I mean I know this depends on the available memory, but presumably a few kilobytes or even megabytes won't cause too much of a strain? <snip> > Since you're using <> in a scalar context here it will read > individual lines into the $_ variable.

How about if you want to pass lines 5 to 25 into an array, what's the best way to do that? Or what I'm really after, how to pass everything between two strings into an array? Excuse me asking that on a beginners list, I just suspect there's some built in function I've missed that will allow me to do that in a couple of lines.
