from the back cover:"...is a thorough introduction to one of the most talked-aboiut programming languages developed in the last decade. Highly structured, Modula-2 allows the creation of modules, independent program parts that can isolate common program functions and be used to build libraries of programming routines. Modula-2"s structure and access to system-level facilities are invaluable for systems-level programming.Designed by niklaus Wirth to be more fully functional than his earlier language, Pascal, Modula-2 is available for the IBM PC, Apple II, Macintosh, VAX, and other computers. Focusing on the features of Modula-2 that are used mst by programmers, Edward Joyce gives experienced programmer and enthusiastic novices a clear overview of the complete language.Thorough explanations of each command are supplemented by numerous program expamples that allow you quickly to get a feel for the power and structure of Modula-2. In addition, you"ll find:-a quick primer for Pascal programmers-self-study problems in each chapter-numerous program examples: some complete programs, others useful programming tricks-detailed appendices containing a full reference guide to the language and useful program modules-a comparison of Pascal and Modula-2"
