+INTTEST
+=======
+
+RomWBW includes an API allowing applications to "hook" interrupts.
+The `INTTEST` utility allows you to test this functionality.
+
+
+** Syntax **
+
+`INTTEST`
+
+
+** Usage **
+
+`INTTEST` is an interactive application.  At startup, it will display
+a list of the interrupt vector slots in your system along with the
+current vector address for each of them.
+
+It then prompts you to enter the slot number (in hex) of a vector to
+hook.  After entering this, the application will watch the hooked
+vector and countdown from 0xFF to 0x00 as interrupts are noted.
+
+When the counter reaches 0x00, the interrupt is unhooked and the
+application terminates.  The application can also be terminated by
+pressing <esc>.
+
+
+** Notes **
+
+If your system is running without interrupts active, the application
+will terminate immediately.
+
+All slots have vectors even if the corresponding interrupt is not
+doing anything.  In this case, the vector is pointing to the "bad
+interrupt" handler.
+
+If you hook a vector that is not receiving any interrupts, the
+down-counter will not do anything.
+
+
+** Etymology* *
+
+The `INTTEST` command is an original product and the source code is
+provided in the RomWBW distribution.

-
-This directory ("Binary") is part of the RomWBW System Software 
-distribution archive.  Refer to the ReadMe.txt file in this 
-directory for more information on the overall contents of the 
-directory.
-
-RomWBW includes a set of disk images that are ready to copy onto
-a floppy or hard/CF/SD disk.  You can use your modern computer
-(Windows/Linux/Mac) to copy the disk image file onto your disk
-media.  The disk media will then be ready to use in your RomWBW
-System.
-
-A description of the disk images is provided later in this file.
-For more information on the creatioin of these images including
-instructions for customizing them or creating your own, refer to
-the ReadMe.txt file in the Source\Images directory.
-
-Installing Images
------------------
-
-The following instructions apply to Windows computers.  Alternatively,
-you can use the "dd" command on Linux or Mac.
-
-First of all, a MAJOR WARNING!!!!  The tools described below are 
-quite capable of obliterating your running Windows system drive.  Use 
-with extreme caution and make sure you have backups.
-
-To install a floppy image on floppy media, you can use the tool 
-called RaWriteWin.  This tool is included in the Tools directory of 
-the distribution. This tool will write your floppy image (fd_xxx.img) 
-to a floppy disk using a raw block transfer.  The tool is GUI based 
-and it's operation is self explanatory.
-
-To install a hard disk image on a CF card or SD card, you must have 
-the appropriate media card slot on your computer. If you do, you can 
-use the tool called Win32DiskImager. This tool is also included in 
-the Tools directory of the distribution.  It will write your 
-hard disk image (hd_xxx.img) to the designated media card.  This tool 
-is also GUI based and self explanatory.
-
-The use of the SIMH emulator is outside of the scope of this document.  
-However, if you use SIMH, you will find that you can attach the hard 
-disk images to the emulator with lines such as the following in your 
-SIMH configuration file:
-
-  | attach hdsk0 hd_cpm22.img
-  | set hdsk0 format=HDSK
-  | set hdsk0 geom=T:2048/N:256/S:512
-  | set hdsk0 wrtenb
-  
-Making Disk Images Bootable
----------------------------
-
-The Operating System disk images below are ready to boot by the
-RomWBW Boot Loader.  However, if you update your RomWBW ROM, then
-you should also update the system tracks of your bootable disk
-images.  You would use SYSCOPY to do this.  SYSCOPY can also be
-used to make a disk bootable if it is not already bootable.
-
-You would use a command like the following to make drive C bootable:
-
-  | B>SYSCOPY C:=CPM.SYS
-
-The system file to use depends on the operating system you are trying
-to boot from the slice you are initializing with SYSCOPY:
-
-  CP/M 2.2 - cpm.sys
-  ZSDOS 1.1 - zsys.sys
-  CP/M 3 - cpmldr.sys
-  ZPM3 - cpmldr.sys
-  
-Slices
-------
-
-A RomWBW CP/M filesystem is fixed at 8MB.  This is because it is the 
-largest size filesystem supported by all common CP/M variants. Since 
-all modern hard disks (including SD Cards and CF Cards) are much 
-larger than 8MB, RomWBW supports the concept of "slices".  This 
-simply means that you can concatenate multiple CP/M filesystems (up 
-to 256 of them) on a single physical hard disk and RomWBW will allow 
-you to assign drive letters to them and treat them as multiple 
-independent CP/M drives.
-
-With the exception of the hd_combo image, each of the disk images
-includes a single CP/M file system (i.e., a single slice).  However,
-you can easily create a multi-slice disk image by merely concatenating 
-multiple images together.  For example, if you wanted to create a 2 
-slice disk image that has ZSDOS in the first slice and Wordstar in 
-the second slice, you could use the following command from a Windows 
-command prompt:
-
-  | C:\RomWBW\Binary>copy /b hd_zsdos.img + hd_ws.img hd_multi.img
-
-You can now write hd_multi.img onto your SD or CF Card and you will 
-have ZSDOS in the first slice and Wordstar in the second slice.
-
-The hd_combo disk image is an example of this.  It contains several
-slices in one image file.  The contents of this special disk image
-are described below.
-
-The concept of slices applies ONLY to hard disks.  Floppy disks are 
-not large enough to support multiple slices.
-
-Disk Image Contents
--------------------
-
-What follows is a brief description of the contents of the
-disk images automatically provided in the RomWBW distribution.
-Note that all of the OS images include the RomWBW custom
-support apps.
-
-cpm22 - DRI CP/M 2.2 (Bootable Floppy and Hard Disk)
-
-  Standard DRI CP/M 2.2 distribution files along with a few commonly
-  used utilities.
-
-zsdos - ZCPR1 + ZSDOS 1.1 (Bootable Floppy and Hard Disk)
-
-  Contains ZCPR1 and ZSDOS 1.1.  This is roughly equivalent to the
-  ROM boot contents, but provides a full set of the applications
-  and related files that would not all fit on the ROM drive.
-
-nzcom - NZCOM (Bootable Floppy and Hard Disk)
-
-  Standard NZCOM distribution.  Note that you will need to run the
-  NZCOM setup before this will run properly.  You will need
-  to refer to the NZCOM documentation.  
-
-cpm3 - DRI CP/M3 (Bootable Floppy and Hard Disk)
-
-  Standard DRI CP/M 3 adaptation for RomWBW that is ready to run.
-  It can be started by running CPMLDR.
-
-zpm3 - ZPM3 (Bootable Floppy and Hard Disk)
-
-  Simeon Cran's ZCPR 3 compatible OS for CP/M 3 adapted for RomWBW and 
-  ready to run.  It can be started by running CPMLDR (which seems 
-  wrong, but ZPMLDR is somewhat broken).
-
-ws4 - WordStar 4 (Floppy and Hard Disk)
-
-  Micropro Wordstar 4 full distribution.  This image is not bootable
-  and is intended to be added as an additional slice to an OS image.
-
-bp - BPBIOS (Hard Disk only)
-
-  Adaptation of BPBIOS for RomWBW.  This is NOT complete and NOT
-  useable in it's current state.
-
-combo - Multi-Boot Combination (Bootable Hard Disk)
-
-  A pre-created combo image that contains the following slices.  The
-  slices are identical to the individual images listed above.
-
-    Slice 0: cpm22 (bootable)
-    Slice 1: zsdos (bootable)
-    Slice 2: nzcom (bootable)
-    Slice 3: cpm3 (bootable)
-    Slice 4: zpm3 (bootable)
-    Slice 5: ws4 (not bootable)

-***********************************************************************
-
-This directory ("Binary") is part of the RomWBW System Software
-distribution archive.  Refer to the ReadMe.txt file in this
-directory for more information on the overall contents of the
-directory.
