If it's just persistent storage you're looking for, I suggest putting the state machine inside a single-run While with a shift register. There are at least three other ways I can think of to do what I assume you want, including local variables.

Some state machines do different things depending on the state of other state machines, so I use global variables in order to read other state machines' current state.
