Hi List,
What is the meaning of thro?
I have seen it here and there but never quite understood its purpose.

Actually, I will change it to your suggestion
for this situation, because with only two/three cases

(y = 2) ["Y is two"]
Thanks Joel, I think this is just what I need.
I don't think pif is a good name for it, though, it reminds
