  SEMANTICS
	The CD program will mount one or more Sub_Device files,  define a
	logical name pointing to each,  and connect  (assign DK:)  to the
	first one specified.  The default superior device is SY:, and the
	default Sub-Device file type is .DSK.  The logical name chosen to
	point to a  Sub-Device  file is always the first 3 letters of its
	filename.  The handler used is LD.SYS.  A maximum of 8 Sub-Device
	file  specifications  (separated  by commas  with  no intervening
	spaces or tabs) may be specified in any one command.

	Note:  The default superior device will be the most recent device
	       specified; initially this is "SY:".

	The command line is read with GTLIN so input may come from either
	the user's terminal or a command file.  The following environment
	is required:

	1) SY: contains at least 1 free block and is Write-Enabled.
	2) The file SY:CDCMD.COM is not protected or is Non-existent.

	Valid responses to the "Connect to Sub-Device:" prompt are:

	.R CD
	Connect to Sub-Device: File1 [,File2] [,File3] [, ... ,File8]
	(with no embedded spaces or tabs) where "File%" may be any of the
	following:

		Name		- to connect to SY:Name.DSK
		Name.Ext	- to connect to SY:Name.Ext
		DEV:Name	- to connect to DEV:Name.DSK
		DEV:Name.Ext	- to connect to DEV:Name.Ext
		DEV:		- to assign DEV: DK:
		none		- to assign SY:  DK:
