TSO/E CLIST Programming

SEE SCHEDULE

Duration: 5 days

Method: Instructor led, Hands-on workshops

Price: $2475.00

Course Code: MF2001

Audience

Programmer, technical support personnel, and other individuals that need to write CLISTs.

Description

This course will introduce students to the skills necessary to code CLISTs in a z/OS Environment.

A series of written and lab exercises will be used to reinforce the classroom education.

Objectives

Upon successful completion of this course, the student will be able to:

Create and allocate CLIST libraries
Invoke CLISTs and pass parameters to them
Use CLIST instructions to perform terminal I/O
Perform arithmetic calculations and character operations
Use such CLIST programming constructs as: F statements, SELECT WHEN constructs, DO WHILE and iterative DO loop sequences
Debug CLISTs via CONTROL statements
Write user developed CLIST subprocedures
Issue TSO commands from a CLIST
Trap TSO command output and process the output in a CLIST
Use ISPF services
Read and write sequential datasets
Create CLIST based ISPF edit macros
Execute CLISTs in batch jobs

Prerequisites

Introduction to z/OS, or equivalent experience. TSO/ISPF, or equivalent experience. Previous experience in designing and coding application programs will enhance the results of this course.
