-------- will Defines libraries used for an entire job or one job step?
-
Joblib
-
Proclib
-
JCLlib
-
Steplib
A
Correct answer
Explanation
Joblib is the JCL statement that defines libraries (like JOBLIB or STEPLIB) used for an entire job or a single job step. JOBLIB applies to all steps in the job, while STEPLIB applies only to the specific step where it's coded. Proclib defines procedure libraries, JCLlib is not a standard JCL statement, and Steplib is a misspelling of the correct STEPLIB.
