But the new %lookup builtin does a binary search for ordered arrays. %lookup can behave this new (new for RPG ...) way because there's no compatability issue. (LOOKUP can't change to a binary search because of possibly desirable behaviour with arrays that are not actually sorted. We won't change the behaviour, whether or not it's documented.)
