Well, the "problem" is that I'm not *really* a PC C programmer (I just play
one at night).  I thought about using malloc (if it's similar to the
pdp-11 unix version) but this would take some additional digging on my
part.  I'd love to see some code to do this, (Hint, hint! ;-)

That would be my first suspicion, too.
