Thanks Simon!

That's a lot more information than I had when I started down this road!

I may contact IBM about this, but since I need a solution to a problem
immediately, it won't be anytime soon. I'll be spending my time now looking
for an alternate way of doing what I need to do.

Thanks for the info!
