Re: add to *Null pointer does not throw an exception.

Steve,

What makes you think there is a one-to-one mapping of Eval  Ptr = Ptr +
32 to MI's AddSpP instruction?

I would be surprised to learn that there is a one-to-one mapping even if
it were technically possible.

And for the fact that you think it should signal an exception...
Consider that the compiler could be generating exception handling code
to prevent that particular error. Perhaps just to throw its own
exception - a more RPGesque exception.

Food for thought.
