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
