I would like to take this time to thank all of those who
       answered to my request on help about the Comparison Utility
       Program.

       Harasleben     : POSIX(diff or bc or cmp ).
            Ted Ashton, Tim Ryan, Allen Porter                      :
       Robelle(QEdit, SUPRTOOL).
             Peter Chong, Roy Buzdor                           :
       ALDON(SCompare).

            After some brief research on the subject using the info
       you sent me, it seems ALDON's software would fulfill more my
       expectations.
