Int 21/AH=47h

DOS 2+ - CWD - GET CURRENT DIRECTORY

AH = 47h
DL = drive number (00h = default, 01h = A:, etc)
DS:SI -> 64-byte buffer for ASCIZ pathname

Return:
CF clear if successful
AX = 0100h (undocumented)
CF set on error
AX = error code (0Fh) (see #01680 at AH=59h/BX=0000h)

Notes: The returned path does not include a drive or the initial backslash. Many Microsoft products for Windows rely on AX being 0100h on success. Under the FlashTek X-32 DOS extender, the buffer pointer is in DS:ESI
