DD Statements for In-Stream Datasets
When a job uses in-stream data, you can use a DD statement to assign a logical unit to the data
stream. You must still place the in-stream data after the EXEC statement, as in VSE.
* //
ddname
DD
specifier
[,OPTION=SYS
nnn
]
Parameter Required? Valid Default
specifier
Yes * or DATA None
SYSnnn No SYS000 to SYS254 None
* or DATA specifies that this statement defines an instream dataset.
SYSnnn specifies a programmer logical unit. Use this parameter if the ddname itself is not a
logical unit specification.
For example, if your COBOL program includes the following statement:
SELECT CARD-IN ASSIGN SYS005-UR-2540R-S-CARDIN.
then the DD statement would be:
* //CARDIN DD *,OPTION=SYS005
or
* //CARDIN DD DATA,OPTION=SYS005
If no external name is used (the ddname is itself a logical unit specification), do not use the
OPTION parameter.
For example, if your COBOL program includes the following statement:
SELECT CARD-IN ASSIGN SYS005-UR-2540R-S.
then the DD statement would be:
* //SYS005 DD *
or
* //SYS005 DD DATA
