IWASPOUT (Write Initialization Error Message)
The JES3 initialization modules use the IWASPOUT macro to write messages to the JES3OUT data set and, optionally, to the operator console, describing errors in an initialization statement.
For a summary of JES3 macros involved in message processing, see the topic Choosing the appropriate macro to issue a message.
Note: JES3 insures that it sends all critical error messages
(that is, for unrecoverable errors) issued by the IWASPOUT macro to
the operator's console by defaulting the WTO= parameter to Y when
the ERRLVL= parameter specifies C.
