This 5 day class will introduce students to the skills necessary to code batch jobs using
OS/390 MVS and z/OS Job Control Language (JCL). The students will learn to code:
- JOB statements.
- EXEC statements.
- DD statements for disk data sets, tape data
sets, and printed reports.
The structure of OS/390 and z/OS job output and system messages are reviewed, and
common JCL errors examined.
Students will learn the skills necessary to define and use Generation Data Groups
(GDGs), JCL procedures, and INCLUDE groups. Student will learn to:
- Define GDG indexes and model dataset control
blocks. - Code DD statements to use existing GDG
generations and create new generations. - Use ISPF and IDCAMS facilities to manage GDGs.
- Code in‑stream procedures, cataloged procedures,
and INCLUDE groups. - Use procedures and include members in batch
jobs. - Specify private JCL libraries to contain the
procedures and INCLUDE groups. - Customize procedures and INCLUDE groups with
symbolic parameters. - Code DD and EXEC procedure overrides.
- Perform condition checking via the COND JCL
parameter and IF/ENDIF JCL statements. - Code the OUTPUT JCL statement.
Students will also learn how to use such utility programs as DFSORT, IEBGENER, IEFBR14, and IDCAMS.
A series of written and lab exercises will be used to reinforce the classroom
education.
Audience
Programmer, analysts, technical support personnel, operators and managers working in a z/OS environment.
Prerequisites
A basic understanding of data processing concepts from previous experience (any
