This text is an introduction to programming in general, and a manual for programming with the language Modula-2 in particular. It is oriented primarily towards people who have already acquired some basic knowledge of programming and would like to deepen their understanding in a more structured way. Neveltheless, an introductory chapter is included for the benefit of the beginner, displaying in a concise form some of the fundamental concepts of computers and their programming. The text is therefore also suitable as a self-contained tutorial. The notation used is Modula-2, which lends itself well for a structured approach and leads the student to a working style that has generally become known under the title of structured programming. As a manual for programming in Modula-2, the text covers practically all facilities of that language. Part 1 covers the basic notions of the variable, expression, assignment, conditional and repetitive statement, and array data structure. Together with Palt 2 which introduces the important concept of the procedure or subroutine, it contains essentially the material commonly discussed in introductory programming courses. Part 3 concerns data types and structures and constitutes the essence of an advanced course on programming. Palt 4 introduces the notion of the module, a concept that is fundamental to the design of larger programmed systems and to programming as team work. The most commonly used utility programs for input and output are presented as examples of modules.

Compiler sind mehr als komplexe Programme, deren Herstellung einigen wenigen, großen Firmen vorbehalten bleibt. Sie spielen gewissermaßen die Rolle der Brücke zwischen Software und Programmiersprache einerseits und Hardware und Rechnerarchitektur andererseits. Deshalb ist das Verständnis ihrer Prinzipien und ihrer Struktur für jeden Informatiker wesentlich. Dieses Buch ist aus der Erfahrung erwachsen, dass neue Lehrstoffe nur dann haften bleiben, wenn sich der Leser auch praktisch mit der Materie befasst. Hier ist das zentrale Anliegen daher der Bau eines kompletten Compilers einer einsatzfähigen Programmiersprache und dessen Darlegung in allen Einzelheiten. Dazu wird aufgrund ihres systematischen Aufbaus eine substantielle Untermenge der Sprache Oberon gewählt und als Zielrechner eine RISC-Architektur, wobei beiden exemplarischer Charakter zukommt.

Questions arising out of the Southampton Symposium on Pascal in 1977 [Reference 10] began the first organized effort to write an officially sanctioned, international Pascal Standard. That effort culminated in the ISO 7185 Pascal Standard [Reference 11] which officially defines Pascal and necessitated the revision of this book.
