and F2, and unsets F3 and F4. +

+
+ +  +RETURN VALUE - Upon successful completion, exit code 0 is returned.

+ +This will likely only be of interest to programmers. In a Win32 system the +exit code can be trapped in a batch file as an "ERRORLEVEL" or as a +return value when run from another Win32 console program written in a +language like C. +

+ +  +ERRORS - Any errors are indicated by exit code 1.

+ +This will likely only be of interest to programmers. In a Win32 system the +exit code can be trapped in a batch file as an "ERRORLEVEL" or as a +return value when run from another Win32 console program written in a +language like C. +

+ +  +FILES - diskdefs - CP/M disk format definitions

+ +The diskdefs file is a plain ascii text file that serves as a database of +disk and disk image format definitions. It can be reviewed for available CP/M +formats and their names. For Apple II CP/M 80 users the disk +image formats apple-do and apple-po are available. +

+For Apple II CP/M 80 users the cpmchattr command may have no +practical effect. Try +cpmchmod instead for setting read only +attributes. +

+The possible locations where cpmtools first looks for the diskdefs file: +
+
+- Can vary depending on the preferences of the person who builds the +cpmtools binaries (executables) from the source code. +

+- The location is also installation dependent and the diskdefs file +may also have been renamed. +
+
+If it's not found the current (work) directory is then searched for a +file called diskdefs. +
+
+On a unix-like system, a ${prefix}/share/ style path +like /usr/local/share/ is a possible place that cpmtools will first +look for diskdefs. +
+
+In a Win32 system sometimes unix-like shells like cygwin +are used to run cpmtools instead of Windows cmd. For those installations +unix-like conventions probably apply. +
+
+For cpmtools installations targetted at the average +Windows user who does not have a unix-like shell and uses the Windows cmd +prompt to run cpmtools there is no standard shared place that cpmtools will first +look for diskdefs. Pathed File names like \cpm\diskdefs or +even c:\cpmtools\diskdefs are possible. +

+ +  +DESCRIPTION

+ +Cpmcp copies one or more files to or from a CP/M disk. +
+
+ + +When copying multiple files, the last argument must be a drive or directory. +The drive letter does not matter because the device is specified by the +image, it is only used to specify which direction you want to copy. The user +number is specified after the drive letter, if omitted user 0 is used. +

+ +You can use * and ? as "wildcards" in CP/M file names, +which have the same meaning in unix-like shells, and also on the MS-DOS +and Windows command lines for file name patterns. + +
+
+ +  +OPTIONS

+ +
+ +
-f
+ +Use the given CP/M disk format instead of the default format. +

+For Apple II CP/M 80 +users the disk image formats apple-do and apple-po are available. These +are DOS3.3 order and ProDOS order disk image formats respectively, and must always be specified +using the form -f apple-do or -f apple-po. +

+ +
-p
+Preserve time stamps when copying files from CP/M to UNIX (not +implemented for copying the other way so far). +
+
+ + +
-t
+Convert text files between CP/M and UNIX conventions. +
+ +
+ +Examples: +
+
+The following example shows how to copy a file from an Apple II DOS 3.3 order cpm disk image +to the current directory: +
+
+cpmcp -f apple-do exmplcpm.dsk bhead.c 0:bhead.c +

+ + +  +NAME cpmls - list sorted contents of directory

+ +  +SYNOPSIS

+ + +cpmls + +[-d|-D|-F|-A|-l[-c][-i]] + +[-f + +format] + +image + +[file-pattern...] +

+ +  +DESCRIPTION

+ +Cpmls lists the sorted contents of the directory. +
+
+ +  +OPTIONS

+ +
+ +
-f
+ +Use the given CP/M disk format instead of the default format. +

+For Apple II CP/M 80 +users the disk image formats apple-do and apple-po are available. These +are DOS3.3 order and ProDOS order disk image formats respectively, and must always be specified +using the form -f apple-do or -f apple-po. +

+ +
-d
+Old CP/M 2.2 dir output. +

+ +
-D
+P2DOS 2.3 ddir-like output. +

+ +
-F
+CP/M 3.x dir output. +

+ +
-A
+E2fs lsattr-like output. +

+ +
-l
+Long UNIX-style directory listing including size, time stamp and user number. +

+ +
-c
+Output the creation time, not the modification time. +

+ +
-i
+Print index number of each file. +
+
+ +Example: +
+
+The following example shows how to list the files on an Apple II DOS 3.3 +order cpm disk image using a unix-like output: +
+
+cpmls -f apple-do -l exmplcpm.dsk +
+
+ +  +RETURN VALUE - Upon successful completion, exit code 0 is returned.

+ +This will likely only be of interest to programmers. In a Win32 system +the exit code can be trapped in a batch file as an "ERRORLEVEL" or as a +return value when run from another Win32 console program written in a +language like C. +

+ +  +ERRORS - Any errors are indicated by exit code 1.

+ +This will likely only be of interest to programmers. In a Win32 system the +exit code can be trapped in a batch file as an "ERRORLEVEL" or as a +return value when run from another Win32 console program written in a +language like C. +

+ +  +FILES - diskdefs - CP/M disk format definitions

+ +The diskdefs file is a plain ascii text file that serves as a database of +disk and disk image format definitions. It can be reviewed for available +CP/M formats and their names. For Apple II CP/M 80 users the disk +image formats apple-do and apple-po are available. +

+The possible locations where cpmtools first looks for the diskdefs file: +
+
+- Can vary depending on the preferences of the person who builds the +cpmtools binaries (executables) from the source code. +

+- The location is also installation dependent and the diskdefs file +may also have been renamed. +
+
+If it's not found the current (work) directory is then searched for a +file called diskdefs. +
+
+On a unix-like system, a ${prefix}/share/ style path +like /usr/local/share/ is a possible place that cpmtools will first +look for diskdefs. +
+
+In a Win32 system sometimes unix-like shells like cygwin +are used to run cpmtools instead of Windows cmd. For those installations +unix-like conventions probably apply. +
+
+For cpmtools installations targetted at the average +Windows user who does not have a unix-like shell and uses the Windows cmd +prompt to run cpmtools there is no standard shared place that cpmtools will first +look for diskdefs. Pathed File names like \cpm\diskdefs or +even c:\cpmtools\diskdefs are possible. +

+ +  +SYNOPSIS

+ +fsck.cpm + +[-f + +format] + +[-n] + +image + +

+ + +  +DESCRIPTION

+ +Fsck.cpm is used to check and repair a CP/M file system. +
+
+After reading the directory, it makes two passes. The first pass checks +extent fields for range and format violations (bad status, extent number, +last record byte count, file name, extension, block number, record count, +size of .COM files, time stamp format, invalid password characters, invalid +time stamp mode). The second pass checks extent connectivity (multiple +allocated blocks and duplicate directory entries). +
+
+fsck.cpm can not yet repair all errors. +
+
+ +  +OPTIONS

+ +
+ +
-f
+ +Use the given CP/M disk format instead of the default format. +

+For Apple II CP/M 80 +users the disk image formats apple-do and apple-po are available. These +are DOS3.3 order and ProDOS order disk image formats respectively, and must always be specified +using the form -f apple-do or -f apple-po. +

+ + +

+
+ + +  +DIAGNOSTICS - image: used/total files (n.n% non-contiguos), used/total blocks +
+
+No inconsistencies could be found. The number of used files actually +is the number of used extents. Since a file may use more than +one extent, this may be greater than the actual number of files, but a +correct measure would not reflect how many files could still be created +at most. A file is considered fragmented, if sequential data blocks +pointed to by the same extent do not have sequential block numbers. +The number of used blocks includes the blocks used for system tracks +and the directory. +

 +Cpmtools 2.9 Executables for Windows Users
 +
+ + +
+Introduction +
+
+ +Cpmtools is a suite of command line utilities which allow access to +CP/M file systems. It is available on many platforms. This document +is targetted at the use of the cpmtools Win32 executables at +the Windows command prompt by Windows users who know how to use +command line utilities and disk images +and who may not wish to create cpmtools executables from +source code... just to use them. + +

+
+The source for the latest version of cpmtools is available as +a GNU zipped tape archive from: +
+
+ +http://www.moria.de/~michael/cpmtools/ + +
+
+The cpmtools source used in cygwin to build both the Windows binary (Executable) versions of +cpmtools 2.9 noted below is available from the +www.cpm8680.com Website in a zip file format: +
+
+ +http://www.cpm8680.com/cpmtools/cpmtools-2.9.zip + +
+
+For Windows Users who do not wish to make working programs from source code, a compiled +Native Win32 Binary (Executable) version of cpmtools 2.9 is available from the +www.cpm8680.com Website in a zip file format: +
+
+ +http://www.cpm8680.com/cpmtools/cpmtools-2.9-Win32.zip + +
+
+Just unzip with pathnames intact to the root of your local drive (usually C:) +and open-up a cmd prompt in the \cpmtools directory (Windows XP and Vista users +can click-on the cpmtools XP Shortcut) +and you should be good to go. The document you are reading and the program description documents +that it links to are included in the Windows zip file. To use them just click-on them from Windows explorer and +in the \cpmtools\docs directory and +they will load into your favorite web browser. +
+
+ +The distribution noted above has the following customizations: +
+
+The default disk image format is apple-do. This means that if you are working +with Apple II DOS 3.3 order disk images you never need to include the -f apple-do +format option when typing in your command line. +
+
+The diskdefs file is called \cpmtools\diskdefs. This has been hardcoded +into the executables. This means that you can add the \cpmtools directory +to your PATH and the disk and disk image format definitions file will be found. +Users of earlier versions of Windows than XP that support Win32 will need to open a command +prompt and run \cpmtools\cpmtools.bat to set their PATH. +
+
+A Windows XP Shortcut has been added for Windows XP Users. This should +also work in Windows Vista. This means that Windows XP and Vista users can just +click on this shortcut in Windows Explorer or the Shortcut can be copied to +the desktop. + +

+
+For cygwin Users who do not wish to make working programs from source code, a compiled +cygwin 5 Binary (Executable) version of cpmtools 2.9 is available from the +www.cpm8680.com Website in a zip file format: +
+
+ +http://www.cpm8680.com/cpmtools/cpmtools-2.9-cygwin.zip + +
+
+Outside cygwin just unzip with pathnames intact to the root of the drive that the cygwin +version 5 directory is installed on (\cygwin is assumed). If you are doing this inside cygwin +using zip and cygwin is installed on C:, then cd \cygdrive\c before un-zipping. +
+
+The cygwin installation comes complete with the manpages but not the html manual. +It overlays your cygwin installation so review the zip before installing. +
+
+ +The distribution noted above has the following customization: +
+
+The default disk image format is apple-do. This means that if you are working +with Apple II DOS 3.3 order disk images you never need to include the -f apple-do +format option when typing in your command line. +
+
+Other than that, it is what you would get if you built from scratch then installed +using "make install". If you wish to know more you should download +the source as well. + +

+ +  +SYNOPSIS

+ +mkfs.cpm + +[-f + +format] + +[-b + +boot] + +[-L + +label] + +image + +
+
+ +  +DESCRIPTION

+ +Mkfs.cpm makes a CP/M file system on an image file or device. +
+
+ +  +OPTIONS

+ +
+ +
-f
+ +Use the given CP/M disk format instead of the default format. +

+For Apple II CP/M 80 +users the disk image formats apple-do and apple-po are available. These +are DOS3.3 order and ProDOS order disk image formats respectively, and must always be specified +using the form -f apple-do or -f apple-po. +

+ +
-b bootblock
+ +
+Write the contents of the file bootblock to the system tracks +instead of filling them with 0xe5. This option can be used up to four +times. The file contents (typically boot block, CCP, BDOS and BIOS) +are written to sequential sectors, padding with 0xe5 if needed. +
+
+ +
-L label
+
+Label the file system. This is only supported by CP/M Plus. +

+
+ +  +RETURN VALUE - Upon successful completion, exit code 0 is returned.

