  SELECT commission_pct
  INTO n_pct
  FROM employees
  WHERE employee_id = n_emp_id;
  -- evalutate commission percentage
  CASE n_pct
  WHEN 0 THEN

The client makes the call (e.g. passing the PL/SQL anon block to the server to be parsed and executed).
This is successful. The server returns a zero return code to that client call. This means successful completion of that database call.
The client can now choose to display any message it wants to inform the user of that - from "+hey dude, it worked!+" to "+command completed successfully+" or whatever.
The database does not return a message string in response to that call - only a return code. What the client can do is make another call and request the associated message from the client driver for that return code. In this case, an English language message file (as queried by the driver) will return the message string, "+normal, successful completion+".
