This statement conditionally stops the execution of the current action (regardless of execution mode), and flushes the call stack until it finds the last started Repeat Forever statement. If found, the Repeat Forever's action's first statement will be the next to execute. If not found, this statement is equivalent to Stop. The statement can be executed always or only if the action test state is true or false.
The statement can also optionally set the action test state to true or false if the statement is executed.
