Synopsis
Since its introduction in 1993, Control Language Programming for the AS/400 has been an integral part of hundreds of AS/400 college courses. The textbook has been a boon to students who plan to initiate careers as AS/400 programming professionals, as well as a must-read reference for programmers already in the workplace.Now Dan Riehl, Bryan Meyers, Jim Buck have updated this classic text with the publication of Control Language Programming for IBM i. This new book builds upon the success of the original text but brings it up to date with the IBM i 6.1 release for Power systems. The text covers all the basics as well as the latest CL features — including new structured programming capabilities, file processing enhancements, and the Integrated Language Environment (ILE).Students without previous knowledge of CL will learn the basics quickly. As the book progresses methodically to more complex processes and concepts, it guides readers smoothly toward a professional grasp of CL programming techniques and style. Review questions and hands-on exercises and programming assignments reinforce each chapter's content. Professional programmers will also find this book useful as a daily CL reference. In additional to 25 chapters covering CL from start to finish, a comprehensive appendix serves as a condensed reference to the CL commands used most often in CL programs. Two other appendices cover the essentials of programming tools and debugging.INTRODUCTION TO CONTROL LANGUAGE 1. What is CL? 2. Control Language Command Names 3. Command Parameters 4.
