-
- Tw∩á utilitie≤á arσá provideΣ witΦ ZCPR▓ t∩á comparσá files« ì
- Both utilities are simple in form to use. These utilities are:
-
- COMPARE -- Compares two files by reading one, computing its
- CRC value, saving its CRC and size, and then
- reading the other and seeing if they match
-
- DIFF -- Prints out a difference listing between two files;
- different bytes encountered at the same
- relative displacements from the beginning of
- thσ file≤ arσ printeΣ iε hexadecimal¼
- decimal, and ASCII forms
-
-
- These commands are invoked by the following forms:
-
- COMPARE or COMPARE // <-- Print Help
- COMPARE dir:file1.typ,dir:file2.typ M <-- Compare
-
- DIFF or DIFF // <-- Print Help
- DIFF dir:file1.typ,dir:file2.typ M <-- Compare

- The general form of the CRC command is:
-
- CRC dir:afn1,dir:afn2,... ooo...

- The options available under CRC are:
-
-
- C - Comment Output; the user is given an opportunity
- to enter comments for each file
-
- D - Disk Output; send output to the disk file CRC.CRC
- as well as to the console
-
- I - Inspect and approve file before CRC is computed
-
- P - Printer Output; send output to the printer as
- well as to the console
