Hi Rod,

thank you for looking at this. Here is my assembler code (TASM) which
prints out the environment fine in a Windows XP DOS BOX:

            .MODEL SMALL
stack 100h
            .CODE
START:

                     mov  cx,3600
		     mov  ax,word ptr ds:[2Ch]
		     mov  ds,ax
		     xor  dx,dx    ;point DS:DX to environment
		     mov  bx,01h
		     mov  ah,40h
		     int  21h

                    mov ax,4C00h
                    int 21h

.data
		     END  START

I would be fine if I could do that in DJGPP, retrieving the absolute
path from that does not seem to be very difficult then.

Maybe DJGPP frees the environment block of the running program
somehow.
