Writing a tunneling program - that goes through lava...

So quick explanation first: When I mine, I dig in a straight line - then every 3rd block I create a perpindicular path. I wrote a program that digs a tunnel; digs out the walls - and replaces them cobblestone. Basically, I end up with a 1 x 3 tunnel, where everything around it (top, bottom and sides) is dug out and replaced with cobblestone.

My problem is bedrock. Currently, to account for gravel - I dig and check again if there's a block; and keep doing that until I can place cobble. Bedrock is a problem - any way around this? Currently, I just try 5 times and then give up; but is there a better way of getting around cobble?

Here's my current code:

local function PlaceBlock()
checker = 0
  while turtle.place() == false do
   if turtle.detect() == false then
	turtle.attack()
	turtle.place()
   else
	turtle.dig()
	turtle.place()
	checker = checker +1
	sleep(0.25)
	if checker > 5 then
	 return
   end
  end
end
end 

Please tell me there's a better way of doing this? :)/>

Ugh; I was being dumb - I fixed my code by saying if turtle.dig = false; it's bedrock… otherwise, try to place the block; if that fails - it'd keep trying because it's most likely gravel…

function down()
  turtle.select(16)
  while turtle.detectDown() do
    turtle.digDown()
    if turtle.detectDown() then
	  return nil
    end
  end
  if not checkFuel() then
    return false
  end
  while not turtle.down() do
    turtle.attackDown()
  end
  depth=depth+1
  return true
end

Look at this sample of code. It return true if have moved down and digging. Return false - if have no fuel. And return nil - when stucked with some undiggable.

It's quite simple : If you can't dig and there is a block, it is bedrock !

the code wasn't going down in OP, it was going forward.

It's a SAMPLE.
