The parameter NEW_STATUS shows the new status (technical text andlanguage-dependent description) after the call.
The parameters RETURN_CODE and MESSAGE_LINES show whether the call wassuccessful. RETURN_CODE has a numeric value, and MESSAGE_LINES gives atextual explanation for finer differentiation.
