If you don't know where to put code which does something, or you have a hunch but can't explain to yourself, then just don't. Sit a while and think it over, or call an Auntie Emma.

If the code isn't part of that, then it doesn't belong in this class. Then it's "so what does this code do?", and the answer to that helps me see where it will go. Maybe it's a worm from a can I haven't opened yet - if it is, then design a new class. Doing so usually rings some bells and few other stray pieces of code fall naturally into this new class.

It's a shame that good OOP practices haven't been pushed more hard in the VFP community. Most code samples you got from FoxPro were really not worrying about good design.
