Bill,
Perhaps a better analogy would be that I need to know how to build a
formula one vehicle, not drive one.
Your suggestion wasn't rejected out of hand. I did download the trial
version, tested it and then determined that I can't use a commercially
available package, but really need to roll my own. If I had known that
at the outset, I would have stated this, but this is a discovery
process for me as well. No need to get your feathers fluffed over it
though.