-
-When distributed, RomWBW contains a set of pre-built ROM images that
-are ready to program onto the EEPROM of any of the Z80/Z180 based
-RetroBrew Computers CPU boards.  Additionally, any custom built ROM
-images will be placed in this directory.
-
-All of the pre-built ROM images are 512KB.  This size is compatible
-with all of the Z80/Z180 systems.  Some systems can accept different
-size ROM images.  Creating alternative sizes requires a custom ROM
-build (see ReadMe.txt in the Source directory).
-
-It is critical that the right ROM Imgae be selected for the target
-platform being used.  The table below indicates the correct ROM
-image to use for each platform:
-
-	SBC V1/V2	SBC_std.rom
-	SBC SimH	SBC_simh.rom
-	Zeta V1		ZETA_std.rom
-	Zeta V2		ZETA2_std.rom
-	N8		N8_std.rom
-	Mark IV		MK4_std.rom
-	RC2014 w/ Z80	RCZ80_std.rom
-	RC2014 w/ Z180	RCZ180_nat.rom	(native Z180 memory addressing)
-	RC2014 w/ Z180	RCZ180_ext.rom	(external 512K RAM/ROM module)
-	SC-series	SC126, SC130
-	Easy Z80	EZZ180_std.rom
-	Dyno		DYNO_std.rom
-
-You will find there is one additional ROM image called
-"UNA_std.rom". This ROM image is an UNA-based RomWBW ROM image.  As
-such, this ROM image can be used on any Z80/Z180 platform supported
-by John Coffman's UNA BIOS.  Refer to RetroBrew Computers Wiki for
-more information on UNA hardware support.
-
-For each of the ROM Images (".rom"), there are corresponding files
-with the extensions of ".com" and ".img".  The .com variant can be
-copied to a functional RomWBW-based system and executed like a
-normal application under CP/M or Z-System. This will load the new
-ROM on-the-fly.  It is an excellent way to test a ROM Image before
-actually burning it.  Similarly, the .img files can be loaded using
-the UNA FAT loader for testing.
-
-WARNING: In a few cases the .com file is too big to load.  If you get
-a message like "Full" or "BAD LOAD" when trying to load one of the
-.com files, it is too big.  In these cases, you will not be able to
-test the ROM prior to programming it.
-
-All of the standard ROM Images are configured for:
- - 512KB ROM Disk
- - 512KB RAM Disk
- - 38.4Kbps baud serial console (*)
- - Auto-discovery of all serial ports
-
-* RC2014 and Stephen Cousins' kits run at 115,200Kbps baud
-
-All hard disk type devices (IDE, PPIDE, CF Card, SD Card) will be
-automatically assigned two drive letters per device.  The drive
-letters will refer to the first 2 slices of the device. The ASSIGN
-command can be used to display and reassign drives to disk devices
-and slices as desired.
-
-Standard ROM Image Notes
-------------------------
-
-The standard ROM images will detect and install support for certain
-devices and peripherals that are on-board or frequently used with
-each platform as documented below.  If the device or peripheral is
-not detected at boot, the ROM will simply bypass support
-appropriately.
-
-SBC (SBC_std.rom):
- - CPU speed is detected at startup
- - Console on onboard UART serial port at 38400 baud
- - Includes support for PPIDE/CF Card(s) connected to on-board
-   parallel port.
- - Includes support for CVDU and VGA3 boards.  If detected at
-   startup, support for video and keyboard is installed
-   including VT-100/ANSI terminal emulation.
- - Auto-detects PropIO or PropIO V2 and installs associated
-   video, keyboard and SD Card support if present.
- - If PropIO, PropIO V2, CVDU, or VGA hardware is detected,
-   initial console output is determined by JP2.  If JP2 is
-   shorted, console will go to on-board serial port, if JP2
-   is open, console will go to the detected video and keyboard
-   ports.
- - SBC V1 has a known race condition in the bank switching
-   circuit which is likely to cause system instability.  SBC
-   V2 does not have this issue.
-
-SBC (SBC_simh.rom):

-   on-board serial port, if JP1 is open, console will go to
-   ParPortProp video and keyboard ports.
-
-ZETA2 (ZETA2_std.rom):
- - CPU speed is detected at startup
- - Console on onboard UART serial port at 38400 baud

+
+## Coding Style
+
+Due to the nature of the project, you will find a variety of coding styles.  When making changes to existing code, please try to be consistent with the existing coding style.  You may not like the current style, but no one likes mixed styles
+in one file/module.
+
+Be careful with white space.  RomWBW is primarily assembly langauge code.  The use of tab stops at every 8 characters is pretty standard for assembler.  If you use something else, then your code will look odd when viewed by others.
+
+In most cases, the use of `<cr><lf>` line endings is preferred.  This is standard for the operating systems of the era that RomWBW provides.  Also note that CP/M text files should end with a ctrl-Z (0x1A).  This is not magically added by the
+tools that generate the disk images.

+A Personal Note
+===============
+
+Somehow, I've managed to get by for the last 14 years using just ZCPR.
+But like some of you, I have fiddled with the standard ZCPR and
+modified it to suit my tastes.  As I added new commands or enriched old
+ones, I've always remained compatible with existing programs, all the
+BDOS replacements, and, most important of all, stayed within the 800H
+space allocation of the original Digital Research CCP.  Here are the
+fruits of my labors, I hope you enjoy this CCP replacement as much as I
+do.
+
+        Don Kirkpatrick
+        17595 S.W. Pheasant Lane
+        Beaverton, Oregon 97006
+        <Donald.C.Kirkpatrick@tek.com>
+
+
+Introduction
+============
+
+This console replacement is designed to run under CP/M 2.2 or any of
+the 2.2 BDOS replacements.  It requires a Z80 or better.  If you are
+running DRI's CCP or older versions of ZCPR1, this program is a
+significant improvement.  If you are running ZCPR3, CP/M 3.0, CP/M
+Plus, or MP/M, this will probably be a disappointment.
+
+If you are familiar with ZCPR3, you will recognize many of the
+enhancements here: comments on a command line, search path for the .com
+file, drive/user change with simple du:, CLEVEL3 command processing,
+proper SUBMIT file facility, and so on.  Nothing has been removed from
+DRI's CCP, only new features added.  AND IT ALL STILL FITS IN THE
+ORIGINAL 800H, THE SAME SPACE AS THE DIGITAL RESEARCH FIVE COMMAND
+CCP.
+
+Many of the standard commands have been enhanced.  For example, TYPE
+and LIST now have options to turn on or off page breaks.  Moreover, the
+console check for abort has been improved.
+
+Two commands have been added for use in submit files - SAK and BELL.
+These commands allow you to pause or ring the bell during submit file
+execution.
+
+Before you install this version of ZCPR onto your boot disks, try it by
+running it as a .com file.  Just edit the few customizing options and
+assemble the source.  After you decide it really is better, load it
+onto your boot track and make it your standard.  Complete instructions
+are located at the end of this document.
+
+The complete built-in command list is:
+
+    DIR - directory command enhanced to list optionally all user areas
+    REN - standard rename command
+    USER- move to new user number area on same drive
+    SAVE- save specified number of TPA pages or records in a file
+    TYPE- display a file on the console with optional page break pauses
+    LIST- print command plus optional form feed insertion
+    PAGE- send form feed to list device
+    ERA - standard file erase command
+    ERAQ- file erase with confirmation query at each file
+    DFU - set default user number for .com search path
+    BELL- send a bell character to the console
+    SAK - pause until a key is struck on the console (Strike Any Key)
+    SCL - toggle multiple commands per line (Single Command on a Line)
+    GET - load a file into the TPA at any specified location
+    JUMP- process command tail and execute program at specified address
+    GO  - process command tail and execute program loaded at 100H
+    PEEK- display hexadecimal byte string starting with specified address
+    POKE- load hexadecimal byte string starting with specified address
+    BOOT- execute BIOS cold boot routine
+
+
+Filename Processing
+===================
+
+The standard ZCPR3 du: drive/user file specification has been
+implemented.  Any filename can be in the du:fn.ft form.  For example:
+
+       A>era c4:junk*.*
+
+erases files on the C drive, user area 4 without leaving drive A user
+0.  When a user number is found in a filename, that user number is
+placed in S1 of the default FCB.  Bit 7 of S1 is set to inform the
+program using the FCB a user number was found.