+ +This will likely only be of interest to programmers. In a Win32 system +the exit code can be trapped in a batch file as an "ERRORLEVEL" or as a +return value when run from another Win32 console program written in a +language like C. +

+ +  +ERRORS - Any errors are indicated by exit code 1.

+ +This will likely only be of interest to programmers. In a Win32 system +the exit code can be trapped in a batch file as an "ERRORLEVEL" or as a +return value when run from another Win32 console program written in a +language like C. +

+ +  +FILES - diskdefs - CP/M disk format definitions

+ +The diskdefs file is a plain ascii text file that serves as a database of +disk and disk image format definitions. It can be reviewed for available +CP/M formats and their names. For Apple II CP/M 80 users the disk +image formats apple-do and apple-po are available. +

+The possible locations where cpmtools first looks for the diskdefs file: +
+
+- Can vary depending on the preferences of the person who builds the +cpmtools binaries (executables) from the source code. +

+- The location is also installation dependent and the diskdefs file +may also have been renamed. +
+
+If it's not found the current (work) directory is then searched for a +file called diskdefs. +
+
+On a unix-like system, a ${prefix}/share/ style path +like /usr/local/share/ is a possible place that cpmtools will first +look for diskdefs. +
+
+In a Win32 system sometimes unix-like shells like cygwin +are used to run cpmtools instead of Windows cmd. For those installations +unix-like conventions probably apply. +
+
+For cpmtools installations targetted at the average +Windows user who does not have a unix-like shell and uses the Windows cmd +prompt to run cpmtools there is no standard shared place that cpmtools will first +look for diskdefs. Pathed File names like \cpm\diskdefs or +even c:\cpmtools\diskdefs are possible. +

By contrast, the GNU General Public +License is intended to guarantee your freedom to share and change free +software--to make sure the software is free for all its users. This +General Public License applies to most of the Free Software +Foundation's software and to any other program whose authors commit to +using it. (Some other Free Software Foundation software is covered by +the GNU Library General Public License instead.) You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if you +distribute copies of the software, or if you modify it. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must give the recipients all the rights that +you have. You must make sure that they, too, receive or can get the +source code. And you must show them these terms so they know their +rights. + + We protect your rights with two steps: (1) copyright the software, and +(2) offer you this license which gives you legal permission to copy, +distribute and/or modify the software. + + Also, for each author's protection and ours, we want to make certain +that everyone understands that there is no warranty for this free +software. If the software is modified by someone else and passed on, we +want its recipients to know that what they have is not the original, so +that any problems introduced by others will not reflect on the original +authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that redistributors of a free +program will individually obtain patent licenses, in effect making the +program proprietary. To prevent this, we have made it clear that any +patent must be licensed for everyone's free use or not licensed at all. + + The precise terms and conditions for copying, distribution and +modification follow. + + GNU GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License applies to any program or other work which contains +a notice placed by the copyright holder saying it may be distributed +under the terms of this General Public License. The "Program", below, +refers to any such program or work, and a "work based on the Program" +means either the Program or any derivative work under copyright law: +that is to say, a work containing the Program or a portion of it, +either verbatim or with modifications and/or translated into another +language. (Hereinafter, translation is included without limitation in +the term "modification".) Each licensee is addressed as "you". + +Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running the Program is not restricted, and the output from the Program +is covered only if its contents constitute a work based on the +Program (independent of having been made by running the Program). +Whether that is true depends on what the Program does. + + 1. You may copy and distribute verbatim copies of the Program's +source code as you receive it, in any medium, provided that you +conspicuously and appropriately publish on each copy an appropriate +copyright notice and disclaimer of warranty; keep intact all the +notices that refer to this License and to the absence of any warranty; +and give any other recipients of the Program a copy of this License +along with the Program. + +You may charge a fee for the physical act of transferring a copy, and +you may at your option offer warranty protection in exchange for a fee. + + 2. You may modify your copy or copies of the Program or any portion +of it, thus forming a work based on the Program, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) You must cause the modified files to carry prominent notices + stating that you changed the files and the date of any change. + + b) You must cause any work that you distribute or publish, that in + whole or in part contains or is derived from the Program or any + part thereof, to be licensed as a whole at no charge to all third + parties under the terms of this License. + + c) If the modified program normally reads commands interactively + when run, you must cause it, when started running for such + interactive use in the most ordinary way, to print or display an + announcement including an appropriate copyright notice and a + notice that there is no warranty (or else, saying that you provide + a warranty) and that users may redistribute the program under + these conditions, and telling the user how to view a copy of this + License. (Exception: if the Program itself is interactive but + does not normally print such an announcement, your work based on + the Program is not required to print an announcement.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Program, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Program, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Program. + +In addition, mere aggregation of another work not based on the Program +with the Program (or with a work based on the Program) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may copy and distribute the Program (or a work based on it, +under Section 2) in object code or executable form under the terms of +Sections 1 and 2 above provided that you also do one of the following: + + a) Accompany it with the complete corresponding machine-readable + source code, which must be distributed under the terms of Sections + 1 and 2 above on a medium customarily used for software interchange; or, + + b) Accompany it with a written offer, valid for at least three + years, to give any third party, for a charge no more than your + cost of physically performing source distribution, a complete + machine-readable copy of the corresponding source code, to be + distributed under the terms of Sections 1 and 2 above on a medium + customarily used for software interchange; or, + + c) Accompany it with the information you received as to the offer + to distribute corresponding source code. (This alternative is + allowed only for noncommercial distribution and only if you + received the program in object code or executable form with such + an offer, in accord with Subsection b above.) + +The source code for a work means the preferred form of the work for +making modifications to it. For an executable work, complete source +code means all the source code for all modules it contains, plus any +associated interface definition files, plus the scripts used to +control compilation and installation of the executable. However, as a +special exception, the source code distributed need not include +anything that is normally distributed (in either source or binary +form) with the major components (compiler, kernel, and so on) of the +operating system on which the executable runs, unless that component +itself accompanies the executable. + +If distribution of executable or object code is made by offering +access to copy from a designated place, then offering equivalent +access to copy the source code from the same place counts as +distribution of the source code, even though third parties are not +compelled to copy the source along with the object code. + + 4. You may not copy, modify, sublicense, or distribute the Program +except as expressly provided under this License. Any attempt +otherwise to copy, modify, sublicense or distribute the Program is +void, and will automatically terminate your rights under this License. +However, parties who have received copies, or rights, from you under +this License will not have their licenses terminated so long as such +parties remain in full compliance. + + 5. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Program or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Program (or any work based on the +Program), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Program or works based on it. + + 6. Each time you redistribute the Program (or any work based on the +Program), the recipient automatically receives a license from the +original licensor to copy, distribute or modify the Program subject to +these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 7. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Program at all. For example, if a patent +license would not permit royalty-free redistribution of the Program by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Program. + +If any portion of this section is held invalid or unenforceable under +any particular circumstance, the balance of the section is intended to +apply and the section as a whole is intended to apply in other +circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system, which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 8. If the distribution and/or use of the Program is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Program under this License +may add an explicit geographical distribution limitation excluding +those countries, so that distribution is permitted only in or among +countries not thus excluded. In such case, this License incorporates +the limitation as if written in the body of this License. + + 9. The Free Software Foundation may publish revised and/or new versions +of the General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + +Each version is given a distinguishing version number. If the Program +specifies a version number of this License which applies to it and "any +later version", you have the option of following the terms and conditions +either of that version or of any later version published by the Free +Software Foundation. If the Program does not specify a version number of +this License, you may choose any version ever published by the Free Software +Foundation. + + 10. If you wish to incorporate parts of the Program into other free +programs whose distribution conditions are different, write to the author +to ask for permission. For software which is copyrighted by the Free +Software Foundation, write to the Free Software Foundation; we sometimes +make exceptions for this. Our decision will be guided by the two goals +of preserving the free status of all derivatives of our free software and +of promoting the sharing and reuse of software generally. + + NO WARRANTY + + 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY +FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN +OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES +PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED +OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF +MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS +TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE +PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, +REPAIR OR CORRECTION. + + 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR +REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, +INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING +OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED +TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY +YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER +PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE +POSSIBILITY OF SUCH DAMAGES. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software; you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation; either version 2 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program; if not, write to the Free Software + Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307 USA + + +Also add information on how to contact you by electronic and paper mail. + +If the program is interactive, make it output a short notice like this +when it starts in an interactive mode: + + Gnomovision version 69, Copyright (C) year name of author + Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, the commands you use may +be called something other than `show w' and `show c'; they could even be +mouse-clicks or menu items--whatever suits your program. + +You should also get your employer (if you work as a programmer) or your +school, if any, to sign a "copyright disclaimer" for the program, if +necessary.

