Target Audience

The course is aimed at developers not familiar with the z/OS development environment. This course covers the understanding and writing of JES/2 JCL. The course teaches the writing of JCL statements using the options and parameters available, and the creation of in-stream and cataloged procedures including the use of symbolic parameter substitution. All of the latest release features such as SMS, JCLLIB, SET statement and If/Then/Else/End-if Testing are included.

Pre-requisites

Whilst covering the basics of JCL and how it is used, this course also aims to give an insight into manipulating data and datasets, writing and testing JCL.

Course Objectives

Whilst covering the basics of an Introduction to IT, this course also aims to give an insight into the software used on both mainframes and PCs and how each piece of software interacts with each other. On completion of this course the student will be able to:

•     Understand and code a valid JCL JOB statement
•     Understand, code and execute simple JCL jobs
•     Understand, code and execute JCL using Generation Data Groups
•     Understand, code and execute JCL in-stream and catalogued procedures using symbolic variables
•     Understand, code and execute JCL dynamically overriding JCL parameters
•     Understand, code and execute JCL using JCLLIB, INCLUDE and SET Statements

Course Environment

Development will be performed using:

•     IBM Mainframe

Course Format

Practical sessions make up a large part of the course, allowing delegates to demonstrate and reinforce the lectures given. During these sessions the delegate will gain experience of writing and testing JCL statements using the options and parameters available, and the creation of in-stream and cataloged procedures including the use of symbolic parameter substitution. All of the latest release features such as SMS and If/Then/Else testing are also included. Examples are used extensively, ranging from simple code snippets to full applications with complete ‘real world’ functionality. These are supplied at the start of the course and it is encouraged that the delegates execute and ‘experiment’ with these under the instructor’s guidance as they are introduced. These examples are available to take away, along with the delegate’s own work. The comprehensive Student Guide supplied is fully indexed serving as a useful reference tool long after the course has finished. Delegates will also be able to access a free help-line with technical questions relating to topics covered on the course.
