--eof --wtf? what is this?

--[[
see http://computercraft.info/wiki/OS_(API) for details on how to use the events.
]]

-- since all you want is the "char" event, make this simple on yourself and use
_, key = os.pullEvent("char")
-- since you are targeting char event you don't need that event variable and you can toss it with _
-- also call your variables meaningful names so it is easier to debug your program
-- longer variable names and function names help you create what is called
-- self-documenting code, combined with comments people will be to help you better and you can
-- always return and pick up where you left off.

-- instead of
-- e,p== os.pullEvent() = - This line

-- see now here we run into that part where you really need to understand code
-- because you see the input
-- if e == "char" then
--[[ and this line have been giving me problems :(/>/>, it says I need a = sign some where in here and I tried putting it everywhere and it still didn't fix it D:
]]
-- that's because it was complaining about your hordes of other bugs but you didn't realize it.
   -- if you use my pullEvent you don't need this "if e ==" thing
   if key == "1" then
	  -- so you should be testing against key if you use my example, even so all of the below
	  -- is just for reactor 1, you'll have to repeat the tests for each of the options in your menu
	 wipeScreen()
	 print("Loading Mainframe...")
	 sleep(3) -- even one second is a long time try smaller values
	 print()
	 print("Loading Subsystems...")
	 sleep(2) -- same here
	 print()
	 print("Starting Reactor quad core 1...")
	 sleep(2) -- weee, i'm on a roller coaster!
	 redstone.setBundledOutput("back", 1)
	 sleep(2) -- why? what's the precedent for these?
	 redstone.setBundledOutput("back", 0)
	 print()
	 print(" Reactor quad core 2 Successfully Started")
-- really? how do you know? I don't see you reading it's output.
end

-- I suggest taking all the stuff for option 1 and jamming it into a function say maybe call it function startReactor()
-- and then pass the reactor number to it, that way you can reuse the code without making your program
-- unnecessarily long.
-- btw, the end above was for the second if not the first, the first if was missing an end and also would've thrown you an error
-- but since you don't need the first if you can leave it out and not worry about the second end
-- you need to study up on if-then-elseif-else-end blocks.
--return --unnecessary, only useful inside of lua chunks.

-- your challenge btw is to learn from my own noobish code, rip out all the comments and progress a little further.
-- put your own comments in all over the place so you will know what you are doing.

-- implicitly localize and initialize variables that outside of functions
local password, key = "",""

-- setup your functions that contain code you wish to reuse
function startReactor(type,unit,bundleColor)
  -- type will be either "breeder" or "quad core"
  -- unit is its unit designation number
