Thanks for all the responses. For the record I asked the question badly.
I typed nil when I meant 0 and I understood the syntax and most of the
meaning. My confusion stemmed from the test for what I thought was a

I guess the lesson here is that I should probably not attempt to pose
queries while playing with my grandchildren.
