    id NUMBER(5),
    first_name VARCHAR(80),
    last_name VARCHAR(80)
  );
  best_student student;
  another_student student;
  class_name VARCHAR2(80);
BEGIN
  class_name := 'FYI Center 2006';
  best_student.first_name := 'The';
  best_student.last_name := 'Best';
  DBMS_OUTPUT.PUT_LINE('Best student = ' || 
    best_student.first_name || ' '
