Hi,

Could anyone explain the difference between IKJEFT1A & IKJEFT01? Are they same or different?

Well, you could look them up in the manual or search the forum/web for the information but basically they are the same but different.

This might help -- IKJEFT1A intercepts application abend codes (as in, will not pass them to JES for subsequent return-code checking in JCL), but will pass system abends to JES. Any data-sets that are defined as DISP=(NEW,CATLG,DELETE) will be cataloged in the case of an application abend, since the job step will terminate normally. In the case of a system abend, the data-sets will be deleted.

IKJEFT01, on the other hand, intercepts any system/application abend codes. It will also not pass them to JES for subsequent return-code checking in JCL. Also, any data-sets that are defined as DISP=(NEW,CATLG,DELETE) will be cataloged, since the job step will terminate normally even if there is an abend.

There is another brother of them (as a song says, brother from another mother, though, here I think mother is same too*) -- IKJEFT1B -- it does not intercept either system or application abend codes. And all abend codes are passed to JES for subsequent return-code checking in JCL. Any data-sets that are defined as DISP=(NEW,CATLG,DELETE) will be deleted in the case of a system or application abend.

And this IBM link has a detailed explanation about them.

Thanks Anuj.

You're welcome - hope we had been helpful.