+TABLE OF CONTENTS

+ + + +
+

+INTRODUCTION

+The Telemark Assembler (TASM) is a table driven cross assembler for the +MS-DOS and LINUX environments. Assembly source code, written in the appropriate +dialect (generally very close to the manufacturers assembly language), +can be assembled with TASM, and the resulting object code transferred to +the target microprocessor system via PROM or other mechanisms. + +

The microprocessor families supported by TASM are: +

    +
  • +6502
    • + +
  • +6800/6801/68HC11
    • + +
  • +6805
    • + +
  • +8048
    • + +
  • +8051
    • + +
  • +8080/8085, Z80
    • + +
  • +TMS32010, TMS320C25
    • + +
  • +TMS7000
    • + +
  • +8096/80196
    • +
+The user so inclined may build tables for other microprocessors. The descriptions +of the various existing tables and instructions on building new tables +are not in this document but can be found in the TASMTABS.HTM file on the +TASM distribution disk. + +

TASM characteristics include: +

    +
  1. +Powerful expression parsing (17 operators).
    2. + +
  2. +Supports a subset of the 'C' preprocessor commands.
    3. + +
  3. +Macro capability (through use of DEFINE directive).
    4. + +
  4. +Multiple statements per line.
    5. + +
  5. +Four object file formats: Intel hex, MOS Technology hex, Motorola hex, +binary.
    6. + +
  6. +Absolute code generation only.
    7. + +
  7. +Source code available (in C).
    8. + +
  8. +Uniform syntax across versions for different target machines.
    9. + +
  9. +Features in support of PROM programming (preset memory, contiguous block).
    10. + +
  10. +Supports extended instructions for many of the supported microprocessor +families.
    11. + +
  11. +Tables read at run time - single TASM executable for all table versions.
    12. + +
  12. +Symbol table export for inclusion in subsequent assemblies.
    13. + +
  13. +Symbol table export file for import with some simulator products.
    14. +
+ +
+

+SHAREWARE

+TASM is distributed as shareware. TASM is not in the public domain. The +TASM distribution files may be freely copied (excluding the source code +files) and freely used for the purpose of evaluating the suitability of +TASM for a given purpose. Use of TASM beyond a reasonable evaluation period +requires registration. Prolonged use without registration is unethical.  +
+

+INVOCATION

+TASM can be invoked as follows (optional fields shown in brackets, symbolic +fields in italics): +
  tasm -pn [-options ...] src_file [obj_file [lst_file [exp_file [sym_file]]]]
+Where options can be one or more of the following: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
-table Specify version (table = table designation) 
-ttable Table (alternate form of above) 
-aamask Assembly control (optional error checking) 
-b Produce object in binary (.COM) format 
-c Object file written as a contiguous block 
-dmacro Define a macro (or just a macro label) 
-e Show source lines after macro expansion 
-ffillbyte Fill entire memory space with fillbyte (hex) 
-gobjtype Object file (0=Intel Hex, 1=MOS Tech, 2=Motorola, +3=binary,4=Intel Hex (Word)) 
-h Produce hex table of the assembled code (in list +file) 
-i Ignore case for labels 
-l[al] Produce a label table in the listing 
-m Produce object in MOS Technology format 
-oobytes Bytes per object record (for hex obj formats) 
-p[lines] Page the listing file (lines per page. default=60) 
-q Quiet, disable the listing file 
-s Write a symbol table file 
-x[xmask] Enable extended instruction set (if any) 
-y Time the assembly 
+

The filename parameters are defined as follows: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
src_file Source file name 
obj_file Object code file name 
lst_file Listing file name 
exp_file Symbol export file (only if the EXPORT directive +is used).
sym_file Symbol table file (only if the -s option +or the SYM/AVSYM directives are used). 
+

The source file must be specified. If not, some usage information is displayed. +Default file names for all the other files are generated if they are not +explicitly provided. The filename is formed by taking the source filename +and changing the extension to one of the following: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Extension File type 
.OBJ Object file 
.LST Listing file 
.EXP Symbol export file 
.SYM Symbol table file 
+

TASM has no built-in instruction set tables. Instruction set definition +files are read at run time. TASM determines which table to use based on +the '-table' field shown above. For example, to assemble the code +in a file called source.asm, one would enter +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
tasm -48 source.asm for an 8048 assembly 
tasm -65 source.asm for a 6502 assembly 
tasm -51 source.asm for an 8051 assembly. 
tasm -85 source.asm for an 8085 assembly. 
tasm -80 source.asm for a Z80 assembly. 
tasm -05 source.asm for a 6805 assembly. 
tasm -68 source.asm for a 6800/6801/68HC11 assembly. 
tasm -70 source.asm for a TMS7000 assembly. 
tasm -3210 source.asm for a TMS32010 assembly. 
tasm -3225 source.asm for a TMS320C25 assembly. 
tasm -96 source.asm for a 8096/80196 assembly
+

+Tables are read from a file named by taking the digits specified after +the '-' and appending it to 'TASM' then appending the '.TAB' extension. +Thus, the -48 flag would cause the tables to be read from the file +'TASM48.TAB'. + +

It is possible to designate tables by non numeric part numbers if the +-t flag is used. For example, if a user built a table called TASMF8.TAB +then TASM could be invoked as follows: +

    tasm -tf8 source.asm
+Each option flag must be preceded by a dash. Options need not precede the +file names. The various options are described in the sections that follow. +

+a - Assembly Control

+TASM can provide additional error checking by specifying the -a +option at the time of execution. If the -a is provided without a +digit following, then all the available error checking is done. If a digit +follows, then it is used as a mask to determine the error checks to be +made. The bits of the mask are defined as follows: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Bit Option Default Description 
0 -a1 OFF Check for apparent illegal use of indirection 
1 -a2 ON Check for unused data in the arguments 
2 -a4 ON Check for duplicate labels 
3 -a8 OFF Check for non-unary operators at start of expression. 
+

Combinations of the above bits can also be used. For example, -a5 +would enable the checking for illegal indirection and duplicate labels. + +

Illegal indirection applies to micros that use parenthesis around an +argument to indicate indirection. Since it is always legal to put an extra +pair of parenthesis around any expression (as far as the expression parser +is concerned), the user may think that he/she is indicating indirection +for an instruction that has no indirection and TASM would not complain. +Enabling this checking will result in an error message (warning) whenever +an outer pair of parenthesis is used and the instruction set definition +table does not explicitly indicate that to be a valid form of addressing. + +

Unused data in arguments applies to cases where a single byte of data +is needed from an argument, but the argument contains more than one byte +of data. If a full sixteen bit address is used in a 'Load Immediate' type +instruction that needs only a single byte, for example, an error message +would be generated. Here is an example (6502 code): +

    0001   1234                    .org $1234
+    test.asm line 0002: Unused data in MS byte of argument.
+    0002   1234 A9 34       start  lda  #start
+To make the above checks occur whenever you do an assembly, add a line +like this to your AUTOEXEC.BAT file: +
    SET TASMOPTS=-a
+ +

+b - Binary Object Format

+This option causes the object file to be written in binary - one byte for +each byte of code/data. Note that no address information is included in +the object file in this format. The contiguous block (-c) output mode is +forced when this option is invoked. This flag is equivalent to -g3. +

+c - Contiguous Block Output

+If this option is specified, then all bytes in the range from the lowest +used byte to the highest will be defined in the object file. Normally, +with the default Intel Hex object format enabled, if the Program Counter +(PC) jumps forward because of an .ORG directive, the +bytes skipped over will not have any value assigned them in the object +file. With this option enabled, no output to the object file occurs until +the end of the assembly at which time the whole block is written. This +is useful when using TASM to generate code that will be put into a PROM +so that all locations will have a known value. This option is often used +in conjunction with the -f option to ensure all unused bytes will have +a known value. +

+d - Define a Macro

+Macros are defined on the command line generally to control the assembly +of various IFDEF's that are in the source file. This is a convenient way +to generate various versions of object code from a single source file. +

+e - Expand Source.

+Normally TASM shows lines in the listing file just as they are in the source +file. If macros are in use (via the DEFINE directive) +it is sometimes desirable to see the source lines after expansion. Use +the '-e' flag to accomplish this. +

+f - Fill Memory.

+This option causes the memory image that TASM maintains to be initialized +to the value specified by the two hex characters immediately following +the 'f'. TASM maintains a memory image that is a full 64K bytes in size +(even if the target processor cannot utilize that memory space). Invocation +of this option introduces a delay at start up time. +

+g - Object File Format.

+TASM can generate object code in the formats indicated below: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Option Description
-g0 Intel hex (default) 
-g1 MOS Technology hex (same as -m) 
-g2 Motorola hex 
-g3 binary (same as -b) 
-g4 Intel hex with word addresses
+

The -m and -b flags may also be used, as indicated above. +If both are used the right-most option on the command line will be obeyed. + +

See the section on OBJECT FILE FORMATS for descriptions of each +of the above. +

+h - Hex Object Code Table.

+This option causes a hex table of the produced object code to appear in +the listing file. Each line of the table shows sixteen bytes of code. +

+i - Ignore Case in Labels.

+TASM is normally case sensitive when dealing with labels. For those that +prefer case insensitivity, the '-i' command line option can be employed. +

+l - Label Table.

+This option causes a label table to appear in the listing file. Each label +is shown with its corresponding value. Macro labels (as established via +the DEFINE directives) do not appear. + +

Two optional suffixes may follow the -l option: +
  + + + + + + + + + + + + + + + + + + +
Suffix Description 
l Use long form listing 
a Show all labels (including local labels) 
+

The suffix should immediately follow the '-l'. Here are some examples: +
  + + + + + + + + + + + + + + + + + + + + + + + + +
-l to show non-local labels in the short form 
-la to show all labels in the short form 
-ll to show non-local labels in the long form 
-lal to show all labels in the long form 
+ +

+m - MOS Technology Object Format.

+This option causes the object file to be written in MOS Technology hex +format rather than the default Intel hex format. See section on OBJECT +FILE FORMATS for a description of the format. +

+o - Set Number of Bytes per Object Record.

+When generating object code in either the MOS Technology format or the +Intel hex format, a default of 24 (decimal) bytes of object are defined +on each record. This can be altered by invoking the '-o' option immediately +followed by two hex digits defining the number of bytes per record desired. +For example, if 32 bytes per record are desired, one might invoke TASM +as: +
    tasm -48 -o20 source.asm
+ +

+p - Page Listing File.

+This option causes the listing file to have top of page headers and form +feeds inserted at appropriate intervals (every sixty lines of output). +To override the default of sixty lines per page, indicate the desired number +of lines per page as a decimal number immediately following the '-p'. Here +is an example: +
    tasm -48 -p56 source.asm
+ +

+q - Disable Listing File.

+This option causes all output to the listing file to be suppressed, unless +a .LIST directive is encountered in the source file (see LIST/NOLIST +directives). +

+s - Enable Symbol File Generation.

+If this flag is set, a symbol file is generated at the end of the assembly. +The format of the file is one line per label, each label starts in the +first column and is followed by white space and then four hexadecimal digits +representing the value of the label. The following illustrates the format: +
    label1         FFFE
+    label2         FFFF
+    label3         1000
+The symbol file name can be provided as the fifth file name on the command +line, or the name will be generated from the source file name with a '.SYM' +extension. The symbol table file can also be generated by invoking the +SYM directive. The AVSYM directive also generates the symbol file but in +a different format (see section on ASSEMBLER +DIRECTIVES). +

+t - Table Name.

+As an alternative to specifying the instruction set table as two decimal +digits, the table indication may be proceeded by the '-t' option. This +is useful if the desired table name starts with a non-numeric. Thus, a +table for an F8 might be selected as: +
    tasm -tf8 source.asm
+TASM would expect to read the instruction set definition tables from a +file named TASMF8.TAB. +

+x - Enable Extended Instruction Set.

