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