+
+The * in an ambiguous file name has been improved.  Now a trailing *
+causes the remainder of the ambiguous name to be filled with '?', not
+just the fn field.  For example:
+
+       A>era c4:junk*
+
+is the same as the example above.  Previously, junk* was defined as
+'junk????.   '.  If you need the ft field blank, type 'junk*.'.  The
+question mark still works as a single character wild card.
+
+
+Command Line Processing
+=======================
+
+The  current user number is included as part of the command prompt for
+all non-zero user numbers.  The prompt is of the form du>, for example
+A2> or B10>.  If the SUPRES equate is true, the user number is
+suppressed for user 0 only.
+
+Multiple commands are typed on a single line separated by a command
+separator character.  Occasionally, you need to type the separator
+character in a command tail.  The SCL command toggles the multiple
+command enable.  The CMDCHR equate determines the command separator
+character.  A ';' has been chosen as the separator character in this
+distribution version.
+
+Comments are allowed on a command line.  When the comment separator
+character is encountered as the first character of a command, the
+remainder of the line is ignored.  The COMCHR equate determines the
+comment separator character.  A ';' has been chosen as the separator
+character in this distribution version.  Here is an example containing
+comments and multiple commands on a single line:
+
+   A>get 100 junk;peek 100;;this is a comment.
+   A>;this is also a comment.
+
+There exists a built-in search path for transient commands.  First, the
+current drive/user is searched.  Next, the current drive/default user
+is searched.  Last, drive A/default user is searched.  The DEFUSR
+equate determines the default user number, currently set to user 0 in
+this distribution version.  The default user is temporarily changed
+with the DFU command.  If a drive is specified in the transient
+command, the current and default user areas on the specified drive are
+searched.  If a user number is specified, that user area on the current
+and default drive are searched.  If both the drive and user number are
+specified, no search is performed.  The same drive/user area is never
+searched twice.
+
+Transient commands are always "called."  If a program terminates via a
+return rather than a warm boot, subsequent multiple commands on the
+command line are executed.  Any program exiting by a warm boot reloads
+ZCPR and the subsequent commands lost.
+
+A default command can be placed in the command buffer and control
+passed to ZCPR for processing.  The only thing required, besides
+placing the command in the buffer and jumping to CPRLOC, is to
+initialize the command character counter at the start of the buffer.
+The procedure is compatible with the original DRI CCP default command
+processing.  If ZCPR is entered at CPRLOC+3 jump, default command
+processing is suppressed.  Either way, register C must contain a valid
+drive/user, just like the original CCP.
+
+
+Submit File Processing
+======================
+
+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.  It
+ALWAYS looked for the $$$.SUB file on drive A and the submit program
+would place it on the current default drive.  When the you were logged
+onto drive B and you issued a submit command, the $$$.SUB was placed on
+drive B and not executed.
+
+After much debate it was decided to have ZCPR perform the same type of
+function as CCP (look for the $$$.SUB file on drive A), but the problem
+with SUBMIT.COM still exists.  Hence, RGF designed SuperSUB and RLC
+took his SuperSUB and designed SUB from it; both programs are set up to
+allow the selection at assembly time of creating the $$$.SUB on the
+default drive or on drive A.  If you don't have one of these newer
+submit programs, a procedure for patching the standard SUBMIT.COM has
+been included at the end.
+
+The fixed drive choice permits a submit file to contain a series of
+commands exactly as they would be entered from a CP/M console.  This
+permits things like:
+
+    A>dir
+    A>b:
+    B>dir
+
+to be executed, even though the currently default drive is changed
+during execution. If the $$$.SUB file were present on the default
+drive, the above series of commands would not work.  ZCPR would be
+looking for $$$.SUB on the default drive, and switching default drives
+without moving the $$$.SUB file would cause processing to abort.  Note
+that the same problem occurs if the user number of the $$$.SUB file is
+not predefined. ZCPR assumes that the $$$.SUB file is located on user 0
+of drive A.
+
+The trick of using the $ flag returned by the BDOS disk reset is used
+to speed the search for a $*.* file on drive A. This trick will not
+work if the $$$.SUB file were located on another drive.
+
+The '>' prompt character is replaced by a special character while a
+submit file is in execution.  The SPRMPT equate defines this special
+character, currently set to '$' in this distribution version.
+
+
+Command Syntax
+==============
+
+Multiple commands can be placed on one line.  If the comment character
+is encountered where a command should start, the rest of the line is
+ignored.  Any command can be renamed by editing the command table.
+Command names can be up to eight characters long and are terminated by
+bit 7 high.  If there is a conflict between an internal ZCPR command
+and a transient program of the same name, the internal command is
+executed.  Type the command with the du: included if the external
+transient command is the one desired.  Here is a complete alphabetized
+list of all the resident commands with their syntax:
+
+=============================================================================
+
+Command:  BELL
+
+Function: To ring terminal bell.
+
+Forms:    BELL
+
+Options:  None.
+
+Uses:     This command is designed to be placed in a submit file to
+          ring the bell to indicate significant checkpoints.
+
+=============================================================================
+
+Command:  BOOT
+
+Function: To execute BIOS cold boot routine.
+
+Forms:    BOOT
+
+Options:  REBOOT equate controls the inclusion/exclusion of this command.
+
+Uses:     Reboots the system without pushing the reset button.  The
+          cold boot entry point in the BIOS must be supported for this
+          command to work.
+
+=============================================================================
+
+Command:  DFU
+
+Function: To set the Default User Number for transient commands.
+
+Forms:    DFU <usrnum>

+
+          NUMBASE equate defines the character that specifies a
+          hexadecimal number.  The distribution version is set to 'H'.
+
+Uses:     The default user area is searched after a transient command
+	  cannot be found in the current user area.  If the transient
+	  command still has not been found, the default user on the
+	  default drive is searched last.  The new default user number
+	  is in decimal, but hexadecimal numbers are entered by
+	  appending an 'H'.  The next warm boot will restore the
+	  original default user number.
+
+=============================================================================
+
+Command:  DIR
+
+Function: To display a directory listing of the files on a drive.
+
+Forms:    DIR <afn>       Display the DIR files

+          change the horizontal width of a directory display.
+
+          FENCE equate specifies the character separator between the
+          directory columns.
+
+          USRDLM equate specifies the character between the user number
+          and the filename.
+
+          USRFLG, SYSFLG, and SOFLG equates specify the command line
+          tail character that control the display of system and
+          non-system files.
+
+Uses:     Displays a directory listing of files in specific drive/user
+          area.
+
+=============================================================================
+
+Command:  ERA
+
+Function: To erase files.
+
+Forms:    ERA <afn>
+
+Options:  None.
+
+Uses:     Deletes files.  Names of erased files are displayed.
+
+=============================================================================
+
+Command:  ERAQ
+
+Function: To erase files with individual query.
+
+Forms:    ERAQ <afn>
+          <afn>? y          File erased
+          <afn>? <CR>       File not erased
+
+Options:  None.
+
+Uses:     Deletes a subset of a set of ambiguously specified files.
+          Any answer other than 'Y' (either case) will cause the file
+          to be skipped and not erased.
+
+=============================================================================
+
+Command:  GET
+
+Function: To load the specified file from disk to the specified address.
+
+Forms:    GET <hexadr> <ufn>
+
+Options:  None.
+
+Uses:     Loads a file into the TPA for patching purposes.  This command
+          searches for the specified file along the same search path as
+          the transient command loader.
+
+
+=============================================================================
+
+Command:  GO
+
+Function: To call the program in the TPA without loading from disk.
