Int 21/AX=6300h

DOS 2.25 only - GET LEAD BYTE TABLE ADDRESS

AX = 6300h

Return:
CF clear if successful
DS:SI -> lead byte table (see #01746)
CF set on error
AX = error code (01h) (see #01680 at AH=59h/BX=0000h)

Notes: Does not preserve any registers other than SS:SP. The US version of MS-DOS 3.30 treats this as an unused function, setting AL=00h and returning immediately
