this code processes a rc from EXIT, CONTINUE and RETURN statement. All
these statements are defined independent to outer loops, so there are
no reason why this code has be different. And actually removed code
was almost same. There was different a process for FOR statement,
because there isn't possible direct "return" from cycle, because is
necessary to release a allocated memory.
There is no reason why the processing should be same, but actually is same.
