RESET Ends the Generic Device Independence for Unit
Record (GDIUR) control of a dataset. If you use
OPTION=RESET, it must be the only parameter
specified on the DD statement with other OPTION
subparameters used.
A dataset definition (DD) statement with
OPTION=RESET is required when the job does not
contain TLBL, DLBL, or DD statements in any step
following the DD statement 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 used
to invoke GDIUR control of the dataset.
In the following 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 disk
dataset SYSIPT.DATA.
* //IJSYSIN DD DSN=SYSIPT.DATA,DISP=OLD
// EXEC LIBR
/*
* //IJSYSIN DD OPTION=RESET
// EXEC LIBR
LD L=IJSYSRS
/*
REW Rewinds the tape at close. REW overrides any
