Where is Xcode 3.0's output window?

I'm learning Xcode off a slightly older (10.2) book that deals with Project Builder. I've been using Xcode for ansi C for a while, but I can't find the output window that appears when you Build & Run an app. I am launching my apps from the commandline, but of course that doesn't help me if I want to set breakpoints or something. Where is the program output window that should appear when I build & run. Do I have it hidden or something ? Why can't I find it ?
