Alvin,

I appreciate the time and effort of your response and thank you, but I have
the thing working just fine and using the debugger was part of how I managed
that. With this application, I have the "what", I am attempting to
understand the "why". Not harping on you, but sometimes, I really am after
the answer to the question I asked. I just have to leave it up to those out
here to read the question as I wrote it.
