Detecting a false redstone signal

I am making a program on an advanced computer that will let me use an advanced monitor to control and monitor whether my thermal expansion engines are on. I wrote the code and got no errors, but nothing happens. My code is here http://pastebin.com/YjRUyu27 It would be really nice if someone could help, thanks.

Did it not draw the four asterisks? Did you change the redstone signal input after you started the program?

Actually, it didn't draw the asterisks, I didn't notice that earlier

That would suggest that you might be looking at the wrong monitor, or the monitor may not be large enough.
