The JCL (z/OS) - Using Special Data Sets in Batch Jobs course examines how special data sets, such as generation data groups, tape data sets, and temporary data sets are referenced using JCL. It also describes how data sets can be concatenated in JCL and some of the reserved DD statement names and their uses.
Operators, application programmers, or system programmers who require an in-depth knowledge of JCL.
