I have now reached the point at which I can start ripping what I have done apart and reconstructing it. In the long run this is going to make extending the application considerably easier, but there are a couple of areas in which some additional considerations must be kept in mind. (Just a hint ... it's a good thing I got into references when I did. <grin>) Much as I've done with everything to this point, I'll start with a fairly simple example and get more complex from there.
