Introduction To Computer Programming Structured Cobol

Introduction to computer programming structured COBOL

Introduction to COBOL

"Ideal for readers with little programming and/or mathematical background, this practical introduction to Cobol programming uses a simplified, "learn-by-example" approach that stresses top-down design and modular structured programming and emphasizes the planning and development of the program logic throughout - with complete programming examples that walk users through the problem analysis, logic design, program coding, testing, and debugging." Introduces two or more realistic sample programs in each chapter which demonstrate application of the program development process to an actual programming situation "from start to finish" - covering everything from problem definition to input/output specifications, processing requirements, hierarchy charts, program flowcharts, pseudocode, and program code. Stresses the importance of using top-down logic design and modular structure programming to construct high-quality, easy-to-read programs. Dissects program code and explains "step-by-step" how the program statements work together to produce the desired output. Examines menu-driven programming, data validation, guidelines for creating efficient and effective menu systems, and sequential, relative and indexed files. Checkpoint exercises, chapter summaries, and programming projects are included." For electronic and computer technology professionals. .

Murach's Mainframe COBOL

This is the latest edition of our classic COBOL book that has set the standard for structured design and coding since the mid-1970s. So if you want to learn how to write COBOL programs the way they're written in the best enterprise COBOL shops, this is the book for you. And when you're done learning from this book, it becomes the best reference you'll ever find for use on the job. Throughout the book, you will learn how to use COBOL on IBM mainframes because that's where 90% or more of all COBOL is running. But to work on a mainframe, you need to know more than just the COBOL language. That's why this book also shows you: how to use the ISPF editor for entering programs; how to use TSO/E and JCL to compile and test programs; how to use the AMS utility to work with VSAM files; how to use CICS for developing interactive COBOL programs; how to use DB2 for developing COBOL programs that handle database data; how to maintain legacy programs. If you want to learn COBOL for other platforms, this book will get you off to a good start because COBOL is a standard language. In fact, all of the COBOL that's presented in this book will also run on any other platform that has a COBOL compiler. Remember, though, that billions of lines of mainframe COBOL are currently in use, and those programs will keep programmers busy for many years to come.
