Its a maze game. It should be obvious what to do.
Arrow keys to move, and spacebar to put a letter back down if you messed up

Time-wise, using a placeholder variable is best, as shown by this code

Of course, if you're not calling it hundreds of thousands times, the difference will be negligible (besides which, rednet.receive yields until it gets a message or timeout, so that will take much longer than getting the second return value)

I believe that's because of the margin around the whole screen. If the colors didn't fill it in, there would always be a black line surrounding the screen. But without the margin, characters near the edge of the screen would probably look too close to it.

if you want to run a program from inside of a program, you need to use shell.run, like

shell.run('program', 'argument1', 'argument2')

So replace every line like

run monitor top ToDo

with

shell.run('monitor', 'top', 'ToDo')

You also need to have an end statement for every if statement, to mark where the code in the if statement (that you only want to run if the condition is true) ends, like

if condition then
  -- Do stuff
end

Just change note in

note = read()

to some other variable name (like input), and use than same name when you check if its "exit". THat way it won't overwrite the opened file which is stored to note

The version of ComputerCraft used in tekkit (1.33) doesn't include the keys API, which that program uses (though it can be copied to the computer if the server has http enabled, or you can use the key codes directly) . There's also no paintutils API, because there aren't advanced computers/colors, so any attempt to use that will also cause an error.

followed the turtles

When you open the file in recall, nothing has actually been written to the file because you haven't called file.close. In the main part, Instead of opening the file once per loop, I'd probably open it each time a command needs to be added (in append mode), write the command, and close it
Immediately after. (also close it in recall after reading from it)

You may want to reset the file contents at the end of recall, which can be done by opening the file in write mode then closing it again

From looking at this, it appears that the turtle moves forward in the

if turtle.forward() == false then

and again in the else block since it moved =, and therefore wasn't false. So you should try removeing the else in Gravel

Since the directions are also in the API, you need to do

quarry.move(quarry.Left)

Are you sure you're passing a direction (number) to the move function when you call it?

Local functions in APIs can only be called from within the API. If you want an API function to be accessible from other programs, it needs to not be declared as local..

After defining the functions using the function keyword, you call them separately from the code. Example:

function exampleFunction()
	--do stuff
end

exampleFunction() -- calls the function

Call it the same way you would call print, sleep, or read, just

selection() -- If it took arguments, they would go between the parentheses

You'll also have to call newMenu the same way when you want it to run.

You need and end for the if/else block, after

guess = guess + 1

.
The end on the last line should be removed, because repeat until loops don't use an end statement.

If you want to clear a file, you can open it in mode 'w'. That will fix both of the problems at once.

local file = fs.open("users/"..usrName,"r")
local line = file.readLine()
while line do
	table.insert(fileData, line)
	line = file.readLine()
end
until line == nil -- readLine()
file.close()
local oldpassFromFile = fileData[1]
if oldpass == oldpassFromFile then
file = fs.open('users/'..usrName,'w') -- Changed from file.clear()
file.writeLine(newpass)
file.close()

It reads a password from the file '/password' (Default is 'password' is the file doesn't exist) and asks the user for it until it's entered.

Features:
- 20 second fake startup sequence (during which it can be terminated)
- Hard to read code
- Highly innefficient
