Introduction to Turbo Pascal [antikvár]

Introduction This book was written to help readers develop, as quickly as possible, the ability to write problem-solving programs in Turbo Pascal. It should also help readers develop an understanding of structured programming along the way Existing books on Pascal do not address the unique facets of Turbo. Turbo's extensions and nonstandard features are not mere minor syntactical variations. In Turbo Pascal, Borland has grafted a huge set of extensions and simplifications onto the elegant framework of Niklaus Wirth's theoretical Pascal. Standard Pascal, and the books describing it, mirror the technology that spawned Pascal. The language was originally developed in an academic world using large, batch-oriented, time-sharing computers. The unheard-of power and availability of personal computers shattered many of the restraints of earlier Pascals, and permitted the unprecedented innovations of Turbo. This purely Turbo-oriented, hands-on guide was written to help more people take advantage of these unique innovations. The capabilities of Turbo are too powerful to be ignored, too elegant to be buried in obscure documentation, and too capable to be left entirely to frustrating trial and error. Moreover, Turbo's blending of standard features, universal extensions, and further machine-dependent features is a triumph of consistency and user-friendliness. Some other PC-based Pascals have earned the unfortunate reputation of being merely "grouchy BASIC." No description could be more inaccurate for Turbo, and we hope this book shows just how easy to learn and user-friendly Turbo is. This book does not have syntax diagrams nor an appendix of Backus-Naur Form expressions. Turbo is a uniquely approachable language and the author refuses to put academic hurdles in the way
