${ltrs} is a variable that you declared earlier. It denotes \w, which is
a reg expression for any word character (alpha-numeric). The ${gunk} is
uses to represent any not understood character which was declared two
lines before it.I assume that $any is used thereafter someplace to represent a regular expression consisting of alpha-numerics, punctuation and characters that are in the gunk set. -- Nestor -----Original Message----- From: Pam Derks [mailto:[EMAIL PROTECTED]] Sent: Thursday, January 03, 2002 6:17 PM To: [EMAIL PROTECTED] Subject: newbie question I've been trying to understand program 6.21 in the Perl Cookbook, which changes URLs to html links here's a snippet: #!/usr/bin/perl $urls = '{http|telnet|gopher|file|wais|ftp'); $ltrs = '\w'; $gunk = '/#~:.?+=&%!\-'; $punc = '.:?@\-'; $any = "${ltrs}${gunk}${punc}"; I understand what $any is, but what exactly is ${ltrs} or ${gunk} ?? is this an anonymous hash thanks for any help, Pam -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
