Fix: for($left = 0; $left < $#hold; $left++) { if($hold$left == $hold$left+1) { return 0; } } reply d/l code Re: problem with perl "for" loop by Happy-the-monk on Mar 11, 2004 at 18:09 GMT+5 It's a warning, not an error. $hold$left+1 will eventually become bigger than the index of the array's last element.
