DD Statements for Tape and Disk Datasets
OPTION Parameter
ALLMSGS
Overrides configuration options ALLMALL=NO (default) and ALLMSG=NO for this dataset
in the current job step only. It enables all allocation messages for the disk dataset. This
subparameter performs the same function as the BIM-EPIC DLBL option 'M'. The
ALLMSGS subparameter is valid for disk datasets only and is ignored if specified for a tape
dataset.
CAT=ddname
Specifies the DD name used in a previous DD or DLBL statement to define this dataset's
VSAM catalog. Use this parameter only when you are defining a VSAM dataset. It will
override any JOBCAT or STEPCAT statement for the dataset.
CISIZE=nnnn
Specifies the CISIZE to be used for an FBA disk dataset according to IBM rules. NOTE: If
the dataset is a Start Track 1 dataset and CISIZE= is specified, specification of the maximum
number of secondary extents in the VOLUME parameter is ignored.
NOREW
OPTION=NOREW can be used to not rewind the tape at close. It overrides any rewind
option defaulted to by the DISP or VOL parameters.
RESET
Specifies that the control of a dataset by the Generic Device Independence for Unit Record
(GDIUR) feature is to be ended. If OPTION=RESET is used, it must be the only parameter
specified on the DD statement, and no other OPTION subparameter can be used.
A DD statement with OPTION=RESET is only required when the job contains no TLBL,
DLBL, or DD statements in any step following the DD statement that was used to invoke
GDIUR control of the dataset. The ddname on the DD statement that specifies
OPTION=RESET must be the same as the ddname on the DD statement that was used to
invoke GDIUR control of the dataset.
RESET Example
In this example, SYSIPT control statements are read by the first LIBR execution from the tape
or disk dataset "SYSIPT.DATA". The second DD statement for IJSYSIN with the
OPTION=RESET insures that the SYSIPT control statements for the second LIBR execution
will be read from the instream data, not from the "SYSIPT.DATA" dataset.
* //IJSYSIN DD
// EXEC LIBR
/*
* //IJSYSIN DD

REW
DSN=SYSIPT.DATA,DISP=OLD
OPTION=RESET
OPTION=REW can be used to rewind the tape at close. It overrides any rewind option
defaulted to by the DISP or VOL parameters.
