The function returns a vector of even length that contains two elements for every sequence object that is now stored in the database: the name and the current state. The order of 'name-state' pairs in the resulting vector may vary from call to call. To search such a vector by a setting name, the vector can be passed as a second argument to the function get_keyword().
Changes in the returned vector will not alter sequence objects of the database. To change actual sequence objects, use sequence_set().
