A refreshing antidote to heavy theoretical tomes, this book is a concise, practical guide to modern compiler design and construction by an acknowledged master. Readers are taken step-by-step through each stage of compiler design, using the simple yet powerful method of recursive descent to create a compiler for Oberon-0, a subset of the author's Oberon language. The hands-on, pragmatic approach makes the book equally attractive for project-oriented courses in compiler design and for software engineers wishing to develop their skills in system software. A disk provided with the book gives full listings of the Oberon-0 compiler and associated tools. There is a bug in the installation of this disk, to correct please do the following: *Open the file install.inf in a text editor (e.g. Notepad), this file is found in the win_sys directory. *Scroll down until you find a section marked (files), this is the second last section and is very close to the bottom of the file. *Find the line readme.wri =$I, 9000,0,Information on Oberon, 0,0 and change it so that it reads readme.txt =$I, 9000,0,Information on Oberon, 0,0
