Bletchley; Wow and Wow! This is great information and a fantastic lead to pursue. I sure appreciate the efforts here from everyone, as the group effort is a solution to my problem for one, of not enough time to dig as deep as the subject warrants at the speed one would like to do it. I'm sure lack of time is a matter for every one of us on this forum. Okay, I'm gonna jump on these with both feet and see where it goes. Wish us luck. Cheers; FM