+
+Forms:    GO <command tail>
+
+Options:  None.
+
+Uses:     Most useful to rerun a program already loaded into the TPA.
+          Saves time and wear on disk drives.  The command tail is
+          entered exactly as it would appear if GO were replaced by the
+          program name.  Same as JUMP 100H, but more convenient,
+          especially when used with parameters for programs like STAT.
+
+=============================================================================
+
+Command:  JUMP
+
+Function: To call the program at a specified address.
+
+Forms:    JUMP <hexadr> <command tail>
+
+Options:  None.
+
+Uses:     Executes code not located at 100H.  For example, JUMP 0
+          warm boots.  The code must already reside at the specified
+          address.
+
+=============================================================================
+
+Command:  LIST
+
+Function: To print specified file on list device.
+-
+Forms:    LIST <ufn>      Print file
+          LIST <ufn> P    Print file without default paging

+Options:  NLINEP equate determines the number of lines per page.
+
+          FFKILL equate controls the suppression of form feeds before
+          printable text.
+
+          PGDFLG equate determines the command line tail character that
+          toggles the default form feed insertion every NLINEP lines.
+
+          NOSTAT equate controls the use of the BIOS list status call.
+
+Uses:     Prints files with/without pagination on LST: device.  A
+          listing is aborted by a console ^C.  Any submit file in
+          process is terminated and control is returned gracefully to
+          the console prompt.
+
+=============================================================================
+
+Command:  PAGE
+
+Function: To eject a page on list device via a form feed.
+
+Forms:    PAGE
+
+Options:  NOSTAT equate controls the use of the BIOS list status call.
+
+Uses:     Sends a form feed to the LST: device.  The page eject can
+	  be aborted by a console ^C if the system hangs because the
+	  printer is not ready.  If aborted, any submit file in process
+	  is terminated and control is returned gracefully to the
+	  console prompt.
+
+=============================================================================
+
+Command:  PEEK
+
+Function: To display hex values beginning at a specified address.
+
+Forms:    PEEK <hexadr> [<hexcnt>]
+
+Options:  None.
+
+Uses:     Displays hexadecimal values anywhere in the entire address
+          space.  The maximum value for <hexcnt> is 0FFH, but the
+          default <hexcnt> is 256.
+
+=============================================================================
+
+Command:  POKE
+
+Function: To poke a string of hex values into a set of consecutive
+          addresses.
+
+Forms:    POKE <hexadr> <hexval> [...<hexval>]
+
+Options:  None.
+
+Uses:     Modifies values anywhere in the entire address space.  Each
+          <hexval> represents one byte and is separated from the next
+          by a space.  The number of <hexval> are limited only by the
+          size of the command line buffer. The address is incremented
+          for each <hexval>.  Excellent for hand patching code.
+
+=============================================================================
+
+Command:  REN
+
+Function: To change the name of an existing file.
+
+Forms:    REN <newufn>=<oldufn>
+          REN <newufn>=<oldufn>     Existing <newufn>
+          Delete? y                 File deleted
+
+Options:  None.
+
+Uses:     Changes the names of files.  Any du: on <oldufn> is ignored;
+          the optional du: is on <newufn>.  If there already exists a
+          <newufn>, the console is queried for conformation.  Any
+          response except 'Y' (either case) aborts the command, kills
+          any submit file in process, and returns gracefully to the
+          command prompt.
+
+=============================================================================
+
+Command:  SAK
+
+Function: To pause until a key is struck.
+
+Forms:    SAK
+          ? <any key>
+
+Options:  None.
+
+Uses:     Pauses a submit file until a keystroke is entered.  Any
+	  character other than a ^C will resume execution.  A ^C kills
+	  the submit file, any commands remaining on the command the
+	  line are ignored, and control returns gracefully to the
+	  prompt.
+
+=============================================================================
+
+Command:  SAVE
+
+Function: To save the contents of TPA onto disk as a file.
+
+Forms:    SAVE <Number of Pages> <ufn>
+          SAVE <Number of Records> <ufn> R
+
+Options:  RECFLG equate determines the command tail character that
+          specifies records rather than pages.
+
+          NUMBASE equate defines the character that specifies a
+          hexadecimal number.  The distribution version is set to 'H'.
+
+Uses:     Saves the TPA to a file.  Records are 128 bytes long, pages
+	  are 256 bytes long.  Number of pages or records is in
+	  decimal, but a hexadecimal number is entered by appending an
+	  'H'.  Saved area begins at 100H.
+
+=============================================================================
+
+Command:  SCL
+
+Function: To force ZCPR to parse only a single command per line.
+
+Forms:    SCL
+
+Options:  MULTPL equate determines the inclusion/exclusion of this
+          command and whether or not multiple commands are allowed.
+
+          CMDCHR equate determines the character separating multiple
+          commands.
+
+Uses:     Some transient commands require the command separator in the
+          command tail.  This command turns off multiple command
+          parsing so the entire command tail is sent to the transient
+          program.  Multiple command format is reset at the next warm
+          boot. SCL toggles.
+
+=============================================================================
+
+Command:  TYPE
+
+Function: To display specified file on console.
+
+Forms:    TYPE <ufn>      Display file
+          TYPE <ufn> P    Display file without default paging
+
+Options:  NLINES equate determines the number of lines per screen.
+
+          FFKILL equate controls the suppression of form feeds before
+          printable text.
+
+          PGDFLG equate determines the command line tail character that
+          toggles the default form feed insertion every NLINEP lines.
+
+Uses:     Displays files with/without pagination on CON: device.  A
+          display is aborted by a console ^C.  If aborted, any submit
+          file in process terminates and control returns gracefully to
+          the console prompt.  When page breaks are enabled, any
+          console character except ^C will display the next page of
+          text.
+
+=============================================================================
+
+Command:  USER
+
+Function: To change current user number.
+
+Forms:    USER <usrnum>
+
+Options:  SUPRES equate controls the display of the user number in the
+          prompt when the user number is zero.
+
+          MAXUSR equate controls the maximum allowable user number.
+
+          NUMBASE equate defines the character that specifies a
+          hexadecimal number.  The distribution version is set to 'H'.
+
+Uses:     This command changes the current user number.  The new user
+          number is in decimal, but a hexadecimal number is entered by
+          appending an 'H'.  This command has been retained for
+          compatibility purposes only.  It is far easier to change
+          disk/user by typing du:.

+Error Messages
+==============
+
+If any error is encountered as a command line is being parsed, a
+message will be printed and, for serious errors, the remainder of the
+line is ignored.  Below is a complete list of all ZCPR error messages.
+Any error message encountered that is not on this list came from some
+program other than ZCPR.
+
+"?"
+
+   An error was detected in the command.  The an item on the command
+   line was not what was expected.  The command line is echoed up to
+   the position where the error was detected, as close as can be
+   determined, and the "?" printed.  Any commands remaining on the
+   command the line are ignored and any $$$.SUB file erased.
+
+"Full"
+
+   If ZCPR was attempting to load a transient program, one of two
+   things has gone wrong: either the program is so large that it won't
+   fit into the TPA or a read error was returned from the BDOS.  If
+   ZCPR was attempting to save a file, the BDOS write call returned
+   failure. Either the disk or the directory is full.  Any commands
+   remaining on the command line are ignored and any $$$.SUB file
+   erased.
+
+"No File"
+
+   No file could be found matching the filename specified in the
+   command.  This message is also be printed if the BDOS read command
+   returns failure.  If ZCPR was looking for a transient command, any
+   commands remaining on the command line are ignored and any $$$.SUB
+   file erased.
+
+"Name Error"
+
+   The specified filename has a user number larger than the allowable
+   maximum or an ambiguous filename was entered where only an
+   unambiguous filename is permitted.  Any commands remaining on the
+   command line are ignored and any $$$.SUB file erased.
+
+"Delete?"
