I've got Release 4 of Objectworks\Smalltalk from ParcPlace. The
application I'm trying to load is ThingLabII, a university research
project from University of Washington. ThingLabII was compiled 
under Smalltalk 80 2.5.

Objectworks included a backwards-compatibility extension which I've
loaded, and I've renamed classes as seem feasible.

There is a class in ThingLabII called ParseNode, which I can't find
in ObjectWorks.

The question(s): does this class exist?
		 have I left out any obvious steps?
		 anyone using ThingLabII?

Any help is appreciated!
