Thankfully, all integers are positive! Must have been having a blonde moment, 'cos as soon as I read your answer it was "of course that works". Not concerned about 'fast' as I hardly think with DB and disk I/O I'm going to worry about bit- shifting... Much appreciated John, Jon. -- http://mail.python.org/mailman/listinfo/python-list
