Hi all Let's say that I have the following situation:
GreatGrandParent -> GrandParent -> Parent -> Class
In Class I want to bypass the code in Parent but call the code in either GrandParent OR GreatGrandParent.
Is this possible and, if so, how? Many thanks

Hmmm...See :: Scope Resolution Operator in VFP help. That references calling the PARENT but not sure how you'd leapfrog back 2+ levels. I'm sure the Foxperts here will answer shortly.

Sounds a little bit like "bad design", but if life demands such constructs....
You can always get the code from the upmost level by using the "QuatroDot" operator :: like class::MyMethod()
If you would need one in between, then you need to do some clever IF branching in the beginning of each level's code by providing a parameter when calling the method:
PROC MyMethod LPARAMETER lSkipIt IF lSkipIt RETURN DODEFAULT() ENDIF && regular code goes here
wOOdy

Many thanks to everybody who has replied - I had come across the :: operator many moons ago but had forgotten about it. Paul Newton

I would agree that it seems kludgey. Worked for a "genius" last gig and he used it and it was amazing to see it in action operate easily but my spidey sense said "yeah, no...I don't like it."

Same. Code smell.
