Int 2F Fn B701  U - Append V3.21 Only - Get Append Path                    [-]

   AX = B701h

Return: ES:DI -> active APPEND path

Notes: the only version of APPEND known to support this call is the APPEND
     shipped with Microtek MS-DOS 3.21; MS-DOS 3.30-6.00 APPEND displays
     "Incorrect APPEND Version" and aborts the caller
   use AX=B704h first, and only call this function if that one is not
     supported
