Objective and Audiences -

In this tutorial, all the topics are covered with in-depth information. So, this tutorial is advised for all developers.

Prerequisites -

There are no prerequisites to learn JCL language if learning the JCL for file manipulations. Having the computation background will be an advantage in understanding the concepts a bit easy. Without having computation background, it is a bit time taking to understand the concepts and need to go through the topic more than once to understand clearly.
