I suppose it would count as an error had he specified what the code written was trying to accomplish. in some cases, returning nil may not be an error but just a flag which drives a program in a different direction.

touché Although in this case, it was indeed a nil value which was never intended to drive the program any further

I agree

Missing quotation marks around w and r in open
Missing quotation mark to close string THIS IS SPAM
Missing do closer after both for statements
Wrong type of integrator (ipairs not pairs)

NOTE: It's purpose is to set monitorSide to the side a monitor is attached OR "none" if none. Keep that in mind.

local sides = {"left, "right", "top", "bottom", "front" "back}
local monitorSide = "none"

function check(side)
 if peripheral.getType(side) ~= "monitor" then monitorSide = side end
end

for i, v in pairs(sides) then
 check(v)
end

Fixed:

local sides = {"left", "right", "top", "bottom", "front", "back"}

local monitorSide = "none"

function check(side)
if peripheral.getType(side) == "monitor" then monitorSide = side end
end

for i, v in ipairs(sides) then
check(v)
end

- Added closing quotes on "left" and "back"
- Added comma to separate "front" and "back"
- Changed ~= to ==
- Changed pairs to ipairs

My code:

local function() dostuff
  locol numbers = {}
  local words = {one = 1, ten = 10, one hundred = 100, one thousand = 1000)
  for [i = 1 to 1 000] do
	if [i = 10 OR (i < 500 AND i > 300) ] do
	  numbers[i] = Math:random(1, i)
-[[
	else
	  numbers[i] = -i
	end
]]
  end
  local number = 0
  while [number < 1000] do
	for k,v in ipairs(words) do
	  if [numbers[number] = v] do
		term.print k
	  end
	end
  end
  return number[10] + numbers[400]
end

Ah, sneaky dan, using peripheral.getNames() instead of getTypes(). I see what you did.

Incorrect! It should be rs.getSides(), as he is making an auto-monitor wrapping program.

Omg I corrected a mod. I r smrt.

[Cranium]

Herp derp....He did use getType().....
Meh, I was tired.

Mods dont have to be great at coding. they just have to be good at moderating. now if you corrected dan200 or cloudy and it wasn't just a simple typo. then thats different.

He iterated through peripheral.getNames() instead of rs.getSides()

This one is difficult:

local testString = "This is a sample string";
local testSubString = string.sub(testString,5);
local indexOfSample = string.find(testSubString,"sample");
print(indexOfSample)

Works fine? Prints out 7. Is it supposed to do something else? (I'm not so familiar with string.find)
Only other thing I could think of was this:

local testString = "This is a sample string";
local s,e = string.find(testString,"sample");
print(testString:sub(s, e))

Or this:

local testString = "This is a sample string";
local testSubString = string.sub(testString,5)
local s,e = string.find(testSubString,"sample");
print(testString:sub(s, e))

Run it in computercraft, it prints 11. It's a bug in CC. It's easy to fix it, but I don't want to reveal the answer.

Ah forgot about that one. Here then:

local testString = "This is a sample string";
local testSubString = string.sub(testString,5);
local indexOfSample = string.find(testSubString.."","sample");
print(indexOfSample)

(can't test it since I don't have access to Minecraft right now)

No error code? Wellwell, here goes

counterVar == 0
while true do
  countervar = counterVar+1
  os.PullEvent("Redstone")
  For i = 1,counterVar
    For j = 1, i
      term.write("*')
    end
    Term.write("\newline");
   end
 term.write("\newline")

end

- == instead of = in first line
- some fixes because Lua is case-sensitive
- there were no do's after the for statements
- you use " to open a string and ' to close it
- "print("\newline")" would print "
ewline"
- there was a missing end at the end
Edit: I missed that term.write() can't print \n

[MudkipTheEpic]

term.write doesnt accept \n's. Its write that parses those.
