- COMP is a CP/M utility which can be used to compare two CP/M files
- (which will usually binary .COM object code files) to find any
- differences between them. The files are compared byte for byte. No
- attempt is made to vary the match points to establish a different
- synchronization if a prolonged mismatch is found, as would be done for
- ASCII files when using DIF2, etc.
-
- The command line usage is:
-
- comp [d:]file1[.typ] [d:]file2[.typ]
-
- The drive specification is optional, if not specified the logged in
- drive is assumed. The file type specification is also optional for
- either file, if not specified, "COM" is assumed.
-
- Discrepancies will be noted at the console in a line of the form:
-
- xxxx yy zz
-
- where xxxx is the number of the discrepant byte, yy in file1, zz in
- file2. Pressing any key at the console will stop the comparison, but in
- any event there will be a final total shown of the bytes compared and
- the number of mismatches encountered.
-
- Note: This program starts the display of any discrepancies at page 1
- (0100H) rather than at page 0 (0000H). This gives absolute addresses
- for normal CP/M files which permits easy use of DDT or SID or an
- assembled print copy to check the discrepancies. Relative addresses are
- relatively worthless for this purpose.
-
- If for some reason you want relative addresses, change the label area
- RPRT1: INR H to RPRT1: DB 0 instead. Then reassemble and reload.
