Hey, buddy,
this is great!!! i spent three hours trying to decipher your signature the morning before you posted explanations!!! I'm happy to see that i understood everything, but I said, it took me three hours!!!
being honest, i hadn't understood the last two question marks...i didn't remrmber that the m in the m/// operator could be omitted!!!
thanks for your lesson! it taught me many many things.
