I use main-level programs this way, too. But I see plenty
of people who use them (misuse them?) almost exclusively
and I think that is a big mistake, since it almost always
leads to unanticipated errors once you get more than about
10 lines of code in the darn things.
I certainly didn't mean to pick on you, but I'm almost
certain that if you can't run a program twice and get
the same result, it is programmer error in a main program. ;-)
Cheers,
David
