Lieber Interessent, ich schaue alle Bücher hinsichtlich handschriftlicher Einträge, Anstreichungen oder ähnliches durch. Je mehr Seiten ein Buch hat, desto größer ist die Gefahr, dass ich mal etwas übersehe. Es kann allerdings dann nicht sehr viel sein. Sollte das also doch mal passieren, bitte ich um Verständnis und um Entschuldigung.

Introduction

If you counted the number of books available on the PL/I language, you’d probably be astonished. Most are aimed at university - and college-level students, or the programmer dealing mainly in scientific or mathematical applications. The purpose of this book is to give you a simple, practical approach to PL/I, an approach that you can put to practical use almost immediately.
PL/I was designed for use by programmers with applications at any level. This means you only need to learn those features of the language that satisfy your immediate needs. It is not necessary to learn every detail of the language before you put it to use.
From a quick glance through this book (or the Table of Contents) you will see that it covers six areas. First, brief history of PL/I, an introduction to its use, programming and flowcharting, and a simple program are given.
Then, the all important variable, and the character and numeric data in terms of use and input /output are introduced.
From the introduction to program control, starting with simple statements. You will learn several methods of varying execution of statements. Arrays and their use in storing and processing large amounts of data are fully explained and demonstrated. You are introduced to PL/I procedures and funtions.
Finally, the appendices provide useful terms and examples that you will want to refer to frequently - especially if you are new at programming.
It would be extremely helpful if you had some previous instruction in another high-level language prior to studying this book, but it is not necessary. lf this is your first attempt at programming, however, make sure that you understand the material in each chapter before continuing. Reread any section that is not clear and pay close attention to all examples and, if possible, work each one out on a computer as you go over them.
Remember, the modular characteristics of PL/I allow you to explore only those topics necessary for your immediate needs. As you advance, you will surely want to pursue advanced topics to expand your programming capabilities. In the preparation of this book, a deep and grateful bow must be made to those individuals who lent a helping hand. First of all, a special thanks goes to John Traister who encouraged me to write this book and also my family for their understanding during the long hours spent in writing this book. I'm also indebted to Dr. J.A.N. Lee, Dr. Thomas Wesselkamper, and Robert G. Fainter - professors at Virginia Polytechnical Institute - who lead me through many hours of classroom study.
