Introduction to COBOL : A Guide to Modular Structured Programming

0.0

For freshman/sophomore level introductory courses in computer programming, such as Programming and Design, Introduction to COBOL Programming, Introduction to Business Programming, and Introduction to Computer Science. Light on technical lingo and free of extraneous details, this carefully crafted introductory text presents COBOL at a level new students will enjoy and readily understand, using a simplified, “learn-by-example” approach that stresses top-down design and modular structured programming. Placing a special emphasis on planning and developing the program logic, it offers complete programming examples that walk students through the problem analysis, logic design, program coding, testing, and debugging, and examines sequential and indexed file processing in an easy-to-follow, step-wise manner.For Sale in Indian subcontinent onlyFeaturesWritten for the beginner. Conversational in tone and easy-to-understand, the text is accessible to anyone who wants to learn to program in COBOL. “Learn-by-example approach” — Introduces two or more realistic sampleprograms in each chapter which demonstrate how the material can be applied to an actual programming situation; illustrates the application of the program development process from start to finish.Program development process— Emphasizes the program development process throughout as a means to teach applications, and stresses the importance of using top-down logic design and modular structure programming to construct high-quality, easy-to-read programs.Program dissections. Dissects program code and explains step-by-step how the program statements work together to produce the desired output.Non-technical coverage of key topics—Offers a simplified yet highly effective study of such important topics as menu-driven programming, data validation, guidelines for creating efficient and effective menu systems, sequential, relative and indexed files, and more.A host of pedagogical aids—Includes checkpoint exercises, chapter summaries, and programming projects.ContentsBasic Concepts.Taking a Closer Look.Modular Programming and Picture Strings.Loops and Printer Output.Decisions and Branching.Using Menus.Using Data Files.Page and Control Break Reports.Multilevel Control Break Reports.Table Processing.Multilevel Tables.Sequential Files.Updating Sequential Files.Relative File Processing.Indexed Files.
