Thank you, that is a helpful answer. Your first response seemed almost patronizing, though I am sure you didn't intend that. But it alienated me so much that I didn't realize the 2nd response, from David Potter (who looks a lot like you btw, lol) did have a link to the solution. I think, haven't tried it yet, but it appears so

I just saw all this stuff about how to search a forum, and noting that I had posted my version, but then telling me I should post my version. It was a little put offish. I am probably too sensitive, just wasn't much of a welcome to anew forum for me.
Anyway, thanks to both of you. I think that article willl solve it, be trying in the morning, but it does say ARCH at the top. I hadn't notice that line Eric, in my first article that does not include my version. Now I know to look for that. Thanks for that info.
