Loop a whole program?

I have a code and I want it to loop completely again, so I don't have to write the program 5 times.
Here is the code I have currently

for i = 1, 5 do
  turtle.dig()
  turtle.forward()
  turtle.digUp()
end
for i = 1, 1 do
  turtle.turnLeft()
  turtle.dig()
  turtle.digUp()
  turtle.forward()
  turtle.turnLeft()
end
for i = 1, 5 do
  turtle.dig()
  turtle.forward()
end
for i =  1, 1 do
  turtle.turnRight()
  turtle.dig()
  turtle.forward()
  turtle.digUp()
  turtle.turnRight()
end

What I want to do is repeat this code all over again. I guessed i would just put an i = x, y do statement, but that didn't work. I dont know what else i could do, so if anyone could help, that would be nice :)/>
This is supposed to clear an area, just in case you want to know

okay so I'm not completely sure you understand how loops work. Especially due to the following

for i = 1, 1 do
  --# code
end

that code will run once, the format of a for loop is as follows

for variable_name = initial_value, value_limit [, optional_increment] do
  --# code
end

meaning that doing for i = 1, 1 do tells the loop to run until i equals 1, which is once.

now to run all that code 5 times, you just simply put it inside of a for loop as well, like so

for y = 1, 5 do
  for i = 1, 5 do
    turtle.dig()
    turtle.forward()
    turtle.digUp()
  end


  --# removed the needless loop
  turtle.turnLeft()
  turtle.dig()
  turtle.digUp()
  turtle.forward()
  turtle.turnLeft()


  for i = 1, 5 do
    turtle.dig()
    turtle.forward()
  end

  --# removed the needless loop

  turtle.turnRight()
  turtle.dig()
  turtle.forward()
  turtle.digUp()
  turtle.turnRight()
end
