Thanks, Lee. Mealy and Moore can always be alternatively used describe the same FSM. Lahman’s reason to adamantly insist on Moore is that Mealy treads on the “I’m done” perspective of events by implying events indicate “Do this.” So, good advice but opinions certainly could vary.

Right. There wasn’t an mention of what changing the mode property meant to the instance, let alone the instance SM. I was conflating mode and state. I looked at the GPS model but the display doesn’t even have an instance, just a class state machine whose actions change properties on instances of other classes and the UI.
