sounds like you want the substr() function. perldoc -f substr $last_5_chars = substr($string, -5); The cool thing about that is you don't need to worry about the string length -- whether it be 7 or 100 characters, you'll get the last five. -- 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.