+
+   Not really an error, but there already exists a file with the same
+   name as the requested new name in the REN command.  Any response
+   except 'Y' (either case) aborts the command, any commands remaining
+   on the command line are ignored, and any $$$.SUB file erased.
+
+"All?"
+
+   Not really an error, but a check to verify that all files on the
+   drive/user area are to be erased.  Any response except 'Y' (either
+   case) aborts the command and any commands remaining on the command
+   line are ignored.
+
+
+Installation Instructions
+=========================
+
+1) The first task is to determine the location of your BDOS because you
+   MUST set the P2DOS equate to this value.  If you do not know the
+   location of your BDOS, use ZCPRDEMO to find it.  If you do not
+   already have ZCPRDEMO.COM, assemble ZCPR with the TEST equate true
+   to make it.  A bootstrap loader will be included and you can run the
+   .com file.  This program assembles without errors using Microsoft's
+   M80/L80:
+
+   A>m80 =zcpr
+   A>l80 zcpr,zcprdemo/n/e
+
+   Other assemblers can be used, but ZCPR.MAC will probably require
+   editing to convert it to a form compatible.  The major decision in
+   converting is to determine how the .PHASE pseudo is to be handled.
+   Probably the best solution to the .PHASE is to generate a .hex
+   file and load it with an offset using DDT/SID/ZSID.  Consult the
+   "r" command in the DDT/SID/ZSID manaul.
+
+   Run ZCPRDEMO and peek at low memory:
+
+   A>zcprdemo
+   A<peek 0 10
+   0000 C3 03 F2 00 00 C3 06 E4 00 00 00 00 00 00 00 00
+   A<^C
+
+   Notice the prompt character has changed from a '>' to a '<'.  This
+   tells you the special debug version of ZCPR is running.  See the
+   debug section at the end for details.  Address 0 contains a jump 3
+   beyond the start of the BIOS and address 5 contains a jump 6 beyond
+   the start of the BDOS.
+
+   Be careful if you attempt to execute a transient program from
+   ZCPRDEMO.  Some transient programs, like NSWP, return rather than
+   warm boot when done. These programs don't know that ZCPRDEMO is at
+   address 8000H rather than just under the BDOS.  If they overwrite
+   ZCPRDEMO, then the return is to random code. Of course, this is not
+   a problem when ZCPR is installed just under the BDOS.
+
+2) You MUST edit the code to place your BDOS/P2DOS/Z80DOS/ZRDOS start
+   address in the P2DOS equate.  Set COMLD true (and TEST false if you
+   set it true in step 1 above) and make ZCPR.COM.  A bootstrap loader
+   will be included.
+
+   Assuming you successfully assemble it, just type "zcpr" to run it.
+   However, every time there is a warm boot, it will be  replaced by
+   the boot track CCP.  If you like what you see, place a copy on the
+   boot track to make it available all the time.
+
+3) Reassemble, this time with COMLD false to make ZCPRNBLD.COM (ZCPR
+   No Boot LoaDer).  
+
+4) Run SYSGEN to load a copy of the boot track into memory.
+
+   B>; Sample terminal session for integrating ZCPR
+   B>sysgen
+   SYSGEN VER 2.2
+   SOURCE DRIVE NAME (OR RETURN TO SKIP)a
+   SOURCE ON A, THEN TYPE RETURN  <cr>
+   FUNCTION COMPLETE
+   DESTINATION DRIVE NAME (OR RETURN TO REBOOT)  <cr>
+
+
+5) Run SAVE to save a track image to a file (eg: SAVE 32 BOOTFILE).
+   The number on the save command depends on the size of your boot
+   track loader; it can be as small as 31 and as large as 44.  If you
+   have extra disk space or are not sure, play it safe and use 44.
+
+   B>save 44 cpm56.com      <-- We now have a SYSGEN image of CP/M
+
+6) Find the location of the stock CCP by peeking at the boot file. It
+   is normally located at address 980H in the file. Using ZCPR:
+
+   B>zcpr                   <-- Reload zcpr.com version
+   B>get 100 cpm56.com
+
+   and search for the start of the console processor:
+
+   B>peek 980
+   0980 C3 xx xx C3 xx xx 7F 00 43 4F 50 59 52 49 47 48
+   0990 54 20 ...
+
+   If you don't find the start of the CCP at 980H, don't be
+   discouraged. It is there, but at a higher address.  Keep looking.
+
+7) When you find the location of the CCP, patch it with the new ZCPR
+   image.
+
+   B>get 980 zcprnbld.com
+
+8) Place the new file onto the boot track of a test disk, not your
+   original, using SYSGEN, and try it out.
+
+   B>sysgen
+   SYSGEN VER 2.2
+   SOURCE DRIVE NAME (OR RETURN TO SKIP) <cr>      <-- Use memory image
+   DESTINATION DRIVE NAME (OR RETURN TO REBOOT)b   <-- Load onto drive B
+   DESTINATION ON B, THEN TYPE RETURN <cr>
+   FUNCTION COMPLETE
+   DESTINATION DRIVE NAME (OR RETURN TO REBOOT) <cr>
+
+   You should now have a ZCPR system boot disk.  Notice you did all
+   your work on drive B so you wouldn't destroy the original.
+
+
+
+This may seem like a great number of steps, but each is only a single
+CP/M command line, total time is only 5 minutes or so after you get
+ZCPR to run as a .com file.
+
+
+Debugging ZCPR
+==============
+
+Special provisions have been make to ease the debugging of ZCPR.
+Setting the TEST equate true causes the assembler to build a version of
+ZCPR that executes in the TPA.  This allows the use of a debugger like
+DDT, ZSID, or Z8E to load and monitor execution.  To identify the debug
+version, the prompt character is changed from '>' to '<' when it runs.
+
+CPRLOC for the test version is 8000H.  A bootstrap loader is included
+at the beginning to move the image to this address.  Do not try to set
+a breakpoint until after the loader has moved ZCPR.  The easiest way to
+accomplish this is to single-step through the loader and then set your
+breakpoints.  Change the execution address to something lower if 8000H
+does not leave enough space for the debugger.
+
+A small amount of code is also added at the end of the debug version to
+compute the BIOS list status and cold boot entry points at run time.
+This permits the demo version to execute properly without setting the
+BDOS location equate.
+
+Patching SUBMIT.COM
+===================
+
+SUBMIT.COM is patched to run with ZCPR by the following procedure.
+This is recommended if the user does not have one of the newer public
+domain versions of submit.  This patch simply makes SUBMIT.COM always
+place the $$$.SUB file on drive A.  Illustrative terminal session
+follows:
+
+  A>get 100 submit.com;peek 5bb 2
+  05BB 00 24              <-- Patch is at 5BB Hex
+  A>poke 5bb 1            <-- Change 0 (default drive) to 1 (drive A)
+  A>peek 5b0 20           <-- Let's check just to make sure
+  05B0 00 00 00 00 00 00 30 30 31 20 24 01 24 24 24 20
+  05C0 20 20 20 20 53 55 42 00 00 00 1A 1A 1A 1A 1A 1A
+  A>save 5 newsubmt.com   <-- Save new SUBMIT.COM file
+
+Pretty simple, huh?

-                          http://sowerbutts.com/8bit/
-
-= Warning =
-
-FLASH4 has been tested and confirmed working on:
- * N8VEM SBCv2
- * N8VEM N8-2312
- * N8VEM Mark IV SBC
- * DX-Designs P112
- * ZETA SBC v2
-
-However it remains somewhat experimental. If it works for you, please let me
-know. If it breaks please also let me know so I can fix it!
-
-
-= Introduction =
-
-FLASH4 is a CP/M program which can read, write and verify Flash ROM contents to
-or from an image file stored on a CP/M filesystem. It is intended for in-system
-programming of Flash ROM chips on Z80 and Z180 systems.
-
-FLASH4 aims to support a range of Flash ROM chips. Ideally I would like to
-support all Flash ROM chips that are in use in Z80/Z180 N8VEM machines. If
-FLASH4 does not support your chip please let me know and I will try to add
-support.
