Hi Andrzej,

Actually there was no Module in version 1. (e.g. see the documentation for

Yes indeed. The moment I read your reply I recalled having read about it
somewhere (Wagner's book perhaps) - also that one of the main reasons for
its appearance was that Block is a dynamic scoping construct and lots of
people were confused by the name and using it as a lexical scoping construct
instead, which of course is very error-prone.

Well, thanks. Somehow all of them came out as results of my experiments with
Mathematica, at the times when I did not have  Maeder's books or other
sources of information on this topic.  I actually think that I would not
have come to them had I known more about Mathematica at the time.

Regards,
Leonid
