Introduction:


JCL stands for Job Control language. JCL mainly used to define, control the job to execute the program to get the desired output. JCL is combination of steps where each step has a specific task to complete. JCL links the program and input/output files in batch environment. JCL primarily acts as a bridge between the Operating System and program. JCL mainly used for the data processing in the mainframe environment with or without executing the cobol program.


Audiences:


Readers who are having or not having mainframe knowledge.


Objective:


The tutorial is intended for the readers with no previous programming or computer science experience as well as for those with some computing background. In the tutorial, all the topics are covered with in depth description and can understandable by anyone who had minimum/no computation background.


Prerequisites:


Need to learn COBOL language if learning the JCL for compiling and running COBOL programs. Learn COBOL tutorial at COBOL Tutorial.


There are no prerequisites to learn JCL language if learning the JCL only 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.
