Folks, I see a new application programming guide released in March 2004
called : z/OS V1R5.0 DFSORT Application Programming Guide.

What is this new release for?? Are there any changes to the earlier one?
I read the summary of changes but couldnt make out what was new ?

Have they just brought out a new doc for z/os ?? In what way would this differ from dfsortd for earlier versions?

sorry if this is a very daft question...but am curious.

z/OS DFSORT V1R5 became available in March, 2004.

The major new function available with z/OS DFSORT V1R5 is memory object sorting. New parameters NULLOUT, NULLOFL and MOSIZE are also available and some of the shipped installation defaults have been changed. For details, see:

http://www.storage.ibm.com/software/sort/mvs/summary_changes/srtmsocc.html#b15

Note that you must have z/OS V1R5 to use z/OS DFSORT V1R5.

The z/OS DFSORT V1R5 publications have been updated to reflect these new functions as well as the enhancements that were available earlier with DFSORT R14 PTF UQ90053 (Feb, 2003). Note that although both z/OS DFSORT V1R5 and DFSORT R14 include the PTF UQ90053 enhancements, only the z/OS DFSORT V1R5 books have been updated with those enhancements (we only update the latest version of the books).

All of the DFSORT books for z/OS DFSORT V1R5 and DFSORT R14 are available at:

http://www.storage.ibm.com/software/sort/mvs/srtmpub.html

You can use the z/OS DFSORT V1R5 books for DFSORT R14 keeping in mind that only z/OS DFSORT V1R5 has memory object sorting, MOSIZE, NULLOUT and NULLOFL.

Thanks Frank. NULLOUT and NULLOFL could be very useful. I plan to check if this version is installed and if not get our MVS team to install it. In case the options listed in the SYSOUT of any DFSORT job do not include NULLOUT and NULLOFL can I conclude that the version is not installed? Or would you advise doing some other check? Just want to double check lest i should face the wrath of our MVS team.

If you have z/OS V1R5 and you're using DFSORT, then you should have z/OS DFSORT V1R5. If you have z/OS V1R4 or OS/390, then you can't have z/OS DFSORT V1R5, but you can have DFSORT R14. Starting with z/OS V1R5, DFSORT matches the z/OS release. So z/OS DFSORT V1R5 and z/OS V1R5 go together.

If you don't know which z/OS release you're using, but you have the DFSORT messages, just look at message ICE000I to see which release you have.

Alternatively, you can run this job:

Thanks again Frank. We are still stuck in z/os ver1 rel2. That rules me out from taking advantage of the new features.NULLOUT was something I was hoping to use. Sad

Thanks anyways for the information.
