+## Proxy Functions
+
+The following special functions are implemented inside of the HBIOS
+proxy area at the top of RAM.  They do not cause a bank switch and are,
+therefore, much faster than their corresponding HBIOS API functions.
+
+The functions are invoked via the following dedicated jump table:
+
+| **Function**                           | **Address**   | ** Equate **           |
+|----------------------------------------|---------------|------------------------|

+| Bank Select (BNKSEL)                   | 0xFFF3        | HB_BNKSEL              |
+| Bank Copy (BNKCPY)                     | 0xFFF6        | HB_BNKCPY              |
+| Bank Call (BNKCALL)                    | 0xFFF9        | HB_BNKCALL             |
+
+The function addresses are also defined as equates in hbios.inc.  It
+is suggested that you use the equates when possible.
+
+To use the functions, you may either call or jump to them.  Some
+examples:
+
+```
+        CALL    $FFF0
+        JP      $FFF3
+        CALL    HB_BNKCPY
+```
+
+These functions are inherently dangerous and generally not value
+checked.  Use with extreme caution.
+
+### Invoke HBIOS Function (INVOKE)
+
+**Address 0xFFF0**
+
+This function is an alternate mechanism for invoking the normal HBIOS
+API functions.  The parameters and return values are as documented
+above.  To put it another way, `CALL $FFF0` is equivalent to `RST 08`,
+but it can be used in any scenario when the normal bank is not
+selected.

+| HB_DSTBNK: Destination Bank ID         |                                        |
+
+This function will copy Count (BC) bytes from Source Address (HL) in 
+Source Bank ID (HB_SRCBNK) to Destination Address (DE) in Destination 
+Bank ID (HB_DSTBNK).  The HB_SRCBNK and HB_DSTBNK fields are dedicated 
+locations in the proxy.  These locations are defined in hbios.inc:
+
+- Source Bank ID: `HB_SRCBNK` = $FFE4
+- Destination Bank ID: `HB_DSTBNK` = $FFE7
+
+The Source Bank ID and Destination Bank ID values must be populated in
+the specified addresses before calling this function.
+
+During processing, HL and DE, will be incremented.  At termination,
+HL and DE will contain the "next" source/destination addresses that
+would be copied.  This allows this function to be invoked repeatedly
+to copy continuous blocks of data.
+
+Register AF is destroyed by this function.  Register BC will be 0.

+bank.  It does this by selecting the Target Bank ID (A) and then
+calling the Target Address (IX).  On return from the target function,
+the originally active bank is selected.
+
+Register usage is determined by the routine that is called.
+
+Since a different bank will be selected while the target function is
+active, the warnings described in

+## Console Takeover
+
+If your system has more than one character unit, then the Boot Loader 
+will "poll" all of the character devices for a request to make any of 
+the alternate character devices the active console.  This is called a 
+console takeover request.  This functionality must be enabled in the ROM
+build configuration, but currently it is for all standard ROMs.
+
+To request a console takeover, you just press the \<space\> character 
+twice in a row at the port or terminal that you want to move the console
+to.  The terminal or communication software **must** be configured for 
+the default serial port speed and data bits for this to work.
+
+A takeover request is only possible while the active console is
+showing the Boot Loader prompt prior to typing any characters at
+the active console.  In other words, once you start typing at the
+active console prompt, the takeover polling is suspended.  If you have
+started typing characters, you can press \<enter\> at the active
+console to get a fresh Boot Loader prompt and reactivate the polling.
+
+If you have built a custom ROM that includes an automatic boot
+command with a timeout, then performing a console takeover will

+network using MT011 with RomWBW.
 
 ## CP/NET Client Setup
 
 The CP/NET client files are included on the RomWBW disk images, but
 they are found in user area 4.  They are placed there to avoid
 confusing anyone that is not specifically trying to run a network
-client.
+client.  They are only found on the CPM 2.2 and CP/M 3 slices.  Using
+CP/NET on alternative OSes may work, but is not officially supported.
+
+The CP/NET client files are packaged in `.LBR` library files.  The
+library files are found in user area 4.
+
+| File         | CP/NET Version | OS       | Hardware              |
+|--------------|----------------|----------|-----------------------|
+| CPN12MT.LBR  | CP/NET 1.2     | CP/M 2.2 | RCBus w/ MT011        |
+| CPN3MT.LBR   | CP/NET 3       | CP/M 3   | RCBus w/ MT011        |
+| CPN12DUO.LBR | CP/NET 1.2     | CP/M 2.2 | Duodyne w/ Disk I/O   |
+| CPN3DUO.LBR  | CP/NET 3       | CP/M 3   | Duodyne w/ Disk I/O   |
+
+First, you need to merge the files from the correct library file
+into user area 0.  This is done by extracting the files using the
+`NULU` library management utility application.
+
+1. Start NULU specifying desired CP/NET library for \<filename\>:
+
+   `A>NULU 4:<filename>`
+
+2. At the NULU prompt, extract the files using the `-E *.*` command:
+
+   `-READY A0:>-E *.*`
 
