JCL (EN/NL/FR)

In this two-day ABIS training, you learn all syntax details of JCL, the Job Control Language of IBM.

JCL, the Job Control Language of IBM, is mainly used in a mainframe environment or on a MicroFocus Enterprise Server. JCL instructions allow us to launch applications in a non-interactive (i.e., "batch") way.

During this course you learn

• to write JCL statements to obtain a correct execution of programs and to pass them the correct (input and output) data sets;
• to interpret the returned (error) messages via SDSF (Spool Display and Search Facility);
• to write, use and test JCL procedures.

Intended for

Programmers, operators, system programmers, schedulers.

Backgroud

Basic knowledge of ISPF is necessary (see course ISPF/PDF basics).

You can test yourself to see if you have enough background by filling out the online selftest.
