Thanks Wolfgang, but its not so easy. I knew this commands, but that is,
what I meant with this problems I had. In a large document often empty
pages (but with numbers) appear infront of a new part, or chapter,
because this new part has to be set on a odd page, for example. And so I
have always to deactivate all things, and activate them after this empty
page again, exactly with these commands above.
That is, why I had the pseudo-algorithm idea, that context should just
look after, which pages are empty, and to clear everything on them (or:
to not set anything on them, if there is no text). That would give
perfect result with only one single command, without switching all the way.
