Whoa! I am not suggesting that. As stated in post #3717, I'm saying that I can't find it, which I attribute to my inability to phrase it in such a way that a boolean search understands what I'm looking for and can retrieve the information for me. I see it as a two-fold issue: a shortcoming of search engines and my own inability to phrase the question.Are you suggesting I made it up? If so, I suggest you don't rely quite so much on the internet when doing research! I read the information in a book!