+If a processor family has instructions that are valid for only certain +members, this option can be used to enable those beyond the basic standard +instruction set. A hex digit may follow the 'x' to indicate a mask value +used in selecting the appropriate instruction set. Bit 0 of the mask selects +the basic instruction set, thus a '-x1' would have no effect. A '-x3' would +enable the basic set plus whatever instructions have bit 1 set in their +class mask. A '-x' without a digit following is equivalent to a '-xf' which +sets all four of the mask bits. The following table indicates the current +extended instruction sets available in the TASM tables: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

+  +
  + +

The above table does not attempt to show the many microprocessor family +members that may apply under a given column. + +

See the TASMTABS.HTM on-line document for details on each specific table. +

+y - Enable Assembly Timing

+If this option is enabled TASM will generate a statement of elapsed time +and assembled lines per second at the end of the assembly. +

+ +
ENVIRONMENT VARIABLES

+The TASM environment can be customized by using the environment variables +listed below: +

+TASMTABS

+The TASMTABS variable specifies the path to be searched for TASM instruction +set definition tables. If it is not defined then the table(s) must exist +in the current working directory. The following examples illustrate possible +usage: +
  + + + + + + + + + + + + +
For MSDOS set TASMTABS=C:\TASM
For LINUX TASMTABS=/tasm
+ +

+TASMOPTS

+This variable specifies TASM command line options that are to be invoked +every time TASM is executed. For example, if TASM is being used for 8048 +assemblies with binary object file output desired, the following statement +would be appropriate in the AUTOEXEC.BAT file: +
    set TASMOPTS=-48 -b
+ +

+TASMERRFORMAT

+The TASMERRFORMAT variable provides user control of the format of error +messages.  The format string must be a valid printf format string +for ANSI C.  The default value is: +
    +
    "%s line %04d: %s %s"
    +
+Which provides error messages like this: +
    +
    Main.asm line 1234: No such label: Start
    +
+The four fields associated with an error message are: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Field DescriptionAssociated Data Type (ANSI C)
File namechar *
Line number within fileint
Error descriptionchar *
Error data (optional)char *
+ + +

No user control of the order of the error message fields is provided. +
Here are sample usages: + +

For MSDOS: +

    +
    set TASMERRFORMAT=”%s(%d) %s %s”
    +
+For LINUX: +
    +
    TASMERRFORMAT=”%s(%d) %s %s”
    +

+

+EXIT CODES

+When TASM terminates, it will return to the OS the following exit codes: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Exit Code Definition
0 Normal completion, no assembly errors 
1 Normal completion, with assembly errors 
2 Abnormal completion, insufficient memory 
3 Abnormal completion, file access error 
4 Abnormal completion, general error 
+

Exit codes 2 and above will also be accompanied by messages to the console +concerning the error. +
+

+

+SOURCE FILE FORMAT

+Statements in the source file must conform to a format as follows (except +for assembler directive statements which are described in a subsequent +section): +
  +
    label operation operand comment
+All of the fields are optional, under appropriate circumstances. An arbitrary +amount of white space (space and tabs) can separate each field (as long +as the maximum line length of 255 characters is not exceeded). Each of +the fields are described in the following sections. +

+Label Field.

+If the first character of the line is alphabetic, it is assumed to be the +start of a label. Subsequent characters are accepted as part of that label +until a space, tab, or ':' is encountered. The assembler assigns a value +to the label corresponding to the current location counter. Labels can +be a maximum of 32 characters long. Labels can contain upper and lower +case letters, digits, underscores, and periods (the first character must +be alphabetic). Labels are case sensitive - the label 'START' is a different +label from 'start' - unless the '-i' (ignore case) option is enabled. +

+Operation Field.

+The operation field contains an instruction mnemonic which specifies the +action to be carried out by the target processor when this instruction +is executed. The interpretation of each mnemonic is dependent on the target +microprocessor (as indicated by the selected TASM table). The operation +field may begin in any column except the first. The operation field is +case insensitive. +

+Operand Field.

+The operand field specifies the data to be operated on by the instruction. +It may include expressions and/or special symbols describing the addressing +mode to be used. The actual format and interpretation is dependent on the +target processor. For a description of the format for currently supported +processors, see the TASMTABS.DOC file on the TASM distribution disk. +

+Comment Field.

+The comment field always begins with a semicolon. The rest of the line +from the semicolon to the end of the line is ignored by TASM, but passed +on to the listing file for annotation purposes. The comment field must +be the last field on a line, but it may be the only field, starting in +column one, if desired. +

+Multiple Statement Lines.

+If the backslash character is encountered on a source line, it is treated +as a newline. The remainder of the line following the backslash will be +processed as an independent line of source code. This allows one to put +multiple statements on a line. This facility is not so useful of itself, +but when coupled with the capability of the DEFINE directive, powerful +multiple statement macros can be constructed (see section on ASSEMBLER +DIRECTIVES). Note that when using the statement separator, the +character immediately following it should be considered the first character +of a new line, and thus must either be a start of a label or white space +(not an instruction). As the examples show, a space is put between the +backslash and the start of the next instruction. +

+Sample Source Listing.

+Some examples of valid source statements follow (6502 mnemonics shown): +
  lab1       lda    byte1   ;get the first byte
+             dec    byte1
+             jne    label1
+  ;            
+  lab2       sta    byte2,X
+  ;  a multiple statement line follows
+             lda    byte1\ sta byte1+4\ lda byte2\ sta byte2+4
+ +
+

+EXPRESSIONS

+Expressions are made up of various syntactic elements combined according +to a set of syntactical rules. Expressions can be comprised of the following +elements: +
    +
  • +Labels
    • + +
  • +Constants
    • + +
  • +Location Counter Symbol
    • + +
  • +Operators
    • + +
  • +Parenthesis
    • +
+ +

+Labels

+Labels are strings of characters that have a numeric value associated with +them, generally representing an address. Labels can contain upper and lower +case letters, digits, underscores, and periods. The first character must +be a letter or the local label prefix (default '_'). The value of a label +is limited to 32 bit precision. Labels can contain up to 32 characters, +all of which are significant (none are ignored when looking at a label's +value, as in some assemblers). Case is significant unless the '-i' command +line option is invoked. + +

Local labels must only be unique within the scope of the current module. +Modules are defined with the MODULE directive. Here +is an example: +

          .MODULE xxx
+          lda regx
+          jne _skip
+          dec
+   _skip  rts
+          .MODULE yyy
+          lda regy
+          jne _skip
+          dec
+   _skip  rts
+In the above example, the _skip label is reused without harm. As +a default, local labels are not shown in the label table listing (resulting +from the '-l' command line option). See also sections on MODULE +and LOCALLABELCHAR directives. +

+Numeric Constants

+Numeric constants must always begin with a decimal digit (thus hexadecimal +constants that start with a letter must be prefixed by a '0' unless the +'$' prefix is used). The radix is determined by a letter immediately following +the digit string according to the following table: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Radix Suffix Prefix 
2 B or b % 
8 O or o @ 
10 D or d (or nothing) 
16 H or h $ 
+ +

Decimal is the default radix, so decimal constants need no suffix or prefix. + +

The following representations are equivalent: +

    1234H          or     $1234
+    100d           or     100
+    177400o        or     @177400
+    01011000b      or     %01011000
+The prefixes are provided for compatibility with some other source code +formats but introduce a problem of ambiguity. Both '%' and '$' have alternate +uses ('%' for modulo, '$' for location counter symbol). The ambiguity is +resolved by examining the context. The '%' character is interpreted as +the modulo operator only if it is in a position suitable for a binary operator. +Similarly, if the first character following a '$' is a valid hexadecimal +digit, it is assumed to be a radix specifier and not the location counter. +

+Character Constants

+Character constants are single characters surrounded by single quotes. +The ASCII value of the character in the quotes is returned. No escape provision +exists to represent non-printable characters within the quotes, but this +is not necessary since these can be just as easily represented as numeric +constants (or using the TEXT directive which does allow +escapes). +

+String Constants.

+String constants are one or more characters surrounded by double quotes. +Note that string constants are not allowed in expressions. They are only +allowable following the TITLE, BYTE, +DB, and TEXT assembler directives. +The quoted strings may also contain escape sequences to put in unprintable +values. The following escape sequences are supported: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Escape Sequence Description 
\n Line Feed 
\r Carriage return 
\b Backspace 
\t Tab 
\f Formfeed 
\\ Backslash 
\" Quote 
\000 Octal value of character 
+ +

+Location Counter Symbol

+The current value of the location counter (PC) can be used in expressions +by placing a '$' in the desired place. The Location Counter Symbol is allowable +anywhere a numeric constant is. (Note that if the '$' is followed by a +decimal digit then it is taken to be the hexadecimal radix indicator instead +of the Location Counter symbol, as mentioned above). The '*' may also be +used to represent the location counter, but is less preferred because of +its ambiguity with the multiplicative operator. +

+Operators

+Expressions can optionally contain operators to perform some alterations +or calculations on particular values. The operators are summarized as follows: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Operator Type Description 
+ Additive addition 
- subtraction 
* Multiplicative multiplication

% modulo 
<<logical shift left

<less than 
>greater than 
<= less than or equal 
>= greater than or equal 
&Binary binary 'and' 
| binary 'or' 
^ binary 'exclusive or' 
+ +

The syntax is much the same as in ANSI C with the following notes: + +

    +
  1. +No operator precedence is in effect. Evaluation is from left to right unless +grouped by parenthesis (see example below).
    2. + +
  2. +All evaluations are done with 32 bit signed precision.
    3. + +
  3. +Both '=' and '==' are allowable equality checkers. This is allowed since +the syntax does not provide assignment capability (as '=' would normally +imply).
    4. +
+The relational operators return a value of 1 if the relation is true and +0 if it is false. Thirty-two bit signed arithmetic is used. + +

It is always a good idea to explicitly indicate the desired order of +evaluation with parenthesis, especially to maintain portability since TASM +does not evaluate expressions in the same manner as many other assemblers. +To understand how it does arrive at the values for expressions, consider +the following example: +

    1 + 2*3 + 4
+TASM would evaluate this as: +
    (((1 + 2) * 3) + 4) = 13
+Typical rules of precedence would cause the (2*3) to be evaluated first, +such as: +
    1 + (2*3) + 4      = 11
+To make sure you get the desired order of evaluation, use parenthesis liberally. +Here are some examples of valid expressions: +
    (0f800H + tab)
+    (label_2 >> 8)
+    (label_3 << 8) & $f000
+    $ + 4
+    010010000100100b + 'a'
+    (base + ((label_4 >> 5) & (mask << 2))
+ +
+

+ASSEMBLER DIRECTIVES

+Most of the assembler directives have a format similar to the machine instruction +format. However, instead of specifying operations for the processor to +carry out, the directives cause the assembler to perform some function +related to the assembly process. TASM has two types of assembler directives +- those that mimic the 'C' preprocessor functions, and those that resemble +the more traditional assembler directive functions. Each of these will +be discussed. + +

