This is the ZCL Wish List
		---- -- --- --- ---- ----

	/BD has too little range checking.

	/AD should be using the BLKVAL type 
		double word input while /BD does not need it
		and perhaps double word for /OF also.

	/IS shows too much memory address space.
		Make it only one and the conversion only.
		Implement a /DU switch to dump like OPEN does.

	Implement a /BH like algorithm of ZBL to find and seek
		like a blood-hound to locate the exact area in the
		TTDRV code for the literal patch.
		This requires mapping the TTDRV code by using the
		PCB's and using the .STB for the TTYHV module address.

	Only allow the POKE if the exact location of the literal
		to patch is certainly known by a massive compare of
		the code in the TTYHV module around SETLIN symbol
		especially 70$: and all between conditional compiling
		directives to make the compare work universally.

	Make ZCL do the actual SET /SPEED=TTnn: with the set multiple
		characteristics QIO to the TTDRV using the following
		syntax to ZCL ...  MCR>ZCL /BD:7=TTnn:
