Some good suggestions from you and John.

I'm not planning on implementing any such scheme today. Was more curious if anybody had tried it. I'd love to try some scheme later. (Of course, finding the time is always the issue <g>)

With the wrapper, I could implement the Left() method to call LEFTC and not touch my code. I could change all my _VFP.MessageBox(...) calls to actually be implemented as a MsgSvc() call or whatever.