-
-When writing to the Flash ROM chip, FLASH4 will only reprogram the sectors
-whose contents have changed. This helps to reduce wear on the flash memory,
-makes the reprogram operation faster, and reduces the risk of leaving the
-system unbootable if power fails during a reprogramming operation. FLASH4
-always performs a full verify operation after writing to the chip to confirm
-that the correct data has been loaded.
-
-FLASH4 is reasonably fast. Reprogramming and verifying every sector on a 512KB
-SST 39F040 chip takes 21 seconds on my Mark IV SBC, versus 45 seconds to
-perform the same task using a USB MiniPro TL866 EEPROM programmer under Linux
-on my PC. If only a subset of sectors require reprogramming FLASH4 will be
-even faster.
-
-FLASH4 works with binary ROM image files, it does not support Intel Hex format
-files. Hex files can be easily converted to or from binaries using "hex2bin" or
-the "srec_cat" program from SRecord:
-
-  $ srec_cat image.hex -intel -fill 0xFF 0 0x80000 -output image.bin -binary
-  $ srec_cat image.bin -binary -output image.hex -intel
-
-FLASH4 can use several different methods to access the Flash ROM chip. The best
-available method is determined automatically at run time. Alternatively you may
-provide a command-line option to force the use of a specific method.
-
-The first two methods use bank switching to map sections of the ROM into the
-CPU address space. FLASH4 will detect the presence of RomWBW or UNA BIOS and
-use the bank switching methods they provide. 
-
-On P112 systems the P112 B/P BIOS is detected and P112 bank switching is used.
-
-If no bank switching method can be auto-detected, and the system has a Z180
-CPU, FLASH4 will use the Z180 DMA engine to access the Flash ROM chip. This
-does not require any bank switching but it is slower and will not work on all
-platforms.
-
-Z180 DMA access requires the flash ROM to be linearly mapped into the lower
-region of physical memory, as it is on the Mark IV SBC (for example). The
-N8-2312 has additional memory mapping hardware, consequently Z180 DMA access on
-the N8-2312 is NOT SUPPORTED and if forced will corrupt the contents of RAM;
-use one of the supported bank switching methods instead.
-
-Z180 DMA access requires the Z180 CPU I/O base control register configured to
-locate the internal I/O addresses at 0x40 (ie ICR bits IOA7, IOA6 = 0, 1).
-
-
-= Usage =
-
-The three basic operations are:
-
-  FLASH4 WRITE filename [options]
-
-This will rewrite the flash ROM contents from the named file. The file size
-must exactly match the size of the ROM chip. After the write operation, a
-verify operation will be performed automatically.
-
-  FLASH4 VERIFY filename [options]
-
-This will read out the flash ROM contents and report if it matches the contents
-of the named file. The file size must exactly match the size of the ROM chip.
-
-  FLASH4 READ filename [options]
-
-This will read out the entire flash ROM contents and write it to the named
-file.
-
-If your ROM chip is larger than the image you wish to write, use the "/PARTIAL"
-(or "/P") command line option. To avoid accidentally flashing the wrong file,
-the image file must be an exact multiple of 32KB in length. The portion of the
-ROM not occupied by the image file is left either unmodified or erased.
-
-If you are using an ROM/EPROM/EEPROM chip which cannot be programmed in-system,
-FLASH4 will not be able to recognise it, however the software can still
-usefully READ and VERIFY the chip. Use the "/ROM" command line option to enable
-"READ" or "VERIFY" mode with unrecognised chips. This mode assumes a 512K ROM
-is fitted; smaller ROMs will be treated as a 512K ROM with the data repated
-multiple times -- with a 256K chip the data is repeated twice, four times for a
-128K chip, etc.
-
-One of the following optional command line arguments may be specified at the
-end of the command line to force FLASH4 to use a particular method to access
-the flash ROM chip:
-
-BIOS interfaces:
-  /ROMWBW         For ROMWBW BIOS version 2.6 and later
-  /ROMWBWOLD      For ROMWBW BIOS version 2.5 and earlier
-  /UNABIOS        For UNA BIOS
-
-Direct hardware interfaces:
-  /Z180DMA        For Z180 DMA
-  /P112           For DX-Designs P112
-  /N8VEMSBC       For N8VEM SBC (v1, v2), Zeta (v1) SBC
-
-If no option is specified FLASH4 attempts to determine the best available
-method automatically.
-
-
-= Supported chips and features =
-
-FLASH4 will interrogate your flash ROM chip to identify it automatically.
-FLASH4 assumes that you have a single flash ROM device and it is located at the
-bottom of the physical memory map.
-
-FLASH4 does not support setting or resetting the protection bits on individual
-sectors within Flash ROM devices. If your Flash ROM chip has protected sectors
-you will need to unprotect them by other means before FLASH4 can erase and
-reprogram them.
-
-AT29C series chips employ an optional "software data protection" feature. This
-is supported by FLASH4 and is left activated after programming the chip to
-prevent accidental reprogramming of sectors.
-
-The following chips are supported:
-
-  AT29F010
-  AT29F040
-  M29F010
-  M29F040
-  MX29F040
-  SST 39F010
-  SST 39F020
-  SST 39F040
-  AT29C512
-  AT29C040
-  AT29C010
-  AT29C020
-
-The following chips are supported but have unequal sector sizes; FLASH4 will
-only erase and reprogram the entire chip at once rather than its normal
-sector-by-sector operation:
-
-  AT49F001NT
-  AT49F001N
-  AT49F002N
-  AT49F002NT
-  AT49F040
-
-If you use a flash ROM chip that is not listed above please email me
-(will@sowerbutts.com) and I will try to add support for it.
-
-
-= Compiling =
-
-The software is written in a mix of C and assembler. It builds using the SDCC
-toolchain and the SRecord tools. A Makefile is provided to build the executable
-in Linux and I imagine it can be easily modified to build in Windows.
-
-You may need to adjust the path to the SDCC libraries in the Makefile if your
-sdcc installation is not in /usr/local
-
-
-= License =
-
-FLASH4 is licensed under the The GNU General Public License version 3 (see
-included "LICENSE.txt" file). 
-
-FLASH4 is provided with NO WARRANTY. In no event will the author be liable for
-any damages. Use of this program is at your own risk. May cause rifts in space
-and time.

-                           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<ret>
-or
-      ddtz [d:]filespec<ret>
-
-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<ret>
-         l<ret>
-         ...modify the code and generally mess about...
-         l<ret>
-
-      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.

+                    GNU AFFERO GENERAL PUBLIC LICENSE
+                       Version 3, 19 November 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+                            Preamble
+
+  The GNU Affero General Public License is a free, copyleft license for
+software and other kinds of works, specifically designed to ensure
+cooperation with the community in the case of network server software.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+our General Public Licenses are intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.
+
+  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
+them 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.
+
+  Developers that use our General Public Licenses protect your rights
+with two steps: (1) assert copyright on the software, and (2) offer
+you this License which gives you legal permission to copy, distribute
+and/or modify the software.
+
+  A secondary benefit of defending all users' freedom is that
+improvements made in alternate versions of the program, if they
+receive widespread use, become available for other developers to
+incorporate.  Many developers of free software are heartened and
+encouraged by the resulting cooperation.  However, in the case of
+software used on network servers, this result may fail to come about.
+The GNU General Public License permits making a modified version and
+letting the public access it on a server without ever releasing its
+source code to the public.
+
+  The GNU Affero General Public License is designed specifically to
+ensure that, in such cases, the modified source code becomes available
+to the community.  It requires the operator of a network server to
+provide the source code of the modified version running there to the
+users of that server.  Therefore, public use of a modified version, on
+a publicly accessible server, gives the public access to the source
+code of the modified version.
