A PL/I Primer - Student Text

IBM, 1965. — 72 p.The purpose of this publication is to provide tutorial material not only for the person with some knowledge of computer programming but also for the novice who knows little or nothing about data processing.The first chapter is written solely for the novice. A reader who is familiar with basic programming techniques should skip the first chapter, and begin reading Chapter 2, «Basic Elements of PL/I."Chapter 1, "Communicating with a Computer," touches on machine language and introduces the concept of symbolic programming. The basic techniques of programming are illustrated by using symbolic instructions, rather than PL/I because certain PL/I statements can generate so much single-instruction coding that the details of some of the techniques are hidden.
