   ZP (Zcpr33+ Patcher) is  a  Z80 screen-oriented  record  editor-patcher.  A
type 3 version (ZP.1OM), running at 100h, and  another (ZP.3OM)  executing  at
8000h, both require ZCPR33+ or Z3PLUS and will not run under straight  CP/M or
ZCPR3.0.   A type 4 version (ZP.4OM) will run  only  under  ZCPR34+ or Z3PLUS.
All versions are  BGii-compatible,  need  an  extended  Z3TCAP  (as defined by
VLIB4D+), and require that the ZCPR3  wheel byte be set.   ZP has a one-record
cache for temporary  record  storage and can move the cache  contents  between
file,  memory and  disk  records.   ZP  also contains the  powerful and  full-
featured HP12 RPN programmer's integer calculator.

 Syntax 

   While ZP  allows the  user  to  freely  switch  among modes  during program
operation, it may be  instructed to  come  up  in  the desired initial mode by
using the following command line syntax:

     ZP             - Memory mode
     ZP dir:        - Disk mode
     ZP [dir:]afn   - File mode

     ZP //          - Display syntax help screen


   See ZP.HLP for details on operation of ZP.COM.

 ZP Notes - 1/2 

   a. Vs 1.5 updates (08/23/91, Terry Hazen):
      - Now highlights start of found string,  specified  address in displayed
        record.

   b. Vs 1.4 updates (07/17/91, Terry Hazen):
      - Corrects problem with bpstr(4), which was still sending hi bits to the
        terminal.  
      - Flags now preserved around curon call at getbuf0(4), avoiding problems
        for terminals such as older Kaypros that don't support cursor on/off.  

   c. Vs 1.3 updates (06/24/91, Terry Hazen):
      - Now uses FFFFh instead of 0000h as default memory mode flag  (dmea) so
        that command line entry of 0 will cause page 0 to be  displayed rather
        than the environment.
      - Modified mbox so ZCNFG can toggle it through 3 options.	
      - Modified VPRINT to filter hi bits  of  characters  being  sent  to the
        terminal for systems that don't like hi bits.  
      - PRSFN now correctly locates files with a U: spec.
 ZP Notes - 2/2 

   d. Vs 1.2 updates (06/12/91, Terry Hazen):
      - Speeded up screen  redisplays by turning off cursor  except  when user
        input is required.  
      - Added the ability to specify the starting  memory  display  address on 
        the command line.
      - Print routines were changed to terminate on either 0 or hi bit set (to
        compensate for extra code and still keep type 3 versions under 8k).
      - Used 'dc'  (same as defc)  to designate strings ending with hi bit set 
        to assembler.

   e. Vs 1.1 udpates (11/16/90, Terry Hazen):
      - Changed initialization to  shorten  code  and  fixed  several glitches
        which crept into vs 1.0 at last minute.
      - '//' help screen now displays proper filename.
      - Revised logging to fix user logging problem.
      - Replaced Z33/34 filename parser with filename parser module  (ZP.2) to
        provide BGii compatibility.
      - Revised string search to match both  upper and lower case buffer chars
        to avoid some problems with false negative matches.
      - Slightly revised header display.
