Structured COBOL Programming for the AS400

A new revision of the only COBOL text to focus on COBOL/400 as usedon AS/400 and iSeries Server platforms, PROGRAMMING INCOBOL/400, SECOND EDITION emphasizes developing strong designand programming techniques as well as mastering COBOL/400. The newedition features expanded coverage of ILE COBOL and subfiles, andall program dates and database data fields are Y2K compliant.

Whether you are an experienced programmer acquiring a newlanguage or never have programmed before, PROGRAMMING INCOBOL/400 will help you:

Design COBOL/400 programs that are easy to read, debug,modify, and maintain. Understand the theory and the practice behind writingCOBOL/400 programs. The authors blend theory, practical caseproblems, and working examples in each chapter, so you see howCOBOL/400 works from all angles. Complete structured programming examples that you canuse. Every chapter of PROGRAMMING IN COBOL/400 includescomplete programming in their entirety that you can use as a guidein developing your own applications. Practice programming. PROGRAMMING IN COBOL/400 includesa wealth of  practice problems, ranging from basic definitionsand short answers to larger problems that teach you to writestructured programs in their entirety. Check your work on selectedproblems and programs against answers in the Appendices.
