If your code is properly modularized, displaying the mission menu amounts to a single function call, so jumping around with goto doesn't really buy you anything. I'd conclude that you should refactor before considering a solution with goto.

Indeed. We should also consider the circumstances under which that article was written.

That should be modern enough! Here's a quote from Linus: [I][INDENT]I think goto's are fine, and they are often more readable than large amounts of indentation.
