[Javascript] <OBJECT> dereferencing

Dear Tom:
Some of my other applications use frames, so yes, I am familiar with what
they can do. However, frames are "fixed" to the window space [yes, there are
ways of dynamicly moving them about, but they are somewhat pathological], and
I want things that close-up when they are deleted, can be scrolled as sets,
and generally manipulated on a "rubber" background -- none of which are easy
(or possible) with the conventional frame architecture.
Basicly, I need to know how to reference back to the parent object that
contains the <OBJECT> declaration that contains the code snippet, as seen
from the internal code snippet. The rest I can figure out using the tools I
have available to me.
