Don't you think that you placed toooooooooooooooooo many assignments/questions into your post   ?     ? ?      ? ? ?


I think so.


Let me remind you that the RULES of this FORUM allow one and only one problem/question per post.


So, PLEASE consider and accept my best advise to you :


    SPLIT your post into the series of separate questions.


    It is the only way to get at least something instead of getting nothing.

------------

I could deliver a long lecture to you why it is bad to place many questions into one post.

But in the short form, in this case you will get such a HUGE output, which will be very difficult to read.

Or will get nothing, at all . . . which is even more likely . . .
