Well, Randal's answer is to make sure a variable consists ONLY of 10 digits -- if that's what you needed, ok. If you want code that sees how many digits there are in a string, you can use tr///: $digit_count = $str =~ tr/0-9//; -- 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.
