Note: The message descriptor codes are selected by the bit configuration, where bit 0 corresponds to descriptor code 1. These codes are assigned to error messages ending with E. The descriptor code is used by CA XCOM Data Transport when issuing WTO macro instructions. z/OS inserts an indicator (a blank space followed by a + sign) at the start of the message.
