Usually I mean what I say. ;-)
Four steps is easy – one example is your solution, another one is...

Code:

#009
RMDR
x=0?
X<> L

Well, at least for x>0. ;-)

So four steps is trivial. For less it takes some real art of programming.
No, I do not have a three-step-solution either. Which does not mean it doesn't exist. ;-)
