‘SORTWORKdd’ is not Mandatory in DFSORT JCL

In this post, I have shown how DFSORT speeds up its sort processing even when you are not supplied “sortworkdd”.


Why SORTWORKdd is not mandatory:

//SORTWKdd DD :

Defines a work data set for a sort. Typically not needed, because DFSORT can allocate work data sets for a sort dynamically.

Why STEPLIB not needed for SORT JCL:

/STEPLIB DD :

The DFSORT program would typically be in a library known to the system, so the //STEPLIB DD statement would not be needed.

However, if DFSORT is not in a library known to the system, the //STEPLIB DD statement defines the library containing the DFSORT program.
