retn
Returns values and control to the caller.
The Mill architecture supports multiple return values not only on operations but for all functions, as many as there are belt positions. Still most will only have one or none at all, because that is what languages were and are designed for.
Return not only returns from the most recent call operation and ends a frame, but also from the most recent inner operation and exits a loop. This depends on whether it was a call or an inner that has been executed most recently. The Spiller keeps track of that.
