-- Requires a digging (diamond pickaxe-equipped) turtle
--

--
-- Drop-off everything in specified slot
-- Preconditions : turtle is beneath the drop-off chest
--
-- Returns false if it could not drop off
--
function dropOff(slot)

  if turtle.getItemCount(slot) > 0 then
    turtle.select(slot)

    if not turtle.dropUp() then
      print( "Could not place into container above" )
      return false
    end
  end

  return true
end


-- Use 1st slot only
turtle.select(1)
gGuessBlocks = 0

--
-- Break blocks down for forever
-- Place blocks in chest above when have full stack of 64
--
while 1 do
  if  turtle.digDown() then
    gGuessBlocks = gGuessBlocks + 1
    if gGuessBlocks == 64 then
      dropOff(1)
      gGuessBlocks = 0
    end
  end
  sleep(1.5) -- sleep long enough for the cobblestone to form
end
