Good question. Perl 6 is fixing this by adding a 'trim' operator. The code I use is for ($var) { s/\A\s+//; s/\s+\z/ } >2. what's the standard module or method to generate a random string, for >example >the string will be used as part of url. If you want to use the string in a URL then it cannot be truly random, because not every character can appear in a URL. Why not just generate a random number and use that as the string? -- Ed Avis <e...@waniasset.com> -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
