No, I tested the code you linked to, Yuri, and it works fine, for what it was intended to do.

I see we have at least 3 codes for Marvin's needs now! It's not all that difficult to write, once the problem is understood. That's the main problem.

So *you* did the code, *I* did the code, but *Jay* already posted code that looks very good. But just in case, you and I can keep our code handy :-)
