I think it's saying that just like: $a += 2; is the same as: $a = $a + 2; similarly: $a ||= 3; is the same as: $a = $a || 3; ... implying if $a is false, $a gets set to 3, otherwise it stays at whatever it was. - B -- To unsubscribe, e-mail: beginners-unsubscr...@perl.org For additional commands, e-mail: beginners-h...@perl.org http://learn.perl.org/
