direwolf20's currant base code re-write help

Hello. If you have watched direwolf20's currant video (Christmas 2012), You are aware of the code he has built for the base. I would like some sort of help creating a version of that. My problem is that everytime i enter a new code, the old one goes away. I am new at this and would like some help. thanks and Happy holidays.

heree is the startup code: http://pastebin.com/ZHhR1f9V

Then I put the number in. going into a different programs.
the code I use is

os.loadIAPI("output")
output.setside("back") –The cable is in the back.
output.set("color", true or false")
shell.run("startup")

I know this isn't right. I just dont know how to make it work.

p.s. this was V.4 of trying this.

Type 'edit filename' into a computer. Then type your code. Hit control, press s, press control, press e. Then just type the file's name into the computer.
