Message Control Statement

The Message control statement used in Real-time Auxiliary Disposition on Message Control Statement is also used in Batch Auxiliary Disposition. The Message control statement is optional. However, three exceptions should be noted when using this control statement in batch mode:

  1. The ddname does not have to match the ddname used in the JCL when the tape was read or written. The ddname can be any value.
  2. The Message control statement is not used for external label generation. In batch mode, external label generation is requested through a parameter on the DSN control statement.
  3. The user data option is not valid with Batch Auxiliary Disposition.
