My earlier description wasn't very clear. I want to be able to
create a system with the following behavior:

A handler (let's call it Foo) in card A gets executed (called
by a button script or whatever). During its execution, Foo
does a "go card B" AND PASSES CONTROL BACK TO HYPERCARD. The
user is now interacting with card B (and Hypercard). Some user
event causes a "Finished" handler in card B to be executed and
control is returned to Foo (the handler in card A). Note that
just doing a send to Foo won't do the trick. Foo needs to
start back up where it left off. In other words, it needs to
be able to call Hypercard as a function (or by passing a
message or whatever) and then continue with what it was doing.
