                                                         Compatibility: 5.0+ 
 Expects: AX    b704H
 Returns: ES:DI Address of the ASCIIZ "data search path"
    Info: This returns the address of the APPEND search path.  It is in a
          form similar to the DOS command search path (maintained by the
          Path command).

          The APPEND path is a series of directory names, separated by
          semi-colons (;) and ending with a byte of 00H; for instance:


    Note: A quick check shows that this returns the address of a buffer
          that appears be at least 128 bytes long.  Thus, it may be
          possible to add directories to the append path by modifying this
