Mario Mario, here you go again, we sure missed you for a year or so, but here you are back with your easily identified style, even woithout signature I would have recognized you.
Only 4 questions, definitely below your average per post, but crossposted on 5 newsgroups?
You have Google, you have books surely, maybe you should use them and save your questions on the NG for more specific items.
Sigh
