Danny Cox asks, in essence, how to avoid having to keep two sets of
code "in sync" when you've got external variables defined in one
place but referenced in lots of others.

Sorry, Danny, but I can't resist:  my favorite way of dealing with
the problem is to avoid external variables.  Passing information as
parameters and returned values is a much cleaner way of communicating
between different modules.  I know, this doesn't help much if you
have to contend with existing code that's rife with external variables...
