Interesting. I've never needed to do that. When writing console apps
(which haven't been many), I haven't made the screen scroll, so
^(esc)[J
or "^L" has been fine.
I don't think we can do it without access to the window itself, or a
method provided by RT to do just htat.

system/console/history
is the place, where you should look. This allows some more tricks, as
replaying your session etc. .
So
>> clear system/console/history
should do, what you are looking for.

Unfourtunately this is not I was looking for.
system/console/history holds the lines I wrote.
But I mean that the window scroll buffer.
For example I print some output, say 500 rows,
then clear the screen with prin "^L" (and clear system/console/history,
which is not the case) but when user scrolls window up using mouse-wheel
or scroll bar, then old rows will be shown.
There is Scroll Buffer Lines settings in Settings window on View
Console.
So I tought that it is stored somewhere in system object.
By the way when I change this Scroll Buffer Lines setting buffer gets
cleared

It works without form.
call/show system/options/boot quit

This is drastic; scraping instead of cleansing.)
Then you could also set the scroll buffer lines to 25.

not always. If you use a large buffer, it seems to depend of other
cirscumstamces.
