in reply to Re^2: using passed parent object reference to get at attributes
in thread using passed parent object reference to get at attributes

@ISA is something I knew nothing about so thanks for raising it as a possibility...I see it's "Each package contains a special array called @ISA . The @ISA array contains a list of that class's parent classes, if any. This array is examined when Perl does method resolution, which we will cover later. " Thank you for the education!
