 :Your program will always return *something*.  If you don't do it

 :default.  Since many other djgpp programs check this code ("make" is

 :For example, if you called your program in a Makefile and it returned
 :some non-zero garbage, make would stop at that point, thinking it was
 :an error.


Are we talking about the exit(something) value, or is this another
return mechanism entirely?
