By definition: "The scope extends textually from the point of the declaration to the end of the block (procedure or module)". By saying that, "within its declaration" can be considered the same "within its scope".

It's pretty unambiguous to me that the procedure identifier refers to a local object that identify the procedure itself.

So in your example in both cases Q and R activate recursively in Oberon-07.
