Hi Paul!

I decided not to answer this one, but that was quite a few hours ago and
no-one has answered you yet. The one thing that struck me was that this
seemed to be written by someone accustomed to desktop databases rather than
client/server. Generally, in client/server you should only get records of
interest, not the full table or view. I.e. it is OK to grab 5000 records if
they're all interesting - e.g. for some reports, but for showing in a grid
I would say most people rarely are interested in more than 10 records at a

So, add a where clause to your query, and use that rather than locate.
Also, try out the searching capabilities of IBO, I haven't used them much,
but they are very simple to use.
