Using shared variables instead of global variables

[Alan Anderson]

I don't see the connection between state machines and global variables. A state machine keeps its own state, and shouldn't need to share it with anything else, right?

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.