-First, you need to merge the files from user area 4 into user area 0.
-After booting into Z-System (disk boot), you can copy the files
-using the following command:
+3. Exit NULU using the `-X` command:
 
-`COPY 4:*.* 0:`
+   `-Extract members A0:>-x`
 
-You will be asked if you want to overwrite `README.TXT`.  It doesn't
-really matter, but I suggest you do not overwrite it.
+Here is an example of extracting the CP/NET 1.2 client files for an 
+RCBus system w/ MT011.  You should be in user area 0 when performing 
+this operation.
 
-The MT011 Module uses a WizNet network module.  At this point, you will 
-need to configure it for your local network.  The definitive guide to 
-the use of `WIZCFG` is on the

+===== Cowgol 2.0 for CP/M =====
+
+This disk contains the Cowgol 2.0 compiler and related tools.
+These files were provided by Ladislau Szilagyi and were sourced
+from his GitHub repository at https://github.com/Laci1953/Cowgol_on_CP_M.
+
+The COWFE program included here is the RomWBW-specific version that
+is tailored to RomWBW memory management.
+
+The primary distribution site for Cowgol 2.0 is at
+https://github.com/davidgiven/cowgol.
+
+The Hi-Tech C compiler components were sourced from the updated
+version by Tony Nicholson at https://github.com/agn453/HI-TECH-Z80-C.
+However, the CPP.COM component was sourced from Ladislau Szilagyi's
+enhanced Hi-Tech C at https://github.com/Laci1953/HiTech-C-compiler-enhanced.
+
+Note that only the minimum required Hi-Tech C compiler components
+are provided.  Additional components from Hi-Tech C may be required
+depending on your needs.
+
+There are two example Cowgol applications included:
+
+- HEXDUMP is a simple hex dump utility and is purely a Cowgol
+  application (no assembler or C components).  The command
+  line to build the application is:
+
+    COWGOL HEXDUMP.COW
+
+- DYNMSORT demonstrates a sort algorithm and is composed of
+  Cowgol, C, and assembler components.  The command line to
+  build the application is:
+
+    COWGOL -LC DYNMSORT.COW MERGES.C RAND.AS
+
+There are also SUBMIT files provided to build the example
+applications which can be used as follows:
+
+    SUBMIT HEXDUMP
+    SUBMIT DYNMSORT

-Some changes have been made to COPY since the manual was written.  
-Comparison of dates with Existence testing ON has been changed to 
-use the Creation date when no Modified date exists, and print 
-"Undated" when neither exists, yet both source and destination 
-disks support file date stamping.  Additionally, the /X option 
-has been re-defined, and a new /R option has been added to 
-Version 1.4.  Please replace Paragraph 4.1.2.9 on page 55 of your 
-ZSDOS manual with the following two paragraphs describing the new 
-options.
-
-
-4.1.2.9.1  ERASE SOURCE FILE AFTER COPY.
-
-When you want to "move" a file from one area to another, the "X" 
-option may be used.  This option causes a file or group of files 
-to be copied in the manner described by the default or specified 
-options, but after the copy and optional verify, the source file 
-or files are erased.  You will be notified that the file has been 
-erased by the status "(X)" being printed on your console.  To 
-minimize the possibility of deleting a good file when errors 
-exist in the copy, the Verify option should always be active, 
-either by default, or specified.  When Verify is active, any 
-errors detected will disable the "X" option for that file so that 
-a good source file will not be deleted.  The "X" option has no 
-configurable value, and is always assumed to be "Off" requiring 
-the option in the command line list to be effective.
-
-
-4.1.2.9.2  COPY ONLY FILES WHICH EXIST (REPLACE).
-
-Occasionally, you may wish to update selected files to a destina- 
-tion in a simpler manner than naming each file, or using the 
-Inspect option.  The "R" (Replace) option, when active, tells 
-COPY to transfer only files which exist on the destination direc- 
-tory.  If the Archive option (A) is added in conjunction with the 
-Replace option, only files which have not been archived, AND 
-already exist on the destination will be archived.  It should be 
-noted that the No Replacement (N) option is incompatible with 
-both the Replace and Archive options, and is disabled when either 
-"R" or "A" are active.

