Eric (& Tom as well),

This works like a charm!  I should have guessed that org-babel would
be able to come to the rescue :-) Many thanks.

Being able to embed such arbitrary programming languages etc is
changing my whole workflow even more than org-mode itself did.  A
typical org file of mine these days seems always to include latex,
shell commands and maxima code, and I can now add gnuplot to this set.
Interestingly, 15 years on, org-mode &co. are accomplishing what the
CMU folk wanted to do with their Andrew project, specifically their
=ez= editor.

It used to be that I hated leaving emacs to do anything; now it's
getting to the point that I hate even leaving org-mode!  I wonder if I
can embed wanderlust within org-mode... ;-)

Thanks again,
eric
