Basically, it boiled down to it being a case of making slightly less typing in some cases, and not coming up with any great reasons not to do it. I'm not highly attached to the idea, however. :) I can see not making $start optional, if only to add slightly more consistency to the interface (which is lost again by $length being optional, but what the hell ;) ). So if there are reasons not to, that's cool. Torben
