That's true, but for clarity I would stick with the first. I also wouldn't be surprised if the \S construction is slower to match, given that it has a larger set of things to look at. (On the other hand, perl might just turn "unless /\S/" into "if /\s*/". That seems like an obvious optimization. I wonder if there is an RE algebra?) -- Offer no violence. http://www.hacksaw.org -- http://www.privatecircus.com -- KB1FVD -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
