Format:      DIFF filespec_1 [filespec_2] [/P]


Purpose:     Compares two files and lists the differences.


Use:         DIFF  compares  the  two files, or  one  file  and  its 
        standard  input if filespec_2 is omitted. If there  are  any 
        differences,  they  will be shown as a hex dump of  file  1, 
        with the differing bytes of file 2 below.

             The  width of the display is automatically set  to  fit 
        the  current screen width, i.e. 16 bytes per line on  an  80 
        column  screen, and 8 bytes per line on a 40 column  screen. 
        If the output is redirected to a file or to the printer, the 
        width defaults to 16 bytes per line.

             If the /P option is given, output pauses at the  bottom 
        of the screen.




Example:

        DIFF XY.COM \BACKUP\XY.COM

XY.COM
\BACKUP\XY.COM
