----------------------  DISKCOPY - External DOS Command  -----------------------

DISKCOPY copies one diskette's entire contents to another diskette.

FORMAT:   DISKCOPY [d1:[d2:]][/1]

REMARKS:

   d1: - the drive of the diskette to be copied, "source."  If omitted, the
         default drive is assumed.
   d2: - the drive of the diskette to be copied to, "target."  If omitted, the
         default drive is assumed.
   /1  - specifies that only the first side of the diskette is to be copied,
         even if the diskette is double-sided.

   If you omit d1, you must not specify d2.  DISKCOPY will allow this, but it
   will interpret the d2 drive to be the d1 drive.

   A single-drive copy is performed if both d1 and d2 are omitted, or if d2 is
   omitted and d1 is specified as the default drive.

   Any information on the target diskette that existed before the DISKCOPY is
   performed will be replaced with new information.

   You will be prompted to enter the source and target diskettes in the
   appropriate drives.

   DISKCOPY works for diskettes only.  If a fixed disk letter is specified, an
   error message is displayed and processing ends.

   When the copy is complete you are prompted:

          Copy another(Y/N)?

          Enter Y to perform another DISKCOPY, enter N to end.

   If the target diskette has not been formatted, DISKCOPY will format it.

   If a disk error occurs on either diskette, the diskette drive, side and track
   of the error will be displayed and DISKCOPY will continue.  In this case the
   target diskette may not be usable.  If an error occurs, reissue the DISKCOPY
   command and then perform a DISKCOMP to ensure that the information was copied
   correctly.


NOTE:  After performing a DISKCOPY, you may want to use DISKCOMP (compare
   diskettes) to ensure the target diskette is identical to the source.


WARNING:  Any information on the target diskette that existed before the
   DISKCOPY is performed will be replaced with new information.


EXAMPLES:

Copy the entire contents of one diskette to another.  The source drive is A and
the target drive is B:

          DISKCOPY A: B:


Perform a single-drive DISKCOPY using the default drive:

          DISKCOPY        (you will be prompted to insert the diskettes)
