AFAIK, it's COM; without the VFP engine, there's no visibility of the internal VFP representation.

Does the Excel invocation of the method receive the object back, or does it access a parameter it passed in or a COM property to get the array? Excel can't create or use a VFP object on its own (it can instance a COM object that was written in VFP, but can't create or traverse a VFP native class instance on its own.) I don't see how Excel could directly access the content of the VFP object without a COM interface on it.
