fixed error.  5th arg to user defined super instruction with intent w now initialized to zero

Bug was cut and paste error--instead of initializing the 5th argument, it was
checking the 4th arg again.

This initialization was a quick fix  to deal with super instruction bugs.
Super instructions should do this themselves, only if needed.
