Ah yes, that is J but I would prefer that it not be that, perhaps _. = 0*_
There is no good answer, Roger picked what he thought best. For example I would prefer 0%0 be 1, makes my series first slot work better. I suspect a response of _. for most if not all of these, or some error stop, would, at the least alert the user/writer to some special problem.
