Well, I suppose so, if the why is 'why index 0' and not 'why data'.

I should probably point out that I was wrong when I said that ALL was a
macro, as well.  I wasn't paying enough attention and assumed that the ALL
was being passed to FETCH, where it is a macro, rather than to SEARCH, where
it isn't.  The point is still valid, though :)
