PL/1 Programming

Code: PL1P

Description

The course not only covers the syntax of all the main PL/1 statements, but also gives attendees a great start for using PL/1 confidently, correctly and efficiently.

Frequent exercises are used to consolidate all the major topics covered. The final exercise builds up to a small but complete and well structured program.

Audience

This course is for experienced programmers who will be coding or maintaining PL/1 applications.

New programmers who require an introduction to PL/1 concepts and rules will also benefit.

The course is designed for the IBM Enterprise PL/1 compiler.

Prerequisites

Delegates should have been introduced to basic data processing concepts and IBM zSeries Orientation before attending this class.

Programming, program design, program edit and job submission knowledge are also necessary.

Objectives

Upon successful completion of this course delegates will be able to:

  • Demonstrate a thorough grounding in the fundamentals of PL/1 programming.
  • Write a typical PL/1 program using well-structured and efficient code.
  • Compile, test and debug their programs.
