Yes. The possibility is supported to cancel implicit rules (which refer to targets that contain the placeholder “%”) on demand during a specific construction sequence. > Only if an explicit rule does not exist will an implicit rule search > be performed.

They correspond to a special category of programming languages. I find that there are also functions supported which are immediately executed. Regards, Markus
