Relationship to other parameters

Do not code the following DD parameters with the SYSOUT parameter.

DDNAME

AMP

DISP

PROTECT

CHKPT

DYNAM

QNAME

DATA

EXPDT

RETPD

DATACLAS

LABEL

SUBSYS

VOLUME

Ignored Parameters: Because JES allocates sysout data sets, the UNIT and SPACE parameters are ignored, if coded on a sysout DD statement.

Parameters on Procedure DD Statements that are Overridden: When an overriding DD statement contains a SYSOUT parameter, the system ignores a UNIT parameter on the overridden DD statement in the cataloged or in-stream procedure.

Naming a Sysout Data Set: Code the DSNAME parameter with the SYSOUT parameter if you wish to assign the last qualifier of the system-generated name to a sysout data set.

SYSOUT and DEST Subparameters: Do not code the SYSOUT writer-name subparameter when coding a DEST userid subparameter. These subparameters are mutually exclusive. You can code:

   //VALID1  DD  SYSOUT=D,DEST=(node,userid)
   //VALID2  DD  SYSOUT=(D,writer-name),DEST=(node)

With DCB Subparameters: JES2 ignores DCB=PRTSP=2 on a DD statement that also contains a SYSOUT parameter.

For JES, it is not necessary to select a specific BLKSIZE on the DCB parameter for performance reasons because the subsystem selects its own blocking.

INTRDR with OUTPUT Parameter: Do not code an OUTPUT parameter when the writer-name subparameter is INTRDR.
