|WHY does it work?

The result of the _calculation_ was placed into the register used to
return the value to the caller (ax?). The addition of the _assignment_
did not have to disturb this register. Try using "dummy=222*num;" instead.
This will force another calculation, and should overwrite the `correct'
result.