The ANSI C preprocessor style directives are invoked with a '#' as the +first character of the line followed by the appropriate directive (just +as in 'C'). Thus, these directives cannot have a label preceding them (on +the same line). Note that in the examples directives are shown in upper +case, however, either upper or lower case is acceptable. +

+ADDINSTR

+The ADDINSTR directive can be used to define additional instructions for +TASM to use in this assembly. The format is: +
    [label] .ADDINSTR inst args opcode nbytes rule class shift binor
+The fields are separated by white space just as they would appear in an +instruction definition file. See the TASMTABS.HTM file on the TASM distribution +disk for more detail. +

+AVSYM

+See SYM/AVSYM. +

+BLOCK

+The BLOCK directive causes the Instruction Pointer to advance the specified +number of bytes without assigning values to the skipped over locations. +The format is: +
    [label] .BLOCK        expr
+Some valid examples are: +
    word1   .BLOCK     2
+    byte1   .block     1
+    buffer  .block     80
+ +

+BSEG/CSEG/DSEG/NSEG/XSEG

+These directives can be invoked to indicate the appropriate address space +for symbols and labels defined in the subsequent code. The invocation of +these directives in no way affects the code generated, only provides more +information in the symbol table file if the AVSYM directive is employed. +Segment control directives such as these are generally supported by assemblers +that generate relocatable object code. TASM does not generate relocatable +object code and does not support a link phase, so these directives have +no direct effect on the resulting object code. The segments are defined +as follows: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Directive Segment Description 
BSEG Bit address 
CSEG Code address 
DSEG Data address (internal RAM) 
NSEG Number or constant (EQU) 
XSEG External data address (external RAM) 
+ +

+BYTE

+The BYTE directive allows a value assignment to the byte pointed to by +the current Instruction Pointer. The format is: +
    [label] .BYTE   expr [, expr ...]
+Only the lower eight bits of expr are used. Multiple bytes may be +assigned by separating them with commas or (for printable strings) enclosed +in double quotes. Here are some examples: +
    label1   .BYTE     10010110B
+             .byte     'a'
+             .byte     0
+             .byte     100010110b,'a',0
+             .byte     "Hello", 10, 13, "World"
+ +

+CHK

+The CHK directive causes a checksum to be computed and deposited at the +current location. The starting point of the checksum calculation is indicated +as an argument. Here is the format: +
    [label]    .CHK    starting_addr
+Here is an example: +
    start: NOP
+           LDA #1
+           .CHK start
+The checksum is calculated as the simple arithmetic sum of all bytes starting +at the starting_addr up to but not including the address of the +CHK directive. The least significant byte is all that +is used. +

+CODES/NOCODES

+The CODES/NOCODES directives can be used to alternately turn on or off +the generation of formatted listing output with line numbers, opcodes, +data, etc. With NOCODES in effect, the source lines are sent to the listing +file untouched. This is useful around blocks of comments that need a full +80 columns of width for clarity. +

+DB

+This is alternate form of the BYTE directive. +

+DW

+This is alternate form of the WORD directive. +

+DEFINE

+The DEFINE directive is one of the most powerful of the directives and +allows string substitution with optional arguments (macros). The format +is as follows: +
    #DEFINE  macro_label[(arg_list)]  [macro_definition]
+Where: +
+
+macro_label
+ +
+character string to be expanded when found in the source file
+ +
+arg_list
+ +
+optional argument list for variable substitution in macro expansion
+ +
+macro_def
+ +
+string to replace the occurrences of macro_label in the source file.
+
+The simplest form of the DEFINE directive might look like this: +
    #DEFINE         MLABEL
+Notice that no substitutionary string is specified. The purpose of a statement +like this would typically be to define a label for the purpose of controlling +some subsequent conditional assembly (IFDEF or IFNDEF). + +

A more complicated example, performing simple substitution, might look +like this: +

    #DEFINE         VAR1_LO         (VAR1 & 255)
+This statement would cause all occurrences of the string 'VAR1_LO' in the +source to be substituted with '(VAR1 & 255)'. + +

As a more complicated example, using the argument expansion capability, +consider this: +

    #DEFINE  ADD(xx,yy)    clc\ lda xx\ adc yy\ sta xx
+If the source file then contained a line like this: +
    ADD(VARX,VARY)
+It would be expanded to: +
    clc\ lda VARX\ adc VARY\ sta VARX
+The above example shows the use of the backslash ('\') character as a multiple +instruction statement delimiter. This approach allows the definition of +fairly powerful, multiple statement macros. The example shown generates +6502 instructions to add one memory location to another. + +

Some rules associated with the argument list: +

    +
  1. +Use a maximum of 10 arguments.
    2. + +
  2. +Each argument should be a maximum of 15 characters.
    3. +
+Note that macros can be defined on the TASM command line, also, with the +-d option flag. +

+DEFCONT

+The DEFCONT directive can be used to add to the last macro started with +a DEFINE directive. This provides a convenient way +to define long macros without running off the edge of the page. The ADD +macro shown above could be defined as follows: +
    #DEFINE         ADD(xx,yy)     clc
+    #DEFCONT                     \ lda xx
+    #DEFCONT                     \ adc yy
+    #DEFCONT                     \ sta xx
+ +

+ECHO

+The ECHO directive can be used to send output to the console (stderr). +It can accept either a quoted text string (with the standard escape sequences +allowed) or a valid expression. It can accept only one or the other, however. +Multiple instances of the directive may be used to create output that contains +both. Consider the following example: +
    .ECHO "The size of the table is "
+    .ECHO (table_end - table_start)
+    .ECHO " bytes long.\n"
+This would result in a single line of output something like this: +
    The size of the table is 196 bytes long.
+ +

+EJECT

+The EJECT directive can be used to force a top-of-form and the generation +of a page header on the list file. It has no effect if the paging mode +is off (see PAGE/NOPAGE). The format is: +
    [label]    .EJECT
+ +

+ELSE

+The ELSE directive can optionally be used with IFDEF, IFNDEF and IF to +delineate an alternate block of code to be assembled if the block immediately +following the IFDEF, IFNDEF or IF is not assembled. + +

Here are some examples of the use of IFDEF, IFNDEF, IF, ELSE, and ENDIF: +

    #IFDEF   label1
+        lda      byte1
+        sta      byte2
+    #ENDIF   
+
+    #ifdef   label1
+        lda      byte1
+    #else    
+        lda      byte2
+    #endif   
+
+    #ifndef  label1
+        lda      byte2
+    #else    
+        lda      byte1
+    #endif   
+
+    #if ($ >= 1000h)
+    ; generate an invalid statement to cause an error
+    ;  when we go over the 4K boundary.
+    !!! PROM bounds exceeded.
+    #endif
+ +

+END

+The END directive should follow all code/data generating statements in +the source file. It forces the last record to be written to the object +file. The format is: +
    [label]       .END [addr]
+The optional addr will appear in the last object record (Motorola +S9 record type) if the object format is Motorola hex. The addr field +is ignored for all other object formats. +

+ENDIF

+The ENDIF directive must always follow an IFDEF, IFNDEF, or IF directive +and signifies the end of the conditional block. +

+EQU

+The EQU directive can be used to assign values to labels. The labels can +then be used in expressions in place of the literal constant. The format +is: +
    label   .EQU   expr
+Here is an example: +
    MASK   .EQU  0F0H
+    ;
+           lda   IN_BYTE
+           and   MASK
+           sta   OUT_BYTE
+An alternate form of the EQU directive is '='. The previous example is +equivalent to any of the following: +
    MASK    =   0F0H
+    MASK    =0F0H
+    MASK    =$F0
+White space must exist after the label, but none is required after +the '='. +

+EXPORT

+The EXPORT directive can be used to define labels (symbols) that are to +be written to the export symbol file. The symbols are written as equates +(using the .EQU directive) so that the resulting file can be included in +a subsequent assembly. This feature can help overcome some of the deficiencies +of TASM due to its lack of a relocating linker. The format is: +
    [label]  .EXPORT      label [,label...]
+The following example illustrates the use of the EXPORT directive and the +format of the resulting export file: + +

Source file: +

    EXPORT        read_byte
+    EXPORT        write_byte, open_file
+Resulting export file: +
    read_byte      .EQU   $1243
+    write_byte     .EQU   $12AF
+    open_file      .EQU   $1301
+ +

+FILL

+The FILL directive can be used to fill a selected number of object bytes +with a fixed value. Object memory is filled from the current program counter +forward. The format is as follows: +
    [label]  .FILL      number_of_bytes [,fill_value]
+The number_of_bytes value can be provided as any valid expression. +The optional fill_value can also be any valid expression. If fill_value +is not provided, a default value of 255 ($FF) is used. +

+IFDEF

+The IFDEF directive can be used to optionally assemble a block of code. +It has the following form: +
    #IFDEF  macro_label
+When invoked, the list of macro labels (established via DEFINE +directives) is searched. If the label is found, the following lines of +code are assembled. If not found, the input file is skipped until an ENDIF +or ELSE directive is found. + +

Lines that are skipped over still appear in the listing file, but a +'~' will appear immediately after the current PC and no object code will +be generated (this is applicable to IFDEF, IFNDEF, and IF). +

+IFNDEF

+The IFNDEF directive is the opposite of the IFDEF directive. The block +of code following is assembled only if the specified macro_label +is undefined. It has the following form: +
    #IFNDEF  macro_label
+When invoked, the list of macro labels (established via DEFINE directives) +is searched. If the label is not found, the following lines of code are +assembled. If it is found, the input file is skipped until an ENDIF or +ELSE directive is found. +

+IF

+The IF directive can be used to optionally assemble a block of code dependent +on the value of a given expression. The format is as follows: +
    #IF     expr
+If the expression expr evaluates to non-zero, the following block +of code is assembled (until an ENDIF or ELSE is encountered). +

+INCLUDE

+The INCLUDE directive reads in and assembles the indicated source file. +INCLUDEs can be nested up to four levels. This allows a convenient means +to keep common definitions, declarations, or subroutines in files to be +included as needed. The format is as follows: +
#INCLUDE        filename
+The filename must be enclosed in double quotes. Here are some examples: +
    #INCLUDE       "macros.h"
+    #include       "equates"
+    #include       "subs.asm"
+ +

+LIST/NOLIST

+The LIST and NOLIST directives can be used to alternately turn the output +to the list file on (LIST) or off (NOLIST). The formats are: +
    .LIST
+    .NOLIST
+ +

+LOCALLABELCHAR

+The LOCALLABELCHAR directive can be used to override the default "_" as +the label prefix indicating a local label. For example, to change the prefix +to "?" do this: +
    [label]   .LOCALLABELCHAR "?"
+Be careful to use only characters that are not operators for expression +evaluation. To do so causes ambiguity for the expression evaluator. Some +safe characters are "?", "{", and "}".  See Labels +for an example of local label usage. +

