[Lua] Removing of return on full inventory

Hello all,
A pretty simple question that i have had a hunt for and found no answer for. I am new to programming so I am playing around with the excavate code. I wish to remove the return on full inventory part of the program. With the tunnel program, when the inventory is full, the turtle keeps going just dropping the items. How is it possible for the excavate program to do the same.
Thanks in advance for any help.
