Programming Language Processors

Introducing methods for implementing programming languages, David Watt shows how to write simple compilers and interpreters, relating these clearly to the syntax and semantics of the source language. qpa Following a top-down approach, the illustrated text, which contains a working compiler and interpreter for a small programming language, starts by viewing compilers and interpreters as "black boxes", then goes on to examine their working in more and more detail. There is a full exploration of the relationship of syntactic analysis to the source language's syntax, and the relationship of code generation and interpretation to its semantics.
