Thanks Michael and Jörg,
I agree that large modules are to be avoided and factoring a module is
better than just relaxing limits, especially without understanding the
consequences. Having bumped up against the limit (and then refactored my
code) I wanted to know the nature of that limit.
Much appreciated,
Chuck
