Many thanks for your reply. I still do not seem to be able to get my
head around the TRY syntax but I will give it a try anyway ! Are you
suggesting that the CATCH clause doesn't actually have to contain
anything ? In this case I don't need to trap an error and in the past
might have saved ON("ERROR"), issued an ON ERROR * and restored the ON
ERROR.
The examples I have seen for TRY... all seem a bit contrived rather than
demonstrating "real-life" scenarios - also I need to get my head around
how it works with and without an (ON ERROR type) handler in place. If
anybody has any "reading suggestions" I will gladly do some homework
Tx again