-                           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.

-      A ZSDOS utility, copyright (c) 1988 by Carson Wilson.
-
-
-FILEATTR (FA) is a utility that allows rapid settin, resetting, 
-or displaying of file attributes under ZSDOS, ZRDOS, and CP/M 
-2.2.  Several additional features are available under ZCPR3, 
-including error flag setting, error handler invocation, an 
-enhanced display, and better error detection.
-
-FA will not run under CP/M 3.0 or Z3PLUS.
-
-USAGE:
-
-     FILEATTR {dir:}{afn} {{/}options}
-
-If a DIR or DU specification is not given, the current directory 
-is assumed (under vanilla CP/M only the drive is significant).  
-If no ambiguous or unambiguous filename is given, all files 
-("*.*") are matched.
-
-If no attribute options are given, FILEATTR merely displays the 
-current state of each file's attributes.  Files are displayed in 
-the order that they appear in the directory.
-
-Once operation begins, FA cannot be aborted by the user.  If a ^C 
-is entered at the keyboard, all screen output stops, but file 
-attribute operations continue to completion.  If that was not the 
-case, attributes might be set on some entries for a file and not 
-on others.  Nevertheless, suppressing screen output speeds things 
-up a bit.
-
-OPTIONS:  A leading slash is required unless the option list is 
-the second parameter on the command line.  Options may be 
-separated by spaces, commas, or nothing at all.
-
-ATTRIBUTE OPTIONS:  These options set (turn on) corresponding 
-attributes on files matching the file specification.  Attributes 
-not specified by an attribute option remain unchanged.
-
-If the option is preceded by a minus ("-") or by an "N", the 
-corresponding attribute is reset (turned off).
-
-     1    F1.  This is a user attribute which has no predefined 
-          meaning.
-
-     P    Public (f2).  Under ZSDOS, when this attribute is set, 
-          a file is available from any user area of the disk on 
-          which it resides.  A file cannot be made public if 
-          another file with the same name exists in any other 
-          user area on that drive.  In that case FA will issue an 
-          error message and leave the attribute off.
-
-     D    Inhibit access datestamp (f3).  Under ZSDOS, when this 
-          attribute is set, the file's access datestamp will not 
-          be updated, which may speed file access slightly.  If 
-          the attribute is turned off, normal access datestamping 
-          resumes.
-
-     4    F4.  This is a user attribute which has no predefined 
-          meaning.
-
-     W    Wheel protect (f8).  Under ZSDOS, when this attribute 
-          is set, the file becomes read-only when the wheel byte 
-          is off and cannot be erased.  If the wheel byte is on, 
-          the file can be erased normally.
-
-     R    Read only (t1).  When this attribute is set, the file 
-          cannot be erased or modified by most programs.
-
-     S    System (t2).  When this attribute is set, the file 
-          becomes a "hidden" file that will not be found by most 
-          directory programs or by most well-behaved utilities 
-          that accept ambiguous filenames.  (FA must find system 
-          files, of course.)
-
-     A    Archive (t3).  When this attribute is set, it signals 
-          some archival programs that the file has not been 
-          modified since it was last backed up.  If a file is 
-          modified, ZSDOS and ZRDOS turn this attribute off.  
-          CP/M does not fully support this attribute, however.
-
-OTHER OPTIONS:  These options affect only the screen display.
-
-     Q    Quiet mode.  Console output is suppressed unless there 
-          is an error.  All other operations are performed 
-          normally.
-
-     X    Screen paging off.  With this option, screen paging is 
-          turned off.  The screen can still be paused by pressing 
-          any key except ^C.
-
-ERRORS:  Under ZCPR3, errors will cause FA to set the program 
-error flag and to invoke the error handler.  The error flag will 
-be set to the following values:
-      2   invalid directory specification
-      4   miscellaneous (conflicting file, no files on disk)
-     10   no matching files found (no error handler)
-     18   Disk read-only
-     19   Invalid option
-
-For error code 10 (no matching files found), the error flag is 
-set, but the error handler is not called.
-
-In addition, under ZCPR 3.3 and above, an invalid directory 
-specification will abort FA to the error handler, but no message 
-is printed.
-
-The following error messages may be seen:
-
-Conflicting entry, can't set public attribute
-     If there are files with the same name in other user areas of 
-     the disk, the public attribute cannot be set.
-
-No files on disk
-     The disk directory is empty.
-
-Bad Option: /o
-     The command line option shown is unknown to FILEATTR.
-
-Drive R/O
-     The drive is set to read-only by the operating system and 
-     attributes cannot be changed.
-
-CP/M version 2.x required
-     FILEATTR will not run on this system.
-
-BIOS write error near directory sector n
-     An error occurred at or near the given directory sector, 
-     which is expressed as a decimal offset from the beginning of 
-     the directory.
-
-BIOS set track detected - FA aborting
-     A background program is attempting to modify the current 
-     track setting.  The background program must be removeed 
-     before running FA again.
-     
-Not Wheel
-     Under ZCPR3 the wheel byte must be set before FILEATTR can 
-     be run.
-
-CONFIGURATION:  While no installation is necessary, all options 
-can be set as defaults, if you prefer, using ZCNFG.  The 
