That was just what I needed.  Your description was clear and easy to follow.

I couldn't agree more.  This was a learning exercise for me.  In a real
program (one that I or someone else would have to maintain a year or so from
now) I would have stopped with the first version, with all the loops and
intermediate variables left in.  

Thanks for your help.  I really enjoy this list.
