Yeah, but, remember that calling delvar *also* erases the main
program you have running. Just a quirk I ran into playing around
with it a couple of days ago myself.

This may or may not be a problem. In any case, putting delvar
in a program seems to be a pretty bad idea, as the program erases
itself...

Or, is there a way around that? Anybody?