+
+  An older license, called the Affero General Public License and
+published by Affero, was designed to accomplish similar goals.  This is
+a different license, not a version of the Affero GPL, but Affero has
+released a new version of the Affero GPL which permits relicensing under
+this license.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+                       TERMS AND CONDITIONS
+
+  0. Definitions.
+
+  "This License" refers to version 3 of the GNU Affero General Public License.
+
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
+
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
+
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
+
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
+
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
+
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
+
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
+
+  1. Source Code.
+
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
+
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
+
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
+
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
+
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
+
+  The Corresponding Source for a work in source code form is that
+same work.
+
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey 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;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
+this License.
+
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If 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 convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
+
+  13. Remote Network Interaction; Use with the GNU General Public License.
+
+  Notwithstanding any other provision of this License, if you modify the
+Program, your modified version must prominently offer all users
+interacting with it remotely through a computer network (if your version
+supports such interaction) an opportunity to receive the Corresponding
+Source of your version by providing access to the Corresponding Source
+from a network server at no charge, through some standard or customary
+means of facilitating copying of software.  This Corresponding Source
+shall include the Corresponding Source for any work covered by version 3
+of the GNU General Public License that is incorporated pursuant to the
+following paragraph.
+
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the work with which it is combined will remain governed by version
+3 of the GNU General Public License.
+
+  14. Revised Versions of this License.
+
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU Affero 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 that a certain numbered version of the GNU Affero General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU Affero General Public License, you may choose any version ever published
+by the Free Software Foundation.
+
+  If the Program specifies that a proxy can decide which future
+versions of the GNU Affero General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
+
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
+
+  15. Disclaimer of Warranty.
+
+  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.
+
+  16. Limitation of Liability.
+
+  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
+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.
+
+  17. Interpretation of Sections 15 and 16.
+
+  If the disclaimer of warranty and limitation of liability provided
+above cannot be given local legal effect according to their terms,
+reviewing courts shall apply local law that most closely approximates
+an absolute waiver of all civil liability in connection with the
+Program, unless a warranty or assumption of liability accompanies a
+copy of the Program in return for a fee.
+
+                     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
+state the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software: you can redistribute it and/or modify
+    it under the terms of the GNU Affero General Public License as published
+    by the Free Software Foundation, either version 3 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 Affero General Public License for more details.
+
+    You should have received a copy of the GNU Affero General Public License
+    along with this program.  If not, see <https://www.gnu.org/licenses/>.
+
+Also add information on how to contact you by electronic and paper mail.
+
+  If your software can interact with users remotely through a computer
+network, you should also make sure that it provides a way for users to
+get its source.  For example, if your program is a web application, its
+interface could display a "Source" link that leads users to an archive
+of the code.  There are many ways you could offer source, and different
+solutions will be better for different programs; see section 13 for the
+specific requirements.
+
+  You should also get your employer (if you work as a programmer) or school,
+if any, to sign a "copyright disclaimer" for the program, if necessary.
+For more information on this, and how to apply and follow the GNU AGPL, see
+<https://www.gnu.org/licenses/>.

+
+                         Generic CP/M Version 3.00
+
+                    (C) Copyright R.T.Russell 1982-1999
+
+1. INTRODUCTION
+
+   BBC  BASIC (Z80) has been designed to be as compatible as  possible  with 
+   Version 4 of the 6502 BBC BASIC resident in the BBC Micro Master  series.  
+   The language syntax is not always identical to that of the 6502  version, 
+   but in most cases the Z80 version is more tolerant.
+
+   BBC  BASIC (Z80) is as machine independent as possible and, as  supplied, 
+   it  will  run  on any CP/M 2.2 (or later) system using  a  Z80  processor 
+   (checks  are carried out to ensure that the processor is a Z80  and  that 
+   the version of CP/M is at least 2.2).  It is minimally configured for  an 
+   ADM3a-compatible VDU.
+
+   Few  CP/M  systems  offer  colour graphics of  the  quality  provided  as 
+   standard  on  the BBC Microcomputer, and no software can  provide  colour 
+   high-resolution graphics from a monochrome character-orientated computer.  
+   However,  many CP/M system users are interested in the  advanced  program 
+   structures  available from BBC BASIC and, within the limitations  of  the 
+   host  computer, BBC BASIC (Z80) provides the programming  structures  and 
+   the non-graphic commands and functions specified for BBC BASIC.
+
+   In order to make full use of the facilities available in BBC BASIC  (Z80) 
+   it is necessary to install a small patch to adapt it to the  capabilities 
+   of  the  host  computer.  The source code of the  patch  present  in  the 
+   distribution version is supplied as BBCDIST.MAC.
+
+   This  documentation  should be read in conjunction with  a  standard  BBC 
+   BASIC  manual.  Only those features which differ from the standard  Acorn 
+   versions are documented here.
+
+
+2. MEMORY UTILISATION
+
+   BBC  BASIC (Z80) requires about 16 Kbytes of code space, resulting  in  a 
+   value  of  PAGE  of about &3E00.  The remainder of  the  user  memory  is 
+   available  for BASIC programs, variables (heap) and stack.  Depending  on 
+   the system configuration, HIMEM can have a value up to &FE00.
+
+
+3. COMMANDS, STATEMENTS AND FUNCTIONS
+
+   The syntax of BASIC commands,  statements and functions is in most  cases 
+   identical  to  that  of  the  BBC  Micro  version  (BASIC  4).   The  few 
+   differences are documented here:
+
+   ADVAL
+   This function is not implemented.
+
+   CALL
+   CALL  sets  up a table in RAM containing details of the  parameters;  the 
+   processor's  IX register is set to the address of this  parameter  table.  
+   The other processor registers are initialised as follows:
+
+               A is initialised to the least significant byte of A%
+               B is initialised to the least significant byte of B%
+               C is initialised to the least significant byte of C%
+               D is initialised to the least significant byte of D%
+               E is initialised to the least significant byte of E%
+               F is initialised to the least significant byte of F%
+               H is initialised to the least significant byte of H%
+               L is initialised to the least significant byte of L%
+
+   The parameter types are:
+
+          Code No.       Parameter Type      Example
+              0          Byte (8 bits)       ?A%
+              4          Word (32 bits)      !A% or A%
+              5          Real (40 bits)      A
+            128          Fixed string        $A%
+            129          Movable string      A$
+
+   On  entry  to the subroutine the parameter table contains  the  following 
+   values:
+
+          Number of parameters     1 byte (at IX)
+
+          Parameter type           1 byte (at IX+1)
+          Parameter address        2 bytes (at IX+2, IX+3, LSB first)
+
+          Parameter type           ) repeated as often as necessary
+          Parameter address        )
+
+   Except  in  the case of a movable string (normal  string  variable),  the 
+   parameter  address  given is the absolute address at which  the  item  is 
+   stored.  In the case of movable strings (type 129) it is the address of a 
+   4-byte parameter block containing the current length, the maximum  length 
+   and the start address of the string (LSB first) in that order.
+
+   Integer  variables  are stored in twos complement form with  their  least 
+   significant byte first.
+
+   Fixed  strings are stored as the characters of the string followed  by  a 
+   carriage return (&0D).
+
+   Floating point variables are stored in binary floating point format  with 
+   their least significant byte first; the fifth byte is the exponent.   The 
+   mantissa  is  stored as a binary fraction in sign and  magnitude  format.  
+   Bit 7 of the most significant byte is the sign bit and, for the  purposes 
+   of calculating the magnitude of the number, this bit is assumed to be set 
+   to  one.  The exponent is stored as an integer in excess 127  format  (to 
+   find the exponent subtract 127 from the value in the fifth byte).
+
+   If the exponent byte of a floating point number is zero, the number is an 
+   integer stored in integer format in the mantissa bytes.  Thus an  integer 
+   can be represented in two different ways in a real variable.  For example 
+   the value +5 can be stored as:
+
+            05 00 00 00 00         Integer 5
+            00 00 00 20 82         (0.5 + 0.125) * 2^3
+
+   COLOUR (COLOR)
+   This statement is not implemented.
