    * To use this program you must have the DiskDisk utiltiy
from MISOSYS.

   This is a little  utilty to use with the DiskDisk utility
from MISOSYS that allows us to emulate the MS-DOS CD command.
I wanted to be able to change  DiskDisks as easy as I change
subdirectories on MS-DOS.

    The program is currently written for LS-DOS/TRSDOS 6.  I
do have  DiskDisk  for  LDOS 5 and will probably be doing a 
version for that environment.

    While this program emulates the CD command there are some
differences  that  need  to be kept in mind.  First, you must
have at least one  DiskDisk  that has been created by DDFORM.
CDD  will  not  create a new  DiskDisk  file.  Secondly,  CDD
assumes that you will be using "drive 2" (:2) as the DiskDisk
drive.  This can be changed as follows:

	If you have access to EDAS or some similar editor/
	assembler, change the 2 at the CMD$ label to the 
	drive number you want.

	If you don't have access to the editor/assembler,
	apply the following patch line to CDD/CMD.

		PATCH CDD/CMD (D00,93="dn":F00,93="2")

	   replacing the "dn" with the drive number you want.


SYNTAX:

		CDD [filename]

	if a filename is not given, CDD will close any active
	DiskDisk assigned as drive 2.

	if a drive number is given, CDD will close any active
	DiskDisk assigned as drive 2 and attempt to open a new
	drive 2 using "filename" as the DiskDisk file.


REVISON HISTORY:

1.0.0 - 10/30/93

	This was the first public release of this program.
