I wonder, how you implement 
INT 21 - 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 #1020 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 


for directory size >= 64
