 *
 *   This function is similar to Confirm () except that the message
 *   status or result code and description is output when the code
 *   is non-zero; overtime, result codes have replaced status codes
 *   and so we look in different places for codes in some MMEs;
 *
 *   the status and result code fields appear at different offsets
 *   in different messages; consequently, check the MMTYPE to find
 *   field;
