Your method of communication is as lucid as ever (or perhaps even
moreso).  Is it possible to move over gradually and realize some
benefit along the way instead of beginning the rewrite process and
hoping I'm one day able to flip the big switch?  Instead of getting
IC5 stuff to run on IC6, can parts of IC6 be used with IC5?  Or
perhaps more practically, are there best practices for rewriting ITL
in Perl so that it still runs on IC5 but is as easy as possible to
port to IC6?
