Focusing on top-down, modular programming concepts, this Second Edition of the popular text shows readers how to write structured RPG programs for easy code development and maintenance.
Combining the features of a text and a workbook, this guide presents in-depth coverage of the``Report Program Generator'' language. The first text to treat the new capabilities of RPG and to include on-line, real-time applications in RPG III. Presents the RPG logic cycle and gives students practice in debugging--locating and correcting errors in programs or program fragments.
Study Guide to Accompany Computer and Data Processing provides information pertinent to the fundamental aspects of computers and computer technology. This book presents the key benefits of using computers. Organized into five parts encompassing 19 chapters, this book begins with an overview of the evolution of modern computing systems from the earliest mechanical calculating devices to microchips. This text then introduces computer hardware and describes the processor. Other chapters describe how microprocessors are made and describe the physical operation of computers. This book discusses as well how computers present their outputs and explains the storage and retrieval of massive amounts of computer-accessible information from secondary storage devices. The final chapter discusses the use of computers in the transportation systems and the ways in which they make possible other innovations in transportation. This book is a valuable resource for computer scientists, systems analysts, computer programmers, mathematicians, historians, computer specialists, and students.
Application development is a key part of IBM® i businesses. The IBM i operating system is a modern, robust platform to create and develop applications. The RPG language has been around for a long time, but is still being transformed into a modern business language. This IBM Redbooks® publication is focused on helping the IBM i development community understand the modern RPG language. The world of application development has been rapidly changing over the past years. The good news is that IBM i has been changing right along with it, and has made significant changes to the RPG language. This book is intended to help developers understand what modern RPG looks like and how to move from older versions of RPG to a newer, modern version. Additionally, it covers the basics of Integrated Language Environment® (ILE), interfacing with many other languages, and the best tools for doing development on IBM i. Using modern tools, methodologies, and languages are key to continuing to stay relevant in today's world. Being able to find the right talent for your company is key to your continued success. Using the guidelines and principles in this book can help set you up to find that talent today and into the future. This publication is the result of work that was done by IBM, industry experts, business partners, and some of the original authors of the first edition of this book. This information is important not only for developers, but also business decision makers (CIO for example) to understand that the IBM i is not an 'old' system. IBM i has modern languages and tools. It is a matter of what you choose to do with the IBM i that defines its age.
This introduction to structured programming using Turbo Pascal version 5 on the IBM-PC looks at structured programming, the programming sequence, top-down analysis and hierarchy, modular programs, flowcharts and pseudocode, control structures, structured code and how to build a module.
