JCL training course (code: JCL)


This JCL  course teaches the student to code and test efficient JCL. It is designed for programmers, developers, operators and production control staff who need to submit and run jobs on z/OS.Client feedback shows that delegates on our courses will best engage when they can relate course topics to their own day-to-day practices and requirements. Where possible, we  run this course as a consultative, workshop-style event, in which discussion of relevant topics takes place in relation to the delegates' own applications and scenarios.


Users who need to initiate batch jobs for processing in an z/OS environment. Programmers who will be using the IBM mainframe for program testing.
