Hmm, thats an interesting link. I studied math through to 5th year at university using sets all the way and never heard the term Euler diagram used, they were always just called Venn diagrams. You learn something new every day! :-) Alan G. _______________________________________________ Tutor maillist - [email protected] http://mail.python.org/mailman/listinfo/tutor
