Sinossi
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. .