+LSFIRST/MSFIRST

+The LSFIRST and MSFIRST directives determine the byte order rule to be +employed for the WORD directive. The default (whether +correct or not) for all TASM versions is the least significant byte first +(LSFIRST). The following illustrates its effect: +
    0000  34 12    .word $1234
+    0002           .msfirst
+    0002  12 34    .word $1234
+    0004           .lsfirst
+    0004  34 12    .word $1234
+ +

+MODULE

+The MODULE directive defines the scope of local labels. The format is: +
    [label]   .MODULE label
+Here is an example: +
          .MODULE module_x
+          lda regx
+          jne _skip
+          dec
+   _skip  rts
+          .MODULE module_y
+          lda regy
+          jne _skip
+          dec
+   _skip  rts
+In the above example, the local label _skip is reused without harm +since the two usages are in separate modules. See also section LOCALLABELCHAR +directive. +

+ORG

+The ORG directive provides the means to set the Instruction Pointer (a.k.a. +Program Counter) to the desired value. The format is: +
    [label] .ORG    expr
+The label is optional. The Instruction pointer is assigned the value +of the expr. For example, to generate code starting at address 1000H, +the following could be done: +
    start   .ORG    1000H
+The expression (expr) may contain references to the current Instruction +Pointer, thus allowing various manipulations to be done. For example, to +align the Instruction Pointer on the next 256 byte boundary, the following +could be done: +
    .ORG  (($ + 0FFH) & 0FF00H)
+ORG can also be used to reserve space without assigning values: +
    .ORG    $+8
+An alternate form of ORG is '*=' or '$='. Thus the following two examples +are exactly equivalent to the previous example: +
    *=*+8
+    $=$+8
+ +

+PAGE/NOPAGE

+The PAGE/NOPAGE directives can be used to alternately turn the paging mode +on (PAGE) or off (NOPAGE). If paging is in effect, then every sixty lines +of output will be followed by a Top of Form character and a two line header +containing page number, filename, and the title. The format is: +
    
+    .PAGE
+    .NOPAGE
+The number of lines per page can be set with the '-p' command line option. +

+SET

+The SET directive allows the value of an existing label to be changed. +The format is: +
    label   .SET    expr
+The use of the SET directive should be avoided since changing the value +of a label can sometimes cause phase errors between pass 1 and pass 2 of +the assembly. +

+SYM/AVSYM

+These directives can be used to cause a symbol table file to be generated. +The format is: +
    .SYM    ["symbol_filename"]
+    .AVSYM  ["symbol_filename"]
+For example: +
    .SYM       "symbol.map"
+    .SYM       
+    .AVSYM     "prog.sym"
+    .AVSYM
+The two directives are similar, but result in a different format of the +symbol table file. The format of the SYM file is one line per symbol, each +symbol starts in the first column and is followed by white space and then +four hexadecimal digits representing the value of the symbol. The following +illustrates the format: +
    label1         FFFE
+    label2         FFFF
+    label3         1000
+The AVSYM directive is provided to generate symbol tables compatible with +the Avocet 8051 simulator. The format is similar, but each line is prefixed +by an 'AS' and each symbol value is prefixed by a segment indicator: +
    AS     start          C:1000
+    AS     read_byte      C:1245
+    AS     write_byte     C:1280
+    AS     low_nib_mask   N:000F
+    AS     buffer         X:0080
+The segment prefixes are determined by the most recent segment directive +invoked (see BSEG/CSEG/DSEG/NSEG/XSEG directives). +

+TEXT

+This directive allows an ASCII string to be used to assign values to a +sequence of locations starting at the current Instruction Pointer. The +format is: +
    [label] .TEXT   "string"
+The ASCII value of each character in string is taken and assigned to the +next sequential location. Some escape sequences are supported as follows: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

Here are some examples: + +

    message1   .TEXT   "Disk I/O error"
+    message2   .text   "Enter file name "
+               .text   "abcdefg\n\r"
+               .text   "I said \"NO\""
+ +

+TITLE

+The TITLE directive allows the user to define a title string that appears +at the top of each page of the list file (assuming the PAGE mode is on). +The format is: +
    [label]    .TITLE  "string"
+The string should not exceed 80 characters. Here are some examples: +
    .TITLE  "Controller version 1.1"
+    .title  "This is the title of the assembly"
+    .title  ""
+ +

+WORD

+The WORD directive allows a value assignment to the next two bytes pointed +to by the current Instruction Pointer. The format is: +
    [label] .WORD expr [,expr...]
+The least significant byte of expr is put at the current Instruction Pointer +with the most significant byte at the next sequential location (unless +the MSFIRST directive has been invoked). Here are some examples: +
    data_table     .WORD   (data_table + 1)
+                   .word   $1234
+                   .Word   (('x' - 'a')  << 2)
+                   .Word  12, 55, 32

+

+OBJECT FILE FORMATS

+TASM can generate object code in the formats indicated below: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
Option Description
-g0 Intel hex (default) 
-g1 MOS Technology hex (same as -m) 
-g2 Motorola hex 
-g3 binary (same as -b) 
-g4 Intel hex with word addresses
+

The -m and -b flags may also be used, as indicated above. +If both are used the right-most option on the command line will be obeyed. +

+Intel Hex Object Format

+This is the default object file format. This format is line oriented and +uses only printable ASCII characters except for the carriage return/line +feed at the end of each line. The format is symbolically represented as: + +

:NN AAAA RR HH CC CRLF + +

Where: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
:Record Start Character (colon)
NNByte Count (2 hex digits)
AAAAAddress of first byte (4 hex digits)
RRRecord Type (00 except for last record +which is 01)
HHData Bytes (a pair of hex digits for each byte +of data in the record)
CCCheck Sum (2 hex digits)
CRLFLine Terminator (CR/LF for DOS, LF for LINUX)
+

The last line of the file will be a record conforming to the above format +with a byte count of zero. + +

The checksum is defined as: + +

sum = byte_count+address_hi+address_lo+record_type+(sum of all data +bytes) +
checksum = ((-sum) & ffh) + +

Here is a sample listing file followed by the resulting object file: +

0001   0000             
+0002   1000                     .org   $1000
+0003   1000 010203040506        .byte  1, 2, 3, 4, 5, 6, 7, 8
+0003   1006 0708
+0004   1008 090A0B0C0D0E        .byte  9,10,11,12,13,14,15,16

+    :02101800191AA3
+    :00000001FF
+ +

+Intel Hex Word Address Object Format

+This format is identical to the Intel Hex Object Format except that +the address for each line of object code is divided by two thus converting +it to a word address (16 bit word). All other fields are identical. + +

Here is an example: +

:180800000102030405060708090A0B0C0D0E0F101112131415161718AC
+:02080C00191AA3
+:00000001FF
+ +

+MOS Technology Hex Object Format

+This format is line oriented and uses only printable ASCII characters except +for the carriage return/line feed at the end of each line. Each line in +the file is of the following format: + +

:NN AAAA HH CC CRLF + +

Where: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
;Record Start Character (semicolon)
NNByte Count (2 hex digits)
AAAAAddress of first byte (4 hex digits)
HHData Bytes (a pair of hex digits for each byte +of data in the record)
CCCCCheck Sum (4 hex digits)
CRLFLine Terminator (CR/LF for DOS, LF for LINUX)
+

The last line of the file will be a record conforming to the above format +with a byte count of zero. + +

The checksum is defined as: + +

sum =byte_count+address_hi+address_lo+record_type+(sum of all data +bytes) +
checksum = (sum & ffffh) + +

Here is a sample object file: +

;1810000102030405060708090A0B0C0D0E0F1011121314151617180154
+;021018191A005D
+;00
+ +

+Motorola Hex Object Format

+This format is line oriented and uses only printable ASCII characters except +for the carriage return/line feed at the end of each line. The format is +symbolically represented as: + +

S1 NN AAAA HH CCCC CRLF + +

Where: +
  + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
S1Record Start tag 
NNByte Count (2 hex digits) (data byte count + +3)
AAAAAddress of first byte (4 hex digits)
HHData Bytes (a pair of hex digits for each byte +of data in the record)
CCCheck Sum (2 hex digits)
CRLFLine Terminator (CR/LF for DOS, LF for LINUX)
+ +

The checksum is defined as: + +

sum = byte_count+address_hi+address_lo+(sum of all data bytes) +
checksum = ((~sum) & ffh) + +

Here is a sample file: +

S11B10000102030405060708090A0B0C0D0E0F101112131415161718A8
+S1051018191A9F
+S9030000FC
+

The last line of the file will be a record with a byte count of zero and +a tag of S9. The address field will be 0000 unless and address was provided +with the END directive in which case it will appear in the address field. +

+Binary Object Format.

+This file format is essentially a memory image of the object code without +address, checksum or format description information. + +

Note that when this object format is selected (-b option), the -c option +is forced. This is done so that no ambiguity results from the lack of address +information in the file. Without the -c option, discontinuous blocks of +object code would appear contiguous. +
  + +

+

+

+LISTING FILE FORMAT

+Each line of source code generates one (or more) lines of output in the +listing file. The fields of the output line are as follows: +
    +
  1. +Current source file line number (4 decimal digits).
    2. + +
  2. +An optional '+' appears if this is an 'INCLUDE' file. (One '+' for each +level of INCLUDE invoked).
    3. + +
  3. +Current Instruction Pointer (4 hex digits). An optional '~' follows the +Instruction Pointer if the line of source code is not being assembled because +of an IFDEF, IFNDEF, or IF directive.
    4. + +
  4. +Resulting code/data generated from this source line (two hex digits per +byte, each byte separated by a space, up to six bytes per line).
    5. + +
  5. +The source line exactly as it appears in the source file.
    6. +
+If paging is enabled (by either the '-p' option flag or the .PAGE directive) +some additional fields will be inserted into the listing file every 60 +lines. These fields are: +
    +
  1. +Top of Form (form feed).
    2. + +
  2. +Assembler identifier (e.g. "TASM 6502 Assembler").
    3. + +
  3. +Initial source file name.
    4. + +
  4. +Page number.
    5. + +
  5. +Title.
    6. +
+If errors are encountered, then error messages will be interspersed in +the listing. TASM outputs error messages proceeding the offending line. +The following example illustrates the format: +
    0001   0000             label1  .equ  40h
+    0002   0000             label2  .equ  44h
+    0003   0000 
+    0004   1000             start:  .org  1000h
+    0005   1000 E6 40               inc   label1
+    0006   1002 E6 44               inc   label2
+    tt.asm line 0007: Label not found: (label3)
+    0007   1004 EE 00 00            inc   label3
+    0008   1007 4C 00 10            jmp   start
+    0009   100A                     .end  
+    0010   100A                            
+    tasm: Number of errors = 1
+ +
+

