in reply to Mileage with safe

Please keep in mind that is not safe. By returning the right values from the safe compartment it's quite possibly to "break out" of it. If I recall correctly it requires that the main program uses the return value; but the Safe compartment wouldn't be much use without returning anything, huh?

Someone with more clue than me can probably provide more insight, but I didn't see this brought up in any of the earlier discussions so I thought I would mention it.
