PL/I programming: fundamentals course

In this practical course participants learn to use the PL/I programming language in order to write and maintain applications in PL/I. The participants will learn to write, test and execute programs.

After having followed this course:

  • participants know the complete PL/I syntax;
  • participants are able to develop, to debug and to execute PL/I programs in a z/OS environment.

The debugging and interpretation of compilation listings is also explained.

Schedule

No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please contact ABIS.

Intended for

Programmers who want to write PL/I programs.

Background

Participants should have some programming experience or otherwise have followed the course Programming fundamentals). Some familiarity with the TSO/ISPF environment is required (see course ISPF/PDF basics).

Main topics

  • General introduction:

History - PL/I program: first introduction

  • Different aspects of PL/I:

Declaration of data elements

Complex data structures

RECORD input/output

Program flow: DO WHILE/UNTIL, IF THEN .... ELSE, SELECT

External and internal subroutines

Function manipulation

Exception handling

Treatment of files for input and output (sequential files)

  • Compiler and Linker options - Run:

The complete application development cycle from Source to Load Module is treated, some attention is given to the PL/I compiler and the Linkage Editor. The most frequent compiler options are discussed.

The execution stage including guide lines for testing and debugging are treated in detail.
