I'd like to throw my vote out there if you don't mind. I very much appreciate seeing these kind of examples.

Walter has been a contrian on almost every topic if an example is given that doesn't match the VFP way. And for those of us not married to VFP, your work and sharing is very much appreciated.

Hi, Perry,

Thanks for your reply, I appreciate it. In fairness, Walter's second offering was fine, it seems to work just as well. These are (in part) academic exercises, so I'm also trying to think of implications of reusability.

Thanks,
Kevin
