Hi

Hi, two questions about states in statechart: 1. How (if possible) to implement this: a state upon an event generates an event and transits to another state?

With "generates an event", I guess you mean posts an event. Yes, you can do that in a custom reaction

2. Can a state have private nondestroyable memory?

No. As a workaround you can put the variables into an outer state or the state machine itself, but of course then they aren't private anymore. HTH, -- Andreas Huber When replying by private email, please remove the words spam and trap from the address shown in the header.
