This is done through UNDOCUMENTED DOS Function 37H This works like this:

	AH=37H
	AL=0	- Querey Current Switch Character
	AL=1	- Set Current Switch Character in DL
	Returns:
	DL	- Current Switch Character

	To Set the char to '-' in assembler (you can do this from Debug too)
	use:

	MOV	AX,3701H
	MOV	DL,2DH
	INT	21H
	RET

Hope this helps....
