Help With My Code

distance = io.read() -- double "==" are only used when we are comparing a value, e.g., [if distance == 20 then]
distance = tonumber(distance)

-- Branch Mining Script
-- Variables
local distance = nil

-- Functions
-- Digging Functions

function digFwd()
  repeat
    turtle.dig()
    sleep(0.4)
  until turtle.forward() --Your turtle wouldn't have moved forward before
end

function digUp()
  repeat
    sleep(0.4)
  until not turtle.digUp() --this just makes your code a bit neater
end

-- Input Function
function input()
  print("How many meters is this mine going to go?")
  distance = io.read()
  distance = tonumber(distance)
end

-- Input Phase
term.clear()
term.setCursorPos(1,1)
print("This is a branch mining program.")
print("--------------------------------")
input() --you forgot parentheses here

-- Digging the mine

turtle.dig()
turtle.forward()
distance = distance - 1 --only need the one "=" here
repeat
  digUp()
  digFwd()
  distance = distance - 1 --again only need one "="
until distance == 0 --here we have two "="s because we are comparing two values
turtle.digUp()

EDIT: In continuing reading:

You are using 'while' loops in a weird way. A while loops is used to loop code but you are not wanting anything looped. Take a look at your code rewritten:

	turtle.dig()
	sleep(0.4)

  digUp()
  digFwd()

turtle.digUp()

I have not tested this btw

I now have an end of file error on line 52, Idk what that means.
