>>There's no AddObject() function in VFP. I guess you're refering to NewObject() and AddObject() methods. If that the case than NewObject() method is very similar to the NewObject() function and AddObject() method to the CreateObject() function.

The .AddObject() and CreateObject() rely on SET CLASSLIB and SET PROCEDURE (non-visual classes) to find a class to instantiate. The NewObject()/.NewObject() allow to specify a class library/.FXP as parameter.
