Many, many thanks Raphael!  Since you put me straight on this I have
accomplished more in the last two hours than the last two weeks!  All
my code has suddenly started working as I'd hoped.

I think I like ANTLRWorks well enough when it works to forgive this
incident, but really, the interpreter seems more of a booby-trap than
a feature just now. It should pop up a warning when you try to use it.
