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?

Thanks to Martin and Eric for showing me how to do this and introducing
Dr Cox's -cond()- to me. Thanks a lot.
