Setting window width in Xcode

Question

Probably a very simple question. I would like to set the width of the code editor in Xcode 4 to 80 characters. Where would I go to do this? Alternatively, if I can draw a vertical line displaying the character 80, that would be fine too.

Thanks.

In Xcode 4: Xcode menu → Settings → text editing tab → check page manual in the column :.
