I used this thing because I wanted the result of the script to be displayed as
block element.

If that's what you want, output something that's display:block.

OK, but should not display the "code" of the script.
Should display just the results of the scripts.

This what I see, the code is written on the page

Attachment: More Complex script

In this example you see that (maybe in the other it was clear enough) the
source of the script is rendered on the page

As I understand it, the text of a script only doesn't display because the script
has display:none. When you change it to display:block, the text shows up.

You could try doing document.write("<div>This text is written by a
script</div>"), or something equivalent.

The screenshot of the new page

So, in response to comment #7, you are telling me that the the fact that a the
code of the script is displayed is just because it has as default display:none?

Anyway I'll suggest that a script tag cannot have the source displayed on the page

That's my (albiet limited) understanding of it.

You should also note that when you document.write something, the result is _not_
a child of the script, so setting disply:block on the script doesn't affect the
thing being written anyway.

Verified invalid.  There's no reason we should prevent the script being
displayed if the page author wishes to display it.
