[lua][question] Looping and entire program

I just want my program to loop to the top of the script when it's done. How would I do that?

Use a loop. To make an infinite loop, use:

while true do
  -- your code
end

To repeat for a given number of times:

for i = 1, <Times> do
  -- your code
end

There's more you can read about loops, the lua manual is a good place to look.

This is the a simple loop

while true do
    os.pullEvent() -- this is needed to stop program crash
    print("hello World")
end
