Cool 'nall ++, but the real code does somewhat more than just printing a few numbers. (And the numbers aren't constant either.) The reason for refactoring is because I now want to do more than just next in that branch of the code. With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday' Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error. "Science is about questioning the status quo. Questioning authority". In the absence of evidence, opinion is indistinguishable from prejudice.	[reply]

What? That was contrived? Next I was going to post `say for 1,5,7` and call it a day. :-) I mean... understood. More of a fun reminder to never stop looking for ways to calculate rather than iterate, regardless of the problem.	[reply] [d/l]
