I'm sensing some fundamental confusion here. There are several common
meanings for the term "parent" of an object.
The most fundamental, and the one most posts are addressing, is that
of a parent of a class being one of its superclasses in an inheritance
relationship. That's the type of parent to which super() applies.
I'm not sure if Visual Foxpro supports true inheritance; if it
doesn't, the concept probably won't be clear to you.
The meaning of "parent" which is aided by keeping a linked list is
when parent refers to an object (not a class) in some form of
hierarchy of objects, such as a tree.
I've also seen "parent" used in visual environments to refer to the
container of a control. In this case "parent" refers to an object
which may be a totally different class, and the relationship is one
where the container "owns" the control and constrains its behavior.
So what sort of "parent" are you talking about here?
