Uhh, that's still imperative. There is a chronological boundary here: prior to that statement's execution, x and y have certain values, and after it, they have the same values but the other way around. When you're manipulating algebraic statements, moving down the page doesn't correspond to any sort of time change, which is why "x = x + 1" has no solutions. Please explain to me how "x,y = y,x" is materially different from "x = x + 1" in that the latter is, in your words, an abomination, but you say the former doesn't have the same problem. ChrisA
