Thanks Ed. I've simulated multiple inheritance and didn't even know it.

Take care.

>Multiple inheritance means that subclass inherits PEMS from two or more parent classes, instead of one as it's done in VFP. BTW, it still can be simulated in VFP by combining two classes into one container class and then subclassing the latter.

The procedure to use is determined at run time by the class of the object. For example, related objects might both have Draw methods. A procedure, passed such an object as a parameter, can call the Draw method without needing to know what type of object the parameter is.

>>>Oh, heh. I guess I didn't think to check the help because I had the idea that polymorphism was multiple inheritance, which vfp doesn't support. That in turn made me think that the Corel employee was mistaken about his terms, which I guess he wasn't.
