Try and restate this question. What you are asking is what
is the value of an uninitialized variable. Well, it is
uninitialized so it has no value. However, I think you
are asking what variable is uninitialized. What you might want
to do is put some simple print statements above the line with
the variables in them, so you can tell which ones are empty.
I admit it, I am Paco.
