file

   Compares two files, two generations of elements, or a file and
   a generation of an element. If the entities are different, CMS
   creates a file that contains the lines that differ between them.
   If they are the same, CMS issues a message to that effect and does
   not create a differences file (unless the /FULL qualifier is in
   effect).

      Format:

         DIFFERENCES  file1 [file2]
