Understanding and Writing Compilers: A Do It Yourself Guide (repost)

This book attempts to explain and demystify the principles of compiler writing so that you can go out and build a working compiler of your own. There is enough detail in this book for you to build a compiler for quite a complicated language { certainly PASCAL, perhaps ALGOL 68 or SIMULA 67 { but it doesn't attempt an encyclopaedic coverage of the eld. It is intended more as an introduction to compiler-writing and a do-it-yourself kit for the compiler-writer, giving enough detail for you to understand the principles of the subject, than as a survey of past history or present horizons. The principles of interpretation are close enough to those of compilation for chapter 19 to give a simple introduction to interpreter writing.
