CL Programming for the AS/400--2nd edition

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. Whether for self-study or formal classroom education, CL Programming for the AS/400--Second Edition is the perfect resource for learning CL programming. This book will teach you how to: write and compile CL programs, code complex character string expressions using CL program variables,use the substring built-in function and concatenation operators, code arithmetic expressions, understand and code logical and relational expressions, write structured code using GOTO with IF and ELSE, avoid parameter passing pitfalls with SBMJOB, send and receive messages in CL programs, write error-handling logic for expected and unexpected exceptions, use advanced message-handling techniques, including break-handling programs, sender data interpretation, and message data interpretation, develop generalized, modular error-handling programs, develop structured CL programs for supporting user applications, develop sophisticated CL programs for supporting system operations, process outfiles and other database files in CL programs, use OPNQRYF to process database files, use display files with message subfiles in CL programs, and more!
