Grid paper.png  Example
Tries to move the turtle forward x number of times. X is specified by the user and if the turtle can't move forward it will break the block infront of it.
Code
Arg = (...) -- gets the parameters from the user
if Arg ~= nil then
 Arg = tonumber (Arg) -- make it a number
 a = 1
 while a <= Arg do
  if not turtle.forward() then
   turtle.dig()
   turtle.forward()
  end
 a = a + 1
 end
else
 print ("Missing parameter.")
end
Output Either the turtle moving the specified amount of times or missing parameter.

end
Output The turtle moves forward.
