AS3 does not have references to ints. ints re always passed by value, so you cannot write a method like swap(a, b) to swap them. Just use a temp var. - Gordon

Hi Carlos, Thanks for the note -- I suppose I should have been more clear. I meant, how to swap two variables in one line: it's not about speed but rather clarity. :) Reid
