Line-by-line is fine. Your Operating System will read from disk in blocks, so stop believing that each line needs a disk access. (unless each line is about the size of a block, but blocks can easily be 2 MB) > I realize the [for-loop] will use more memory, but what's a few megabytes > in today's computers? That can really byte, when there are only a few megabytes left to spare. You don't want a memory fight in your system, because that slows down all processes considerably, because it will start swapping memory blocks to disk for a moment, then read them back in, etc. -- Affijn, Ruud "Gewoon is een tijger." -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] <http://learn.perl.org/> <http://learn.perl.org/first-response>