-configuration options are fully explained on the ZCNFG help 
-screens.
-
-It is best not to change the name of the configuration file.  Its 
-special name assures that ZCNFG will always find the correct CFG 
-file, even if the name of FA has been changed or if more than one 
-version of FA is online.
-
-HISTORY:
-
-Version 1.6 -- April 14, 1991 -- Gene Pizzetta
-     Now displays target DU and directory name in summary.  Fixed 
-     bug that caused "GO" to be displayed as program name, if it 
-     was re-invoked with the GO command.
-
-Version 1.5 -- March 27, 1991 -- Gene Pizzetta
-     Now calls CP/M version checking routine (it was there, but 
-     it wasn't called).  Changed error codes:  10, no matching 
-     files found.  "No files on disk" error now gets 
-     miscellaneous error code (4).  Error 10 does not invoke 
-     error handler.  Not released.
-
-Version 1.4 -- March 20, 1991 -- Gene Pizzetta, Howard Goldstein
-     Code to check module data byte (S2) was replaced by Howard 
-     Goldstein's elegant solution which uses a "true" extent 
-     number:  ((data_mod * 32) + extent).  Entering a ^C no 
-     longer really aborts FILEATTR; instead FA immediately prints 
-     "Wait..." on the screen, turns off paging, turns on quiet 
-     mode, sets the results flag, and finishes what it was doing. 
-     All this is to prevent unexpected results when only some of 
-     a file's directory entries are changed.  All errors 
-     including a conflicting file found during a PUBLIC request, 
-     now set the program error flag and invoke the error handler 
-     so an active SUBMIT or ZEX script can be aborted.  The error 
-     flag will have the following values:  2, invalid directory; 
-     10, no files on disk; 18, disk is read-only; 19, invalid 
-     option; 4, all other errors.  If no matching files are 
-     found, the program error flag will be set to FFh, but the 
-     error handler will not be invoked.  A few other code changes 
-     were made, including a check for CP/M-Plus, under which 
-     FILEATTR will not work.  Not released.
-
-Version 1.3 -- February 22, 1991 -- Gene Pizzetta
-     Corrected bug that caused faulty operation on large files:  
-     The module data byte (S2) byte was not being checked, so 
-     such files appeared 2 or more times in the directory display 
-     and the public routine was often not finding conflicting 
-     files.  Added configuration byte and command line option (X) 
-     for screen paging (paging is suppressed in quiet mode).  
-     Made quiet mode responsive to ZCPR quiet flag and changed Q 
-     command line option to toggle.  Usage screen reflects 
-     current effect of X and Q toggles.  Attribute configuration 
-     area changed to be compatible with ZCNFG TOGL3 routine.  
-     Actions of D and ND options reversed so they work the same 
-     as the others.  Added configuration byte for printing 
-     summary line even in quiet mode, as suggested by Howard 
-     Goldstein.  Removed blank lines from screen display, 
-     allowing three more filenames to be shown.  Removed tabs 
-     from usage screen so PRINT and PSTR are not needed.  
-     Eliminated leading zero from user number display.  Now 
-     prints "file" instead of "files" in summary when only 1 
-     matching file is found.  Ditto for attribute(s) altered.
-
-Version 1.2 -- November 30, 1988 -- Carson Wilson
-     Fixed bug of no program name display when FILEATTR's name 
-     was 8 characters long.
-
-Version 1.1 -- October 30, 1988 -- Carson Wilson
-     Now wildcards the command forms "FA d: /options" and "FA d: 
-     options."
-
-Version 1.0 -- September 26, 1988 -- Carson Wilson
-     If a filespec is given, no leading slash is required before 
-     the options.  Link with version 4 libraries.  Removed /X 
-     option--ZSDOS 10T always closes the first extent when a file 
-     is written to.  Changed summary to read "files matched".
-
-Version 0.9 -- July 7, 1988 -- Carson Wilson
-     Increased length of search FCB (AMBFIL) by one byte.  Set up 
-     AMBFIL as '?' + 35 binary 0's.  ZRDOS and CP/M zero the 
-     drive byte (FCB+0) during search next calls, so reinitialize 
-     it to '?' before rescanning the directory.  PROGID now 
-     prints stored name on GO/JUMP.
-
-Version 0.8 -- June 26, 1988 -- Carson Wilson
-     Use SYSLIB PRINT for help display.  VPRINT does not expand 
-     tabs.  Now traps disk track changes at the BIOS level.  
-     Allows '-' as well as 'N' for "negate option." Auto- 
-     wildcards FCB1 for attribute set as well as display.
-
-Version 0.7 -- May 24, 1988 -- Carson Wilson
-     Cosmetic changes to help, display.  Made public routines 
-     faster by 1/2 directory scan average.  Consolidated file 
-     attribute setting/resetting routines for efficiency and 
-     clarity.
-
-Version 0.6 -- May 14, 1988 -- Carson Wilson
-     Changed "Publ" to "Publc" and "Priv" to "Privt".  Added Q 
-     and X options, made options installable.  Added test for bad 
-     ZCPR directory & chain to error handler.
-
-Version 0.5 -- May 4, 1988 -- Carson Wilson
-     Fixed bug at CHKRO inherited from MAKE.ASM.  Uses Bridger 
-     Mitchell's FRESET to reset disks.  Uses ZCPR invocation name 
-     in signon, help, etc.  Added F4 attribute.  Now includes all 
-     valid ZSDOS attributes.  Help now fully "smart" under ZCPR.  
-     Reworked VID3.Z80 and VID4.Z80 from VLIB11 and moved them 
-     into FA.Z80 (see end of file).  Put STNDOUT mode ON by 
-     default at beginning of each attribute display sequence for 
-     faster ZCPR displays.
-
-Version 0.4 -- April 27, 1988 -- Carson Wilson
-     Tests for matching files at other user areas before setting 
-     the public attribit.
-
-Version 0.3 -- April 26, 1988 -- Carson Wilson

