>Difficult to do, since VFP doesn't support interface inheritance.

Craig - help me here - As far as I understand it - "interface" - at least as far as VFP is concerned and in practical terms - is the pool of public methods and properties. Since these methods/props are available (inherited) when I subclass - how is that not "interface inheritance"? If not - how does interface inheritance differ from the behavior I mentioned? In other words - if VFP had interface inheritance - what would it allow me to do that I can't now?

I'm not denying what you are saying, I just want to make sure I understand.

Thanks!
