> Roby, are you aware that expr[] gives access to the head?
yes, this is clear to me.
But if you look carful at my post then you will see that I do not
access the element with the array index 0 (the Head).

again look carful at my post I don't want and I do not assign to
element [[1,1]], the assignment just happens by failure!

... perhaps right perhaps wrong, depends on the exact definition of
Span[ ] wich in turn should depend on what is recognized as suitable.
look at my reply to shizu there I have explained a reasonable
As the Mathematica behavior now is, I of course must prevent empty
I would prefer a defined behavoiur similar as e.g. for Range[1,0]
which returns an empty List.
One of the principles of Mathematica is elegant functional programming which
e.g. avoids thigs like loops etc., one of the helpful features in this
connection is Span[ ].
As explained I am looking for a construct that assigns a variable
number of elements that means even 0, 1 or any other random number
provided as a variable.
This works perfekt for Matrices < 15x15, pleeeeease, pleeeease fix it
for bigger ones.
By the way I have reported this to the Wolfram support.
The first answer was that the behaviour is "unexpected" and that the
issue is forwarded to the developers.
As I had the pleasure to meet you at the Mathematica 2011 Conference in Vienna
I would not be too much surpised if the isssu would be forwarded to
