local distance = ... -- gets the first argument from the user
if distance ~= nil then
 distance = tonumber (distance) -- make it a number
 for i = 1, distance do
   turtle.forward()
 end
else
 print ("Did not specify distance.")
end
Output Either the turtle moving the specified amount of times or missing parameter.
