My apologies, I didn't intend to annoy anyone in this forum. All I wanted was
indeed some general guidlines on how to solve the problem. The posting was
indeed too long with too much info in it, but when I started the thread it was
extremely difficult to break it into smaller pieces. However my goal was
accomplished. Thanks to your suggestions, I am now well on the way to solve it.

Again my apologies if i annoyed anyone, this was certainly not my intention.
