Turtle Detecting Program Help

So I am writing a program for a turtle tree farm and I want my turtle to dig up until turtle.detectUp() == false
this is what i am thinking:

function uptill()
	 while turtle.detectUp() == true do
		  turtle.digUp()
		  turtle.up()
	 until turtle.detectUp() == false
--[ at which point i want it to come back down until turtle.detectDown == true ]--

local height = 0
while turtle.detectUp() do
  turtle.digUp()
  turtle.up()
  height = height + 1
end
repeat
  turtle.down()
  height = height - 1
until height == 0

That should work for you!

why not just this since a tree can only grow on a block

while turtle.detectUp() do
  turtle.digUp()
  turtle.up()
end
while turtle.down()
end

That may be true, but I always like to count how far I have traveled. It helps me figure out where I can add in additional code, such as detecting more leaves, or other things. Just a personal preference.

Thanks :D/> That counting how far up then going down that many was a good idea! Never would have thought of it ;)/>
