That's great.  Thanks very much.  I thought about starting the Zorch 
counter at zero, but I just figured that this would make the labels of
the "Zorch"es 1 too small.  I didn't see (I feel kind of "duh" now) that
putting the \refstepcounter{} call *before* the \section*{} call would 
fix this.

I *knew* there'd be a simple fix, that I was just too stupid to see.

Thanks again to Susan and Herbert.

cheers,
