      In this example, the DIFFERENCES command compares the contents
      of the two most recent versions of the file EXAMPLE.TXT in the
      current default directory. The DIFFERENCES command compares
      every character in every record and displays the results at the
      terminal.

             DISK1:[CHRIS.TEXT]EXAMPLE.TXT;1

      The DIFFERENCES command compares the same files as in
      Example 1, but lists the differences in both hexadecimal and
      ASCII formats. The command also specifies that default change
      bars be used in the output. The default change bar notation for
      the hexadecimal output is ***CHANGE***. For the ASCII output,
      the default change bar character is the exclamation point.

    3.$ DIFFERENCES/OUTPUT BOSTON::DISK2:TEST.DAT OMAHA::DISK1:[PGM]TEST.DAT

      The DIFFERENCES command compares two remote files and displays
      any differences found. The first file is TEST.DAT on remote
      node BOSTON. The second file is also named TEST.DAT on remote
      node OMAHA. The DIFFERENCES output is located in the file
      DISK1:[PGM]TEST.DIF.