+
+   DRAW
+   This statement is not implemented.
+
+   EDIT
+   A command to edit or concatenate and edit the specified program  line(s).  
+   The specified lines (including their line numbers) are listed as a single 
+   line.   By changing only the line number you can use EDIT to duplicate  a 
+   line.
+
+     EDIT 230
+     EDIT 200,230
+
+   The  following control functions are active both in the EDIT mode and  in 
+   the immediate entry mode (i.e. at the BASIC prompt):
+
+     Move the cursor one character position to the left
+     Move the cursor one character position to the right
+     Move the cursor to the start of the line
+     Move the cursor to the end of the line
+     Insert a space at the current cursor position
+     Delete the character at the current cursor position
+     Backspace and delete the character to the left of the cursor
+     Delete all characters to the left of the cursor
+     Delete all characters from the cursor to the end of the line
+
+   The choice of which keys activate these functions is made when BBC  BASIC 
+   is configured for a particular system.  The distribution version uses ^H, 
+   ^I, ^K, ^J, ^A, ^E, DEL (&7F), ^L and ^X.
+
+   To exit EDIT mode and replace the edited line, type RETURN (ENTER).
+
+   To abort the edit and leave the line unchanged, type ESCape.
+
+   ENVELOPE
+   This statement is not implemented.
+
+   GET
+   This  function  waits for a character to be typed at  the  keyboard,  and 
+   returns the ASCII code.
+
+   GET can also be used to read data from a processor I/O port; full  16-bit 
+   port addressing is available:
+
+          N% = GET(X%) : REM input from port X%
+
+   INKEY
+   This function waits for a specified maximum number of centiseconds for  a 
+   character to be typed at the keyboard.  If no character is typed in  that 
+   time, the value -1 is returned.  In the distribution version the delay is 
+   determined by a simple software timing loop, and may be very  inaccurate.  
+   The customisation patch allows this to be adjusted to suit the system  in 
+   use.
+
+   INPUT#
+   The format of data files is different from that used by the BBC Micro, in 
+   part  to improve compatibility with standard CP/M files.  Numeric  values 
+   are  stored  as five bytes in the format documented under  CALL;  if  the 
+   fifth  byte is zero the value is an integer.  Strings are stored  as  the 
+   characters  of the string (in the correct order!) followed by a  carriage 
+   return (&0D).
+
+   MODE
+   This statement is not implemented.
+
+   MOVE
+   This statement is not implemented.
+
+   PLOT
+   This statement is not implemented.
+
+   POINT
+   This function is not implemented.
+
+   PRINT#
+   The format of data files is different from that used by the BBC Micro, in 
+   part  to improve compatibility with standard CP/M files.  Numeric  values 
+   are  stored  as five bytes in the format documented under  CALL;  if  the 
+   fifth  byte is zero the value is an integer.  Strings are stored  as  the 
+   characters  of the string (in the correct order!) followed by a  carriage 
+   return (&0D).
+
+   PUT
+   A  statement to output data to a processor port.  Full 16-bit  addressing 
+   is available.
+
+          PUT A%,N% : REM Output N% to port A%
+
+   SOUND
+   This statement is not implemented.
+
+   TIME
+   This pseudo-variable is not implemented in the distribution version,  but 
+   can be supported by means of the customisation patch.  See BBCDIST.MAC.
+
+   USR
+   As with CALL, the processor's registers are initialised as follows:
+
+               A is initialised to the least significant byte of A%
+               B is initialised to the least significant byte of B%
+               C is initialised to the least significant byte of C%
+               D is initialised to the least significant byte of D%
+               E is initialised to the least significant byte of E%
+               F is initialised to the least significant byte of F%
+               H is initialised to the least significant byte of H%
+               L is initialised to the least significant byte of L%
+
+   USR returns a 32-bit integer result composed of the processor's H, L,  H' 
+   and L' registers, with H being the most significant.
+
+
+4. RESIDENT Z80 ASSEMBLER
+
+   The  in-line  assembler is accessed in exactly the same way as  the  6502 
+   assembler  in  the BBC Micro version of BBC BASIC.  That is,  '['  enters 
+   assembler mode and ']' exits assembler mode.
+
+   All  standard  Zilog  mnemonics are accepted: ADD, ADC and  SBC  must  be 
+   followed by A or HL.  For example, ADD A,C is accepted but ADD C is  not.  
+   However, the brackets around the port number in IN and OUT are  optional.  
+   Thus  both OUT (5),A and OUT 5,A are accepted.  The instruction IN  F,(C) 
+   is not accepted, but the equivalent code is produced from IN (HL),C
+
+   The pseudo-ops DEFB, DEFW and DEFM are included.  DEFM works like EQUS in 
+   the 6502 version.
+
+
+5. OPERATING SYSTEM INTERFACE
+
+   The   following   resident  Operating  System   ("star")   commands   are 
+   implemented.  They may be accessed directly (e.g. *BYE) or via the  OSCLI 
+   statement (OSCLI "BYE").
+
+   Control characters, lower-case characters, DEL and quotation marks may be 
+   incorporated in filenames by using the 'escape' character '|'.   However, 
+   there is no equivalent to the BBC Microcomputer's '|!' to set bit 7.
+
+   *BYE
+   Returns control to the operating system (CP/M).
+
+   *CPM
+   Same as *BYE.
+
+   *. [filespec]
+   *DIR [filespec]
+   List  the  files which match the (optional) ambiguous  filespec.  If  the 
+   filespec is omitted, all .BBC files are listed:
+               *DIR           List all .BBC files on the disk
+               *DIR B:*.*     List all files on disk B:
+               *.*.*          List all files on the current disk
+
+   *DRIVE d:
+   Select drive d as the default drive for subsequent disk operations.
+
+   *ERA filespec
+   Erase (delete) the specified disk file or files.  The extension  defaults 
+   to .BBC if omitted.
+
+   *ESC [ON|OFF]
+   *ESC OFF disables the abort action of the ESCape key; after *ESC OFF  the 
+   ESCape  key  simply returns the ASCII code ESC (27).  *ESC ON,  or  *ESC, 
+   restores the normal action of the ESCape key.
+
+   *EXEC filespec
+   Accept  console  input  from  the  specified file  instead  of  from  the 
+   keyboard. If the extension is omitted, .BBC is assumed.
+
+   *LOAD filespec aaaa
+   Loads  the specified file into memory at address aaaa. The  load  address 
+   must be specified. If the extension is omitted, .BBC is assumed.
+
+   *OPT [n]
+   Select  the destination for console output characters.  The value n is in 
+   the range 0 to 2, as follows:
+               
+          0    Send characters to the console output
+          1    Send characters to the auxiliary output
+          2    Send characters to the printer (list) output
+
+   *REN newfile=oldfile
+   *RENAME newfile=oldfile
+   Renames  'oldfile'  as 'newfile'.  If the extension is omitted,  .BBC  is 
+   assumed.
+
+   *RESET
+   Rest the disk system (CP/M function 13).  This command does not close any 
+   files  nor does it perform any other housekeeping function.   You  should 
+   use *RESET after you have changed a disk.
+
+   *SAVE filespec aaaa bbbb
+   *SAVE filespec aaaa +llll
+   This command saves a specified range of memory to disk. The address range 
+   is  specified either as start (aaaa) and end+1 (bbbb) or as start  (aaaa) 
+   and length (llll). If the extension is omitted, .BBC is assumed.
+
+   *SPOOL [filespec]
+   Copy all subsequent console output to the specified file. If the filename 
+   is omitted,  any current spool file is closed and spooling is terminated. 
+   If the extension is omitted, .BBC is assumed.
+
+   *TYPE filespec
+   Type the specified file to the screen. If the extension is omitted,  .BBC 
+   is assumed.
+
+   *| comment
+   This is a comment line. Anything following the | is ignored.
