About the book:

Learning CL programming just got easier! That's because Greg Veal has updated his 1992 best-selling book, CL Programming for the AS/400--Second Edition for V4R3 with a comprehensive new chapter on CL in the Integrated Language Environment. Additionally, each chapter includes comparisons of the important concepts from the OPM and ILE perspective. Learning the material will be easy as you progress through the more advanced concepts using examples of real-world programs just like those that support user applications and system operations in many companies. In addition, review questions at the end of each chapter will allow you to self-test your knowledge. An optional instructor's guide with progressive lab assignments, exercise hints, and sample solutions is also available.
