Yes, but would you? IMO, using regular expressions to check the value of something creates less readable code. I tend to prefer to first check if I'm really dealing with a number, and then checking the value of it in a good old fashion way; if ( $nr =~ m,^[-+]?\d+$, && $nr < 255 ) { # Match } I don't need to write that regular expression every time, of course, 'cause I've been nice enough to put it in a module so that I only need to write 'is_int($nr)' each time. (And the actual implementation of the is_int() function is heavier; It check if a number really _is_ a number - the above don't, really...) -- Tore Aursand <[EMAIL PROTECTED]> -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
