I absolutely agree that the problem is connected to binary representations of integers as you suggest. The problem -- given my needs -- with your suggested approach is in "use your favo[u*]rite binary conversion recipe". I want my code to be stand alone and I feel fairly safe in asserting that if I implemented your suggestion in a self-contained chunk of code, I'd end up with something more complex than the code I originally posted. In effect, my original code exploited the same principle, without actually going through the binary representation. I am of course open to the possibility that my suspicion is ill-grounded ;-) But, thanks! Best, Brian vdB [*] I'm Canadian, eh! ;-) _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
