Processing control by external writer

To request that a sysout data set be processed by an IBM-supplied or user-written external writer, rather than the installation's JES, code one of the following:

   //ddname  DD  SYSOUT=(class,writer-name)

   //name    OUTPUT WRITER=writer-name
   //ddname  DD     SYSOUT=class,OUTPUT=*.name


   //name    OUTPUT DEFAULT=YES,WRITER=writer-name
   //ddname  DD     SYSOUT=class

For an external writer, the operator determines which sysout data sets are selected. This can cause certain data sets to be printed on the same listing even though all of the forms, FCB, UCS, and DEST parameters are not the same. The operator must start the external writer for a sysout data set to be printed or punched.

For more information on external writers, see z/OS JES2 Initialization and Tuning Guide or z/OS JES3 Initialization and Tuning Guide.

Examples

//DS1  DD     SYSOUT=(H,MYWRIT)

//OTA  OUTPUT WRITER=MYWRIT
//DS1  DD     SYSOUT=H,OUTPUT=*.OTA


//OTB   OUTPUT DEFAULT=YES,WRITER=MYWRIT
//DS1   DD     SYSOUT=H
