Malcolm stated that when he runs his script in an interactive shell, the
variables he is interested in are available.  I made the assumption,
perhaps unwarranted, that he knows what he is doing and that he was
sourcing the script.

I did make a mistake in my suggestion, which in fact does work, but
needs more, as in:

   bash -c "source script-name; other_actions"

where 'other_actions' would presumably make use of the information in
the "global" bash environment.
