Michael,

I generally stay out of those religious war threads, I don't have the time to waste on them. I wanted to make sure that quote wasn't coming out of some official VFP documentation.

VFP is more like Smalltalk than it is C++, much more happens at runtime, variables can change type at runtime in VFP, they can not in C++.

Subclassing doesn't really occur at runtime though. The inheritance hierarchy is defined at compile time. VFP is looser though WRT changes to classes higher up the class tree. If I have ClassC derived from ClassB which is derived from ClassA, and I make a change to ClassA, I do not have to recompile ClassB or ClassC to see the change take effect when I instantiate either a ClassB or ClassC.
