INT 21 - DOS 3.2+ - GET DOUBLE BYTE CHARACTER SET LEAD-BYTE TABLE

	AX = 6300h
Return: AL = error code
	    00h successful
		DS:SI -> DBCS table (see #01746)
		all other registers except CS:IP and SS:SP destroyed
	    FFh not supported
Notes:	probably identical to AH=63h/AL=00h for DOS 2.25
	the US version of MS-DOS 3.30 treats this as an unused function,
	  setting AL=00h and returning immediately, WITHOUT setting DS:SI;
	  only the Far East versions of MS-DOS 3.2 and 3.3 supported this call
	the US version of DOS 4.0+ accepts this function, but returns an empty
	  list
	IBM DOS 6.1 SYS.COM assumes that CF is set on error
