  16. val interrupted: Boolean

    Interrupted flag indicates if the statement has been interrupted, and is used for skipping the execution of the conditional statements, by setting the hasNext to be false.

    Interrupted flag indicates if the statement has been interrupted, and is used for skipping the execution of the conditional statements, by setting the hasNext to be false. Interrupt is issued by the CONTINUE HANDLER when the conditional statement's conditional expression throws an exception, and is issued by the Leave Statement when the ForStatementExec executes the Leave Statement injected by the EXIT HANDLER.
