*> *> Normative figures perhaps. Normative equations definitely. Scott, How about Sections 4.2.3.3 and 4.2.3.4 of RFC 1122 (1889), for examples of readable equations in ASCII?

People who REALLY use equations generally prefer LaTeX. Bob Braden _______________________________________________ Ietf@xxxxxxxx https://www1.ietf.org/mailman/listinfo/ietf
