If I am asked how to convert if ($x eq 'y' or $x eq 'z') { ... } to a regex, I will give the correct answer: if ($x =~ /^[yz]\z/) { ... } Using $ changes the range of accepted answers. That is why I use \z instead of $. If the question asked was something like "how can I see if the user entered 'y' or 'z' as input?" I would probably use $ because there is no way of determining whether the person asking has chomp()ed or not. -- Jeff "japhy" Pinyan [EMAIL PROTECTED] http://www.pobox.com/~japhy/ RPI Acacia brother #734 http://www.perlmonks.org/ http://www.cpan.org/ ** Look for "Regular Expressions in Perl" published by Manning, in 2002 ** <stu> what does y/// stand for? <tenderpuss> why, yansliterate of course.
