In this paper, we investigate the concept of unconditional transfer within various forms of regulated grammars like programmed grammars, matrix grammars, grammars with regular control, grammars controlled by bicoloured digraphs, and periodically time-variant grammars, especially regarding their descriptive capacity.

Moreover, we sketch the relations to restricted parallel mechanisms like k-, uniformly k-, partition-, and function-limited ETOL systems, as well as (unordered) scattered context grammars.

In this way, we solve a number of open problems from the literature.
