OS/390 MVS JCL Advanced
This advanced course introduces techniques to increase your effectiveness as a system user and JCL programmer. Learn how to use addition, override, and nullification statements to enable procedures to be modified at execution time to meet particular processing needs. Reduce JCL coding by using symbolic parameters, DDNAME operands, and other coding techniques. The course also introduces utility programs and the JCL required to communicate with utilities. Learn to analyze condition codes and system error messages that explain JCL and utility control statement errors. Learn a problem-solving approach for determining what JCL and utility control statements are required for common processing situations.
MVS JCL Advanced training covers such topics as:
Reviewing Procedures
Creating Effective Procedures
Using Utility Programs
Sample Utility Applications
This course is designed for intermediate to advanced JCL system programmers,
operators, and application programmers with some knowledge of basic JCL coding
Description
This course builds and extends the skills and knowledge developed
in the OS/390 MVS JCL
Introduction and Intermediate courses (38053, 38054). This advanced
course introduces techniques
to increase effectiveness as a system user and JCL programmer.
The course reviews and extends
basic concepts and skills related to the use of procedures. A review
of addition, override, and
nullification statements that enable procedures to be modified
at execution time to meet particular
processing needs is included in this course. The course also examines
procedures from the
perspective of the procedure creator. The emphasis is on the effective
use of symbolic parameters,
DDNAME operands, and other coding techniques that can relieve the
procedure user of the need
for extensive JCL coding. Utility programs and the JCL required
to communicate with utilities are
also introduced in this course. Other coverage includes analyzing
condition codes and system error
messages that provide clues to the cause of JCL and utility control
statement errors. Finally, the
course shows what a range of practical applications can be achieved
with utilities. The course
adopts a problem-solving approach in determining the JCL and utility
control statements that are
required for common processing situations. This course is written
to OS/390 version 2.x.
Audience
This course is designed for intermediate to advanced JCL system
programmers, operators, and
application programmers with some knowledge of basic JCL coding.