+PROM PROGRAMMING

+A wide variety of PROM programming equipment is available that can use +object code in one or more of the formats supported by TASM. Here are some +notes concerning the generation of code to be programmed into PROMs: +

+PRESET MEMORY

+It is often desirable to have all bytes in the PROM programmed even if +not explicitly assigned a value in the source code (e.g. the bytes are +skipped over with a .ORG statement). This can be accomplished by using +the -c (contiguous block) and the -f (fill) command line +option flags. The -c will ensure that every byte from the lowest +byte assigned a value to the highest byte assigned a value will be in the +object file with no gaps. The -f flag will assign the specified +value to all bytes before the assembly begins so that when the object file +is written, all bytes not assigned a value in the source code will have +a known value. As an example, the following command line will generate +object code in the default Intel Hex format with all bytes not assigned +a value in the source set to EA (hex, 6502 NOP instruction): +
    tasm -65 -c -fEA test.asm
+ +

+CONTIGUOUS BLOCKS

+To ensure that TASM generates object code to cover the full address range +of the target PROM, put a .ORG statement at the end of the source file +set to the last address desired. For example, to generate code to be put +in a 2716 EPROM (2 Kbytes) from hex address $1000 to $17ff, do something +like this in the source file: +
    ;start of the file
+        .ORG    $1000
+    ;rest of the source code follows
+    source code
+    ;end of the source code
+        .ORG    $17ff
+        .BYTE   0
+        .END
+Now, to invoke TASM to generate the code in the binary format with all +unassigned bytes set to 00 (6502 BRK instruction), do the following: +
tasm -65 -b -f00 test.asm
+Note: -b forces the -c option. +
+
+

+ERROR MESSAGES

+ +

+Error Message Format

+TASM error messages take the following general form: +
    filename line line_number: error_message
+For example: +
    main.asm line 0032: Duplicate label (start)
+Many editors and IDE’s can run assemblies from within and parse the error +messages to make it convenient to jump to each error and correct.  +If the above format is not satisfactory for your editor or IDE, use the +TASMERRFORMAT environment variable to alter +the error message format. + +

When using automatic invocation of TASM from within an editor or IDE, +it may be useful to use the TASMOPTS environment +variable to set other command line options.  For example, to cause +TASM to perform 6502 assemblies, set TASMOPTS like this: +

    +
    SET TASMOPTS=-65
    +
+ +

+ERROR MESSAGE DESCRIPTIONS

+ +
+
+Binary operator where value expected
+ +
+Two binary operators in a row indicate a missing value.
+ +
+Branch off of current 2K page
+ +
+An instruction is attempting to branch to a location not within the current +2K byte page.
+ +
+Branch off of current page
+ +
+An instruction is attempting to branch to a location not within the current +256 byte page.
+ +
+Cannot malloc for label storage
+ +
+Insufficient memory to store more labels. See LIMITATIONS.
+ +
+Duplicate label
+ +
+The label for the current line has already been assigned a value. Duplicate +label checks are optionally enabled by the -a option.
+ +
+File name too short
+ +
+A file name on the command line is fewer than 3 characters. A two character +file name may be valid, of course, but it is detected as an error to prevent +a garbled option flag from being taken as a source file, which in turn +can result in the true source file being taken as the object file. Since +the object file is truncated at startup time, the source file could be +clobbered.
+ +
+Forward reference in equate
+ +
+An EQU directive is using a label on the right hand side that has not yet +been defined.
+ +
+Heap overflow on label definition
+ +
+TASM was unable to allocate memory to store the label.
+ +
+Imbalanced conditional.
+ +
+An end-of-file was encountered at which time the level of descent in conditional +directives was different from when the file was entered. Conditional directives +include IF, IFDEF, and IFNDEF.
+ +
+Invalid Object file type.
+ +
+An object file type was requested by the -g command line option that is +not valid. See section on Option g - Object File Format.
+ +
+Invalid operand.
+ +
+No indirection for this instruction. The first character of an operand +was a left parenthesis for an instruction that does not explicitly specify +that as the format. Some micros use the parenthesis as an indicator of +indirection, but putting a layer of parenthesis around an expression is +always a valid thing to do (as far as the expression evaluator is concerned). +The test for this case is only done if the -a4 option is selected. +See section on ASSEMBLY CONTROL.
+ +
+Invalid token where value expected.
+ +
+Two binary operators in a row are not allowed.
+ +
+Label too long.
+ +
+Labels are limited to 31 characters.
+ +
+Label value misaligned
+ +
+The value of a label appears to have a different value on the second pass +then it was computed to have on the first pass. This is generally due to +Zero Page Addressing mode problems with the 6502 version of TASM. Labels +that are used in operands for statements that could utilize Zero Page addressing +mode should always be defined before used as an operand.
+ +
+Label not found
+ +
+A label used in an expression was not found in the current label table.
+ +
+Label must pre-exist for SET.
+ +
+The SET directive can only be applied to an existing label.
+ +
+Label table overflow
+ +
+To many labels have been encountered.
+ +
+List file open error
+ +
+TASM was not able to open the specified list file.
+ +
+Macro expansion too long.
+ +
+The expansion of a macro resulted in a line that exceeded the maximum length.
+ +
+Max number of nested conditionals exceeded
+ +
+Too many levels of IF, IFDEF, or IFNDEF.
+ +
+Maximum number of args exceeded
+ +
+Too many macro arguments.
+ +
+Maximum number of macros exceeded
+ +
+Too many macros (DEFINEs) have been encountered.
+ +
+No END directive before EOF
+ +
+The source file did not have an END directive in it. This is not fatal, +but may cause the last object file record to be lost.
+ +
+No files specified
+ +
+TASM was invoked with no source file specified.
+ +
+No such label
+ +
+A SET directive was encountered for a label not yet defined. The value +of labels that are modified by the SET directive must already exist.
+ +
+No terminating quote
+ +
+A double quote was used at the start of a a text string but was not used +at the end of the string.
+ +
+No indirection for this instruction.
+ +
+A parenthesis was found around the operand expression. This may indicate +an attempt to use indirection where it is inappropriate.
+ +
+Non-unary operator at start of expression
+ +
+A binary operator (such as '*') was found at the beginning of an expression. +Some micros use '*' as an indirection operator. Since it is also a legitimate +operator in an expression, some ambiguity can arise. If a particular instruction/addressing +mode does not allow indirection, and a '*' is placed in front of the associated +expression, the assembler will assume this error. See the -a8 option +of ASSEMBLY CONTROL.
+ +
+Object file open error
+ +
+TASM was not able to open the specified object file.
+ +
+Range of argument exceeded
+ +
+The value of an argument exceeds the valid range for the current instruction +and addressing mode.
+ +
+Range of relative branch exceeded
+ +
+A branch instruction exceeds the maximum range.
+ +
+Source file open error
+ +
+TASM was not able to open the specified source file.
+ +
+Unrecognized directive
+ +
+A statement starting with a '.' or '#' has a mnemonic that is not defined +as a directive.
+ +
+Unrecognized instruction
+ +
+A statement has an opcode mnemonic that is not defined.
+ +
+Unrecognized argument
+ +
+A statement has an operand format that is not defined.
+ +
+Unknown token
+ +
+Unexpected characters were encountered while parsing an expression.
+ +
+Unused data in MS byte of argument
+ +
+An instruction or directive used the least significant byte of an argument +and left the most significant byte unused, but it was non-zero.
+ +
+Unknown option Flag.
+ +
+Invalid option flag has been specified on the command line. invoke TASM +with nothing on the command line to see a list of valid options.

TASM TABLE SYNTAX DESCRIPTION

+

The tables that control TASM's interpretation of the source file are read +from a file at run time. The table file name is determined by taking the +numeric option field specified on the TASM command line and appending it to the +string "TASM", then a ".TAB" extension is added. Thus, +if the following command line is entered: +

+
        tasm -51  test.asm
+
+

then TASM would read the table file named "TASM51.TAB". +

+

The following rules apply to the structure of the table file: +

+
    +
  • The first line of the file should contain a string surrounded by double +quotes that should identify the version of the assembler table. This string +will appear at the top of each page in the list file. It should be limited to +24 characters.
    • +
  • Any line that starts with a '.' is considered a directive. Directives +should preceed instruction defintion lines. The following directives are +available: +
+ + + + + + + + + + + + + + + + + + +
DIRECTIVEDESCRIPTION
MSFIRSTGenerate opcodes MS byte first. Useful for tables with multibyte opcodes.
ALTWILDUse '@' instead of '*' as the wild card in the table. Useful if the +instruction syntax uses '*' to denote certain addressing modes.
NOARGSHIFTSuppress the shift/or operation that applies if the optional SHIFT and OR +fields are provided. Some RULEs use the SHIFT/OR fields for other purposes.
REGSETDefine a register mnemonic and associated bit field. See example below.
WORDADDRSSet word addressing mode (one word = 2 bytes)
+
    +
  • Any line whose first character is not a '.' and is not alphabetic is +considered to be a comment and is discarded.
    • +
  • Any line that has an alphabetic character as the first character is assumed +to be an instruction definition record and is parsed to build the internal +representation of the instruction set tables. Eight fields (separated by white +space) are expected, as follows: +
+ + + + + + + + + + + + + + + + + + + + + + + + + + + +
Field Name Description
INSTRUCTION Instruction Mnemonic
ARGS Argument definition
OPCODE Opcode value
NBYTES Number of bytes
RULE Modifier operation
CLASS Instruction class
SHIFT Argument left shift count
OR Argument bitwise OR mask
+

The fields are further defined below:

+
+
INSTRUCTION
+
The INSTRUCTION field should contain the string to be used as the mnemonic +for this instruction. Upper case letters should be used (the source statements +are converted to upper case before comparison).
+
ARGS.
+
The ARGS field should contain a string describing the format of the operand +field. All characters are taken literally except the '*' which denotes the +presence of a valid TASM expression. Multiple '*'s can be used, but all but the +last one must be followed by a comma, '[', or ']'. If a single '*' appears in +the ARGS field, then the default action of TASM will be to determine the value +of the expression that matches the field and insert one or two bytes of it into +the object file depending on the NBYTES field. If multiple '*'s are used, then +special operators (RULE) must be used to take advantage of them (see the +examples below). An ARGS field of a pair of double quotes means that no +arguments are expected. +
+
OPCODE.
+
The OPCODE field should contain the opcode value (two to six hex digits) +for this instruction and address mode. Each pair of hex digits represent a +single byte of the opcode, ordered with the right most pair being placed in the +lowest memory location. +
+
NBYTES.
+
The NBYTES field should specify the number of bytes this instruction is to +occupy (a single decimal digit). This number includes both opcode bytes and +argument bytes, thus, the number of bytes of argument is computed by subtracting +the number of bytes of opcode (dictated by the length of the OPCODE field) from +NBYTES. +
+
RULE.
+
The RULE field determines if any special operations need to be performed +on the code generated for this instruction. For example, the zero-page +addressing mode of the 6502 is a special case of the absolute addressing mode, +and is handled by a special RULE code. See the Encoding Rules below. +
+
CLASS.
+
The CLASS field is used to specify whether this instruction is part of the +standard instruction set or a member of a set of extended instructions. Bit 0 of +this field should be set to denote a member of the standard instruction set. +Other bits can be used as needed to establish several classes (or sets) of +instructions that can be enabled or disabled via the '-x' command line option. + +
+
SHIFT (optional).
+
The SHIFT field is used to cause the first argument of the given +instruction to be shifted left the specified number of bits. (Except T1, TDMA, +TAR RULES as noted below). +
+
OR (optional).
+
The OR field is used to perform a bitwise OR with the first argument of the +given instruction. Specified as hex digits. (Except T1, TDMA, TAR RULES as +noted below). +
+

