Hi Gary,

I'm presenting the MI behavior as confirmation of what I would expect to
happen.  Whenever the system cannot perform the instruction it should signal
an exception.
Adding to a null pointer is something that the system cant do and it has to
tell, that is signal, the executing program of that condition.

What kind of an exception, RPGesque or otherwise, doesnt except? :)
