Thanks for the oblique compliment, but -cond()- is an official Stata function. My only indirect contribution, some while ago, was to suggest it being generalised so that it could also produce string results. The article referred to by Martin Weiss at http://www.stata-journal.com/sjpdf.html?articlenum=pr0016 was first-authored by David Kantor. However, there remains a problem with your specification. What happens (e.g.) if a1 is 1 AND a3 is 8? Nick n.j.cox@durham.ac.uk Charles Man@CCR Thanks to Martin and Eric for showing me how to do this and introducing Dr Cox's -cond()- to me. Thanks a lot.
