Structured Programming with COBOL Examples


Book Description

As the conversion of legacy systems continues, the ability to understand embedded business rules becomes more and more critical. This ability is directly related to the structure of the programs within those systems. We also see the need to teach structured programming to a new generation of programmers who must maintain the billions of lines of existing COBOL code. The ultimate purpose of this text is to discuss how to judge the level of structure of a program. We do this by defining structured programming and then discussing how a structured program can be built through the application of the concepts of coupling and cohesion. We also show how embedded business rules of the program can be separated from the data and presentation functions. The reader will be able to use to these skills to judge and to improve the structure of a new program or an existing program.




Advanced ANSI COBOL with Structured Programming


Book Description

Explains COBOL as it exists in the new ANSI standard. Designed for advanced programmers, it eases the transition from general programming training to the programming done in business applications using COBOL. Through hundreds of practical examples, it explores the intricacies of COBOL without spending a lot of time on basic computer concepts. With an emphasis on cross-system application and development, it describes both IBM's VS COBOL II for the mainframe environment and Microsoft's COBOL for the personal computer.




A Simplified Guide to Structured COBOL Programming


Book Description

This is for the person who wants to learn what COBOL is, what programming is, and how to use COBOL in typical business data processing applications. Assumes no previous background in programming. Hands-on programming begins in Chapter 1--each chapter is based on one or more example programs applicable to real-life business settings. Treatment is based on the concepts of structured programming--only a few logical control structures are used throughout the book. Emphasizes a clear program style for ease of reading and debugging. All programs have been tested and run, and computer output is displayed in each case.

Murach's Mainframe COBOL


Book Description

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.

Beginning COBOL for Programmers


Book Description

Beginning COBOL for Programmers is a comprehensive, sophisticated tutorial and modular skills reference on the COBOL programming language for established programmers. This book is for you if you are a developer who would like to—or must—add COBOL to your repertoire. Perhaps you recognize the opportunities presented by the current COBOL skills crisis, or are working in a mission critical enterprise which retains legacy COBOL applications. Whatever your situation, Beginning COBOL for Programmers meets your needs as an established programmer moving to COBOL. Beginning COBOL for Programmers includes comprehensive coverage of ANS 85 COBOL features and techniques, including control structures, condition names, sequential and direct access files, data redefinition, string handling, decimal arithmetic, subprograms, and the report writer. The final chapter includes a substantial introduction to object-oriented COBOL. Benefiting from over one hundred example programs, you’ll receive an extensive introduction to the core and advanced features of the COBOL language and will learn to apply these through comprehensive and varied exercises. If you've inherited some legacy COBOL, you’ll be able to grasp the COBOL idioms, understand the constructs, and recognize what's happening in the code you’re working with. Today’s enterprise application developers will find that COBOL skills open new—or old—doors, and this extensive COBOL reference is the book to help you acquire and develop your COBOL skills.




Introduction to COBOL


Book Description

"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. .
