Random numbers at end of failed script - ComputerCraft Forums (archive)

Posted 25 July 2012 - 06:46 PM
I have a script with a create account function and when i select that one option i get a blank screen and a number at the end. Can any one help?

Code:

function os.pullEvent()
local cEvent, p1, p2, p3, p4, p5 = os.pullEventRaw()
  if cEvent == "terminate" then
  end
return cEvent, p1, p2, p3, p4, p5
end
function getCenterX(sText)
local nWidth = term.getSize()
local x = math.floor(nWidth / 2) - math.floor(string.len(sText) / 2)
return x
end
function getCenterY()
local nWidth, nHeight = term.getSize()
local y = math.floor(nHeight / 2)
return y
end
function getRight(sText)
local nWidth = term.getSize()
local x = nWidth - string.len(sText)
return x + 1
end
function runMenu(mChoices, sMenuTitle)
local nSelection = 0
local bLoop = true

while bLoop do
  term.clear()
  term.setCursorPos(1, 1)
  print(sMenuTitle)
  print()

  for nLine = 0, #mChoices do
   local sLine = "  "
   if nSelection == nLine then
    sLine = "> "
   end
   sLine = sLine .. mChoices[nLine]
   print(sLine)
  end
 
  local nWidth, nHeight = term.getSize()
  local y = nHeight
  local x = getRight("LNET Technologies")
  term.setCursorPos(x, y)
  term.write("LNET Technologies")
 
  local sEvent, nKey = os.pullEvent("key")
 
  if nKey == 200 then
   if mChoices[nSelection - 2] then
    nSelection = nSelection - 2
   end
  elseif nKey == 208 then
   if mChoices[nSelection + 2] then
    nSelection = nSelection + 2
   end
  elseif nKey == 28 then
   if mChoices[nSelection] then
    bLoop = false
    return nSelection
   end
  end
end
end
function menu()
repeat
  if nMenuNum == 0 then
   mChoices = {}
   mActions = {}
   mChoices[0] = "Login"
   mChoices[1] = " "
   if not fs.exists("/LNEX/data/retrieve/passuid") == true then

    mActions[0] = function()
	 bMenuLoop = false
	 term.clear()
	 shell.run("/LNEX/Client/LNEX")
    end
    mActions[2] = function() nMenuNum = 1 end
    mActions[4] = function()
	 term.clear()
	 os.shutdown()
    end
    mActions[6] = function()
	 term.clear()
	 os.reboot()
    end
    local nSelection = runMenu(mChoices, "LNEX Security Preface")
    mActions[nSelection]()
   else
    mChoices[2] = "Shutdown"
    mChoices[3] = " "
    mChoices[4] = "Reboot"
    mActions[0] = function() shell.run("/LNEX/Client/LNEX") end
    mActions[2] = function()
	 term.clear()
	 os.shutdown()
    end
    mActions[4] = function()
