Aha! Apparently I either missed or didn't quite understand the nature of
the problem (perhaps a function of late night e-mail reading :). This
makes perfect sense now and I think it might help with the problems I'm
having. Exactly the sort of info I was looking for.
Just to make sure I understand, if I do:
ofstream * fout;
fout = new ofstream;
fout->open("hello.out");
... etc ...
fout->close();
delete fout;
it should work, right?

Makes me wonder too, but evidently there seems to be a lot more focus on
VPASM and such.... oh well, mark it up to growing pains I guess.

Very, very bad! Looks like I'll have to mod a bunch of code to work
around this. :-(
Thanks for the quick and informative reply!
