:File Comparison Utilities Under ZCPR2

     Twï  utilitieó  arå  provideä witè ZCPR² tï  comparå  files®  �
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
                    thå fileó arå printeä iî hexadecimal¬
                    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

     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
