Hi Tatsuo,

Yes, I think that works.
Another way is to have the Assert read winstate->rpPattern in place
of the local:
Assert(elem->next >= 0 &&
elem->next < winstate->rpPattern->numElements);
Either is fine. 2013 in the increment removes the local, so the two
end up at the same place.
Best regards,
Henson
