You are right there Helen. Now, it works for me the way I need it. :)

Try as an exercise to debug your procedure in 'IBExpert' and you will
get stuck.

The "IBExpert's" after all do not seem to be as much experts as they
would like to be. At least they should not attempt to charge
professional licensing fees for an immature product!

Even worse. They better let go of the very alienating idea to force the
user to have software bound to a particular machine! In a large
corporate machines change and/or move but not necessarily the person(s)
that still do(es) the same job. Database design that is.

I am trailing 'IBExpert' since a few days. It's an interesting tool yet
it still has miles to go.
