JCL

Requirements

For uncontrolled tape or disk datasets, use the proper label, for example,

TLBL, DLBL, or a DD statement with UNIT.

Note:Note:

This applies to GDI only. You cannot use GDIUR with uncontrolled

datasets.

For controlled datasets, no JCL changes are required for GDI input (GDI

only). For GDI output and GDIUR input and output, you must invoke

GDI by changing the label type to TLBL or DLBL, or device type to

UNIT=type. No volume or allocation information needs to be supplied

in the JCL. For GDIUR, use DD statements. You cannot use a DLBL

statement or TLBL statement.

When using GDIUR, it may be necessary to insert the OPTION=RESET

parameter on the DD statement after the step to terminate GDIUR

processing if subsequent steps reference the same system dataset DTF

name and you don't need to control it further using GDIUR. See Chapter

6, “

OPTION Parameter,” Reset, in this manual for more information.

Example The following example routes punch output to a disk dataset using

GDIUR.

* //IJSYSPH DD DSN='CARD.OUTPUT',DISP=(NEW,PASS),

* // UNIT=DISK

// EXEC PROGRAM

* //IJSYSPH DD OPTION=RESET
