It won't give any problem. I have executed one job with one DD name which is not used in program. I simply gave a statement like
//abcdef dd dummy.

My job was through. I dont think we will get any abend .

Thanks

I dont think the job will abend for a DD name since its an arbitrary name assigned to a dataset specified in DSN parameter. The utilities make use of certain DD names which if not given may cause problems. The S806 abend occurs if the dataset specified in DSN parameter is not found.

If you need a dataset in shr-old-mod disposition but it does not exist, you will have a Job Failed- Dataset Not Found

If you run a COBOL program but the DD that you try to open does not exist you will have a error in execution of I/O that will cause a user abend.

If you run a COBOL program that does not needs(read: does not open)an older dataset but the jcl is not update it will also work fine.

To my knowledge the only time a S806 abend occurs when running a Job is when a load module is invoked and it can't be found in any of the following associated with the Job:

Any of the system default loadlibs

Joblibs

Steplibs
