>You need to take some care here, especially if you invoke methods of the object you've passed into your procedure. It's possible that invoking a method of the object might invoke another instance of the same function; at a minimum, I'd aggressively make sure that I used an LPARAMETERS statement to force LOCAL scoping of the parameters, and I'd explicitly declare all variables as LOCAL to avoid possible side-effects where VFP creates an undeclared variable with a PRIVATE scope the first time, but uses the existing visible PRIVATE instance on subsequent calls.

Thanks for the heads-up Ed, I'll take that advice. Although, at this time, I'm only referencing properties of the form... who knows what the future holds ;)
