内容説明

A guide to top-down structured programming that shows how to apply syntax learning and theoretical logic design strategies to everyday programming situations in commercial and business environments. Provides a tool box of design techniques for developing programs that are accurate and easily modified, and offers more than 20 summarized program design templates, standard building blocks from which the majority of business data processing programs are created. These include generic patterns for control break reporting, table loading, internal sorting, sequential add/change/delete up-date, and random access file handling and also includes a reference summary with examples for IBM's new sorting utility, DFSORT; extended examples of both partial key random access to non-IBM random files and to IBM VSAM files; and a comprehensive reference summary with prescriptive actions for all IBM VSAM file status values.
