This course is a combination of lecture, discussion and hands-on lab sessions.
First, an overview of JCL is given which describes the purpose of JCL, its relationship to the operating system, and the format / rules for coding.
Then, the JOB, EXEC and DD statements are covered extensively.
The purpose and use of each statement is described in detail; along with many parameters available to provide information to the operating system.
Procedures and several commonly used IBM utilities are covered in detail.
