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