Arrays start at 0. Thus, the first element of an array is $array[0]. Line numbers (as far as human think of them) start at 1. The first line is considered line 1. Therefore, humans are thinking +1 from what computers are thinking. To correct this, you subtract 1 from what the human enters, and the computer does the right thing. -- Jeff "japhy" Pinyan [EMAIL PROTECTED] http://www.pobox.com/~japhy/ RPI Acacia brother #734 http://www.perlmonks.org/ http://www.cpan.org/ <stu> what does y/// stand for? <tenderpuss> why, yansliterate of course.
