Looping Program (so that only specific info updates)

So the pastebin is here: http://pastebin.com/mHhdqQp1

What I want to happen is to have all of the real info update every so often (so fuel status, active/not, etc) but I dont want it to be an infinitely scrolling mess, and I want the format to sort of just stay the way it is.

You'll need these for sure:
term.getCursorPos
term.setCursorPos

And using this wouldn't hurt:
term.write
