⎕PARENT Base (parent) class

Implemented for Internal and External classes. Not implemented for System classes.

Syntax:

    classref ← objref.⎕PARENT
    classref ← classref.⎕PARENT
    classref ← ⎕PARENT           (Within user-defined method, same as ⎕THIS.⎕PARENT)

The niladic system method ⎕PARENT returns a reference to the parent class of either an object, or a class. The result is always a class reference, or the Null object if there is no parent. It is a synonym for ⎕BASE.
