I agree that it is awfully big, and it will be getting bigger. On the
other hand, searching a single document is a lot easier than searching
a hyperlinked glob of documents. I am thinking about the various
possibilities - I'll let you know what I decide to do!

Another reader has already posted the solution here. Remeber that the
things you push into the Funcall are the arguments just as they would
appear in a Jess function call - and undefinstance doesn't need the
class name as an argument.

I generally leave out things that can be trivially written by the
user, to keep Jess's size down. In this case, you can write a class
called JessUtilities, or some such, with methods like
void undefinstance (Rete engine, Object o)
{
Funcall f3 = new Funcall("undefinstance", engine);
f3.add(new Value("tank", RU.ATOM));
f3.add(new Value(o, RU.EXTERNAL_ADDRESS));
f3.simpleExecute(f3, engine.globalContext());
}
