Thanks Michael. It worked and I learned something. Not sure I understand it
fully, but the light went on. I need to have a better understanding of OO.
"Objects", "instances", "methods" are still a mystery to me. It's kinda like
knowing how to drive, but not knowing how an internal combustion engine
works. I want to know more about the engine.
Thanks again.
