Thank you all for your explanations. I can't say that I perfectly understand but I certainly do better than I did before. I really appreciate all the responses.

Thank you all for your explanations.

You're welcome. Thank you for your sincere questions.

BTW Yaelle, you hold a special significance for me in that my first post on Free Republic was to you. Who would have thought it would be a couple of thousand posts later that I'd make my second, and now my third.

Best FRegards,
