This begs the question of technique.
If I have several DBs, each represented by a form, so they need to be open
when their form is in use, and then all need to be open during other
operations, should I open 'em all up (about four, I think) on launch, and
close 'em on AppStop or should I open each one when it's form is on the
screen, then close it, opening all of them only when I _need_ all of them.
On a disk based machine, the answer is obvious, but on our memory based
machines, where heap is at a premium, what is the best procedure.
Thanks,
