In normal case, when we want to swap 2 var, , say $x and $y, we do in this way :
$z = $x; $x = $y; $y = $z; # Swapped today, I suddenly found a code like this : $x ^= $y ; $y ^= $x ; $x ^= $y; # Swapped It works !! but how that works ? Could anybody tell me ? Rgds, Connie -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
