Good, Maybe a little too focused on one solution.
The book describes step-by-step how the author would write a compiler for PASCAL. It could do with some more explanations of the logic behind some of the decisions,as it tends to quickly explain what the following C++ code does,before launching into pages of (well written) programming. If you have been tasked to write a specific compiler, then this book is probably what you want to get. If you are wanting to further your knowledge of the art, then you would be better looking at some of the more weighty volumes.
