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. Huseyin
