wiser to review Your ideas...IEFBR14 does not open the DD, so it's good for deleting, but not for allocating.
As mentioned, you are not correct here. IEFBR14 is not the utility of choice when allocating a new data set which will be opened for INPUT in a later step of the job; in this case it is better to use another utility such as IEBGENER that opens the data set for output in the allocation step. However, when allocating a data set which will be used for OUTPUT in a later step, IEFBR14 works just fine.IEFBR14 does not open the DD, so it's good for deleting, but not for allocating.
Thanks Robert. May be because of your experience, you can see it being used but I think it's not that usual...Robert Sample wrote:I've never heard IEFBR14 called the dummy utility, but I can see the term being used. IEFBR14 consists of a BR 14 assembler instruction, so all it really does is return to the calling program (usually the operating system).
I saw that link but I could not find if dummy is used somewhere to refer to IEFBR14, officially. "Do (almost) nothing" has been used for it but not dummy.Chandan Yadav wrote:IEFBR14 called as dummy utility because it almost do nothing. Please refer the link

Thanks William. Thanks again as I thought I behaved badly. What is "interview-writer"?I've never hard of IEFBR14 being called "the dummy utility". I'd have done exactly the same as Ankit. Although perhaps I'd have said a little more at the end. Everybody and their dog has used IEFBR14, and any site that thinks they've got a cool cutesy name for it, and that someone who is prepared to "guess" when given the cool, cutesy, name is somehow better qualified for the job is a pretty stupid site (or interviewer, or interview-writer - I suspect the latter here).
Thanks Anuj. That would make it meaningful, without context how would I understand it!I'll also not call it as "dummy utility". And if I do, I'll make a context about it, set-up it calling "dummy" among the attendees and then later I might use it in such context, without that it'll just create confusion nothing else.
I have cited an example a couple of times but it make sense to quote it again here - in an interview, I was asked trivial question, "what is the difference between OLD and KEEP in DISP parameter?"
I started by saying, if the site is SMS managed... and 15 minutes later we (read it as interviewer) agreed that SMS on zOS and "SMS" I got for the interview-location this morning are two dramatically different animals!
So did you mean there are other universal utilities from IBM which can be called "dummy utilities" apart from IEFBR14? And every utility which does not open the DD, souldbe called "dummy utility"?mmcrew wrote:When you talk about "dummy utilities", remember the following:

Use IEBGENER with SYSUT1 dummied and SYSUT2 with the correct DCB.
