1. COMP File Compare

               COMP is a handy utility for comparing any two text files.
          COMP creates a report clearly showing all of the differences
          between the two files.  It can save you hours of time from
          hand-comparing two versions of a file.  It can be used for 

               Batch files           Legal briefs      Newsletters
               Computer programs     Letters           Parts lists
               Contracts             Mailing lists     Reports
               Documents             Manuscripts       Rosters
               Instructions          Memos             Schedules
               Inventories           Messages          Webpages
               Invoices              News articles

          or any other type of text file.

               COMP detects additions, deletions and changes of as little
          as a single letter, or as much as 50 lines of text.  It shows all
          of the differences in a clear report that indicates the line
          numbers in both files, and shows both blocks of changed text.
          Even blank lines are clearly indicated.

          1.1. Using COMP

               COMP can be called and used two ways.  You can name the
          files directly in the COMP command, like this 

               comp oldversion newversion

          or you can simply type COMP on the command line and let COMP
          prompt you for the file names, like this 


          You type the file names when COMP requests them, like this 

               File 1: oldversion
               File 2: newversion

               COMP will write the list of differences to the file COMP.LST
          unless you want the list to go to a different file.  You can
          specify your own output file on the command line, like this 

               comp oldfile newfile diff

          or let COMP prompt you for the file, like this 


               File 1: members.old
               File 2: members.new
               Output: changes

          In these examples the list of differences will be written to the
          files DIFF and CHANGES, respectively.  You can view the changes
          with any text editor, such as Edit, Notebook, WordPad or NotePad,
          or with any browser.

          1.2. Installing COMP

               You install COMP by copying it from the distribution disk to
          any place on your computer where you have executable programs.
          For example, to a directory called EXE or COM, or to a folder
          within \Program Files\.

          1.3. Output file

               The difference list in the output file is designed to be
          self-explanatory.  Here is a typical difference list

                 File 1 = DOGS1
