----------------------  DISKCOMP - External DOS Command  -----------------------

DISKCOMP compares the entire contents of two diskettes.  DISKCOMP is useful
   after a DISKCOPY operation to ensure that the diskettes are identical.

FORMAT:   DISKCOMP [d1:[d2:]][/1][/8]

REMARKS:

   d1: - the drive letter of the first diskette.  If omitted, the default drive
         is assumed.
   d2: - the drive letter of the second diskette.  If omitted, the default drive
         is assumed.
   /1  - performs a comparison of the first side of the diskettes only, even if
         the diskette are double-sided.
   /8  - performs an eight sector per track comparison, even if the first
         diskette contains nine sectors per track.

   If you omit d1: and specify d2:, DISKCOMP will interpret d2: as the first
   diskette and assume the second diskette is in the default drive.

   If the drive letters, d1: and d2: are identical, a single drive comparison
   will be done.  You will be prompted to insert the diskettes.

   If you omit both d1: and d2:, a single-drive comparison is done on the
   default drive.

   If the diskettes are not identical, a message indicating the track number
   (0-39) and the side (0 or 1) of the mismatch will be displayed.

   If the diskettes are identical, the message "Diskettes compare OK" will be
   displayed.

   After the comparison, you will be prompted:

          Compare more diskettes (Y/N)?

          Enter Y to compare more diskettes, or N to end the command.

   DISKCOMP compares diskettes only.  If a fixed drive letter is specified, an
   error message will be given.


EXAMPLES:

Compare the diskette in drive A with the diskette in drive B:

          DISKCOMP A: B:


Perform a single-drive diskette comparison on the default drive:

          DISKCOMP       (you will then be prompted to insert diskettes)
