- COMPHEX is an MS-DOS 2.0 or greater file utility designed to compare two Intel
- format hex files in such a way as to determine whether they would produce
- identical ROMs. The maximum object module size is 7EA7 hex. This is 159 hex
- (345 decimal) bytes short of a 27256 EPROM.
-
- The command syntax is:
-
- [d:]comphex [d:]filespecA [d:]filespecB
-
- where [d:] is an optional drive designator, filespecA is the path and file
- name of the first input file, and filespecB is the path and name of the
- second output file.
-
- COMPHEX writes filenames, mismatches and a summary to standard output. The
- following is a sample output:
-
- FILE A = allz80a.hex
- FILE B = allz80b.hex
-
- ADDR FILE A FILE B
