JCL Intermediate/Advanced

 LENGTH OF COURSE:
 3 Days

DESCRIPTION: This course revisits the topics of Basic Job Control Language (JCL) and extends them to creating and manipulating JCL Procedures. Participants extend their knowledge of partitioned data sets, generation data groups, symbolic parameters and overriding catalogued procedures. Command JCL abends and their resolutions are presented. Students complete workshops which require them to code both instream and catalogued procedures as well as manipulating the procedure using overrides for both symbolics and data sets.

PREREQUISITES: Basic JCL and Basic TSO/ISPF

INSTRUCTION TECHNIQUES: A combination of Lecture, Exercises, and Labs (when/where available).

AUDIENCE

This course is designed for Application Programmers, System Programmers and anyone who has the need to write and manipulate instream and catalogue procedures during their development or maintenance efforts.

FROM OUR STUDENT EVALUATIONS...
"I think the instructor was responsible for the success of this course. I was kept very interested throughout the entire course. He didn't just read out of the text, he explained everything in such a way everyone could understand."