Note that the SHIFT/OR fields are used somewhat differently for T1, TDMA, +and TAR RULES. In those cases, the SHIFT and OR fields are used but the OR +field is really an AND mask and the result is OR'd with the opcode. +

+

Encoding Examples

+

Note that the reason for the combining of arguments (COMBINE and CSWAP) is +that TASM assumes that all object bytes to be inserted in the object file are +derived from a variable representing the value of the first argument (argval). +If two arguments are in the ARGS field, then one of the previously mentioned +RULE`s must be used. They have the effect of combining the low bytes of the +first two arguments into the variable (argval) from which the object code will +be generated. TASM`s argument parsing routine can handle a large number of +arguments, but the code that generates the object code is less capable. +

+

The following table shows possible instruction definition records, followed +by possible source statements that would match it, followed by the resulting +object code that would be generated (in hex): +

+

+
+

The order of the entries for various addressing modes of a given instruction +is important. Since the wild card matches anything, it is important to specify +the ARGS for the addressing modes that have the most qualifying characters +first. For example, if an instruction had two addressing modes, one that +accepted any expression, and another that required a pound sign in front of an +expression, the pound sign entry should go first otherwise all occurrences of +the instruction would match the more general ARGS expression that it +encountered first. The following entries illustrate the proper sequencing: +

+
        ADD #*  12 3 NOTOUCH 1
+        ADD *   13 3 NOTOUCH 1
+
+

Table Lookup Method

+

The current version of TASM uses a very simple hashing method based on the +first character of the nmemonic. A search is begun at the first table entry +that starts with that letter. Thus, the table should be sorted alphabetically +for optimum lookup speed. If the table is not sorted in this way it will not +break anything, but just slow it down a bit.

+

REGSET Directive

+

For instruction sets that have a well defined set of registers that map to a +bit field in the opcode it may be convenient to use the REGSET directive. The +value field following each register definition is OR'd into the opcode when a +match is found. The '!' character is used to indicate the expected occurance of +a register. Consider the following example:

+
.REGSET R0  00 1
+.REGSET R1  01 1
+.REGSET R2  02 1
+.REGSET R3  03 1
+.REGSET R4  04 1
+.REGSET R5  05 1
+.REGSET R6  06 1
+.REGSET R7  07 1
+
+...
+INC !  E0  1 NOP
+...
+
+

A source instruction INC R3 would be encoded by ORing E0 with 03 +resulting in E3.

+
+

6502 INSTRUCTIONS AND ADDRESSING MODES

+

The acceptable 6502 opcode mnemonics for TASM are as follows: +

+
 ADC  AND  ASL  BCC  BCS  BEQ  BNE  BMI  BPL  BVC  BVS  BIT
+ BRK  CLC  CLD  CLI  CLV  CMP  CPX  CPY  DEC  DEX  DEY  EOR
+ INC  INX  INY  JMP  JSR  LDA  LDX  LDY  LSR  NOP  ORA  PHA
+ PHP  PLA  PLP  ROL  ROR  RTI  RTS  SBC  SEC  SED  SEI  STA
+ STX  STY  TAX  TAY  TSX  TXA  TXS  TYA
+
+

TASM also supports the following instructions that are part of the +Rockwell R65C02 and R65C00/21 microprocessor instruction sets. Those that + are marked as set A are applicable to the R65C02 and those marked as set B +are applicable to the R65C00/21 (A+B for both): +

Addressing modes are denoted as follows: +

+
ABS               Absolute
+ZP                Zero Page
+ABS,X             Absolute X
+ZP,X              Zero Page X
+ABS,Y             Absolute Y
+ZP,Y              Zero Page Y
+A                 Accumulator
+(IND,X)           Indirect X
+(IND),Y           Indirect Y
+(IND)             Indirect
+#IMM              Immediate
+REL               Relative (Branch instructions only)
+ZP,REL            Zero Page, Relative
+Implied           Implied
+
+

Note that Zero Page addressing can not be explicitly requested. It is used +if the value of the operand is representable in a single byte for the +applicable statements. +

+

The '-x' command line option can be used to enable the extended +instructions. A '-x' with no digit following will enable the standard set plus +both extended sets. The 6502 version of TASM uses three bits in the instruction +class mask to determine whether a given instruction is enabled or not. Bit 0 +enables the basic set, bit 1 enables set A (R65C02) and bit 2 enables set B +(R65C00/21). The following table shows various options: +

+
Class Mask        Enabled Instructions
+                BASIC   R65C02  R65C00/21
+--------------------------------------------
+1               yes     no      no
+2               no      yes     no
+3               yes     yes     no
+4               no      no      yes
+5               yes     no      yes
+6               no      yes     yes
+7               yes     yes     yes
+
+

Thus, to enable the basic set plus the R65C02 instructions, invoke the +'-x3' command line option. +

+

See manufacturer's data for a more complete description of the meaning of +the mnemonics and addressing modes. +

+
+

68xx INSTRUCTIONS AND ADDRESSING MODES +

+

The following list shows the acceptable opcode mnemonics and their +corresponding operand formats for the 6800/68HC11 version of TASM. Symbolic +fields are defined as follows: +

+
SYMBOLIC            DESCRIPTION
+-----------------------------------------------
+_addr8_             Absolute address (8 bits)
+_addr16_            Absolute address (16 bits)
+                      Values that can fit in 8 bits can
+                      result in the DIRECT addressing mode.
+_addr16_no8_        Absolute address (16 bits)
+                      DIRECT addressing not applicable.
+_bmsk_              Bit mask (8 bits)
+_rel8_              Relative address (8 bit signed)
+_immed8_            Immediate data (8 bits)
+_immed16_           Immediate data (16 bits)
+
+

Any valid TASM expression can appear in the place of any of the above +symbolics. +

+

The lines that are marked with an 'a' or 'b' are extended instructions that +are available only if a -x option has been invoked on the command line. The +classes of instructions (and their bit assignment in the class mask) are shown +below: +

+
BIT     PROCESSOR      EXT LABEL     COMMAND LINE OPTION
+--------------------------------------------------------
+0       6800
+1       6801/6803       a            -x3
+2       68HC11          b            -x7
+
+

Thus, to enable the 68HC11 instructions, a -x7 could be used on the command +line. +

+

TASM deviates from standard Motorola syntax for the BSET, BRSET, BCLR, +and BRCLR instructions. TASM requires commas separating all arguments. +Motorola assemblers use white space to separate the last one or two +arguments for these instructions. Here are examples of each applicable +instruction: +

The following list shows the acceptable opcode mnemonics and their +corresponding operand formats for the 8048 version of TASM. Where 'Rn' is seen, +R0 through R7 may be substituted. Other symbolic fields are as follows: +

+
SYMBOLIC            DESCRIPTION
+-----------------------------------------------
+_addr8_             Absolute address (8 bits)
+_addr11_            Absolute address (11 bits)
+_immed_             Immediate data
+
+
+

Any valid TASM expression can appear in the place of any of the above +symbolics. +

+

The lines that are marked with an (8041), (8022), or (8021) on the far +right are extended instructions that are available only if a -x option has been +invoked on the command line. The classes of instructions (and their bit +assignment in the class mask) are shown below: +

+
BIT     PROCESSOR
+-------------------------------
+0       8X48, 8035, 8039, 8049
+1       8X41A
+2       8022
+3       8021
+
+

Thus, to enable the basic 8048 set plus the 8022 set, a -x5 could be used on +the command line. +

+

Note that some of the base instructions should be disabled for the 8041, +8022, and 8021, but are not. +

TMS7000 INSTRUCTIONS AND ADDRESSING MODES

+

The following list shows the acceptable opcode mnemonics and their +corresponding operand formats for the TMS7000 version of TASM. The following +symbolic fields used in the table: +

+
SYMBOLIC        DESCRIPTION
+-------------------------------------------
+_iop_           Immediate data (8 bits)
+_Rn_            Register file (memory locations 0 to 127 or
+                   0 to 255 depending on on-chip RAM)
+_Pn_            Peripheral file (0-255)
+_rel_           Program address (relative)
+_addr_          Program address (16 bit)
+_trap_          Trap number (0-23)
+
+

Any valid TASM expression can appear in the place of any of the above +symbolics. +

+

Note that TASM allows an alternate syntax for expressing indirection. +Parenthesis can be replaced with brackets (which are less ambiguous because they +do not occur in expressions). Thus, the following are equivalent: +

+
    BR      @addr1(B)
+    BR      @addr1[B]
+

dependent on the setting +# of three variables: CONFIG, ROMSIZE, and CPU: +# +# CONFIG determines which configuration to build which means that +# it will determine the config_xxx.asm config settings file to +# include as well as the output file names. So, for example, +# if CONFIG is "n8vem", the config_n8vem.asm file will be used +# for BIOS configuration settings and the output files will be +# n8vem.rom, n8vem.sys, and n8vem.com. +# +# ROMSIZE specifies the size of the ROM image to be produced and +# currently must be either "1024" for a 1MB ROM or "512" for a +# 512KB ROM. +# +# CPU specifies the instruction set to be used in assembly and +# must be either "80" for Z80 or "180" for Z180. Currently, +# you should use 180 for N8 ROMs and 80 for everything else. +# +# SYS specifies the system variant to build in. CPM will +# build traditional CP/M. ZSYS will build ZSystem which +# currently means ZSDOS 1.2 & ZCPR 1.0 +# +# ROMNAME names the output file. It defaults to +# CONFIG. The output of the build will be: +# .rom, .sys, and .com. +# +# These variables can be passed into the makefile by the command +# line, hardcoded in this file, or set as environment variables +# in the OS. To use a command line, use the following format: +# +# make CONFIG= ROMSIZE= CPU= SYS= ROMNAME= +# +# An example of this is: +# +# make CONFIG=n8vem ROMSIZE=512 CPU=80 SYS=CPM ROMNAME=n8vem +# +# Alternatively, you can specify the variables by hardcoding them +# in this file.
