Introduction: MVS
JCL is a language full of pitfalls, ambiguities, gray areas and events
that often defy logic. For every rule there seemingly, is at least
one exception. The documentation provides little or no explanations.
Even people using JCL on a daily basis for many years have areas that
can be refreshed or enhanced. There are new portions of JCL that can
make the JCL user more effective.
This course focuses on those parts of JCL which will satisfy
most, if not all, of the needs of the MVS JCL user. The
course author and instructor have been using JCL for 25
years.
Audience: Programmers, system programmers, end-users,
analysts, technical support specialists, or operators who
have a need to submit batch work in an MVS system or need to
debug JCL.
Objectives: Upon completion of this session, the
student should be able to:
- State when MVS will
alter or ignore submitted JCL
- Given return codes from
previous steps, state what a step will do when a specific
COND parameter is specified.
- State three DASD space
considerations.
- List the steps involved
in taking a job from submission to termination.
- Create instream and
catalogued JCL procedures
- Override parameters and
control statements in JCL procedures
- Use the
IF/THEN/ELSE/ENDIF construct to create conditional step
logic
- Identify the impact of
system-managed storage on JCL
- Use installation-defined
SMS constructs in a job stream
Prerequisites: The student must be a JCL user.
Duration:
This course is
3 days long.
