The imported text files don't normally have public or even private
variables, although they could have.
I think I will go with may latest reply to Peter T's post.

In fact checking all the variables doesn't even catch everything as there
could be wrongly
named functions and/or subs.

This is the core of the problem and I don't think it has a satisfactory
solution. Unfortunately you are working in the dark.

I wonder if there might be a way of importing not just the sub but also
all
globally declared variables. That might alleviate the problem.
