  124.  
  125.  
  126.     ZAP PROGRAM DESCRIPTION        ZAP is a file editor for binary and other
  127.                                    program and data files.  Plus, ZAP can
  128.                                    examine and modify computer memory.
  129.  
  130.  
  131.     General Features               ZAP works with files up to 16 megabytes
  132.                                    minus 512 bytes.
  133.  
  134.                                    ZAP will open a specified file and read a
  135.                                    single 256 byte block of data into memory.
  136.                                    Once in memory, a block can be edited in
  137.                                    Ascii and hexadecimal modes.  A modified
  138.                                    block can be saved back to the file.
  139.  
  140.                                    ZAP can read but can not edit a file that
  141.                                    is flagged by Dos as 'read only'.
  142.  
  143.                                    ZAP can not (will not) extend a file by
  144.                                    writing back more bytes than were read.
  145.  
  146.                                    ZAP works with computer memory up to one
  147.                                    megabyte.
  148.  
  149.                                    Memory blocks of 256 bytes can be edited
  150.                                    and saved back to memory (RAM).
  151.  
  152.                                    ZAP can read but can not write to ROM.
  153.  
  154.                                    ZAP is programmed in Turbo C 2.0, small
  155.                                    memory model for speed, and incorporates
  156.                                    numerous 8086 assembly language functions
  157.                                    in critical sections for even more speed.
  158.  
  159.                                    ZAP was developed on a 286/VGA system and
  160.                                    requires Dos 2.00 plus and 128K of RAM.
  161.  
  162.  
  163.     Some Assumptions               You are reading the documentation for a
  164.                                    program which is designed primarily as a
  165.                                    program and data file maintenance tool.
  166.  
  167.                                    Assumption: you are a programmer or you
  168.                                    are someone who maintains many or large
  169.                                    data files.  To use ZAP effectively, you
  170.                                    need a good understanding of Ascii codes
  171.                                    and the hexadecimal numbering system.
  172.  
  173.                                    If so, ZAP and the remainder of this
  174.                                    brief document is written for you.