-Option Q -- If the ZCPR quiet flag is set, FILEATTR will always default to 
-quiet mode.  To make quiet mode the default at all times, even when running 
-under CP/M, set this configuration option to "Yes".  Whatever is selected 
-here can be toggled with the command line "Q" option.
-
-Option X -- A "Yes" will cause FILEATTR to page screen output by default.  
-A "No" will default to continuous scrolling.  The chosen default can be 
-toggled with the command line "X" option.  Screen paging is always turned 
-off in quiet mode.
-
-Option R -- As distributed, FILEATTR prints nothing to the screen when it 
-is operating in quiet mode.  If this configuration option is "Yes", the 
-results summary line that gives the number of matching files found and the 
-number of attributes changed will be printed even in quiet mode.
-
-Option S -- Enter the number of lines on your video display screen.  Under 
-ZCPR 3.3 and higher, the number of screen lines for paging is obtained from 
-the environment descriptor.  This configuration parameter is used only if 
-running under CP/M.
-
-
-                      Attribute Configuration Options
-
-As distributed, FILEATTR will not change any file attribute unless 
-explicitly commanded to do so by a command line option.  To configure 
-FILEATTR to turn a file attribute ON or OFF by default, toggle the 
-appropriate configuration selection.
-
-For example, to make FILEATTR set all matching files to Public by default, 
-change the "Public attribute" setting to "Turn On".  Then FILEATTR will set 
-the specified files to Public unless the /NP command line option is given 
-(which would cause the files to be set to Private).  Since there is no 
-command which tells FILEATTR not to change an attribute, however, the 
-program will now insist on turning the Public attribute either on (default) 
-or off (through the /NP option).
-
-Most users will have neither need nor desire to change the configuration 
-default as distributed which will "Leave As-Is" all matching files.
