Dear Walter,

Thanks very much for your input and also your code. I received a similar message from Marc Grajower.

I am presently working on code sent to me from Cetin and Hilmar. Would like to come to terms with this problem at the earliest. On the positive side, I'm glad to see that this situation is not uncommon in the programming arena, and it would be nice for all of us to come to terms with the best possible code for it.

Will be posted on UT soon.

Unfortunately, my work keeps me on the move, so if the gaps are slightly long, please excuse me.

With best regards,

Steve.
