Hi,
What is the difference between DSNs allocated using IEFBR14 & NWOMC ?
By difference I mean, when some COBOL program will try to READ an DSN created using IEFBR14, it may abend if that DSN is never written to but this is not the case with NWOMC located DSNs, why so?
P.S.: I think, I don't know whether I put a right question or not and perhaps, may be that's why I don't know the right answer. I've seen below type of steps in many JOBs at my site, I know the purpose but not the significance when I ask myself "what if IEFBR14 was used?"

Who wrote/maintains NWOMC? It is not an IBM utility.
I was under the impression that this is an IBM utility & is in use across the shops. Actually, I checked in Source Base Library of my shop, this program was not there, so I thought it's a utility from the IBM side which invokes from the system libraries at run time.
Thanks for the clarification Dick, now I've different approach to look for the same query. By the way, how do we know that particular utility, such as imagined by me, is not from IBM utility list, any link ?

Hi Anuj,
Many of the IBM utilities are named IExxxxxx (IEBGENER, IEFBR14, IEHLIST, ETC). There are also ICExxxx, SORT, IDCAMS, etc.
I know of no list that names every IBM utility.
NWOMC might be an alias of some other module. . . Find the executable, browse it, and look for an eye-catcher that may give a clue as to who wrote it. Might it be part of FileAid? Is NWOMC in the steplib you point to or is it found in the link list?
