The CWIC/36O system, a compiler for writing and implementing compilers
Erwin Book, Dewey Val Shorre, Steven J. Sherman · ACM SIGPLAN Notices · 1970
Cwic/360 (Compiler for Writing and Implementing Compilers) is a metacompiler system. It is composed of compilers for three special-purpose languages, each intended to permit the description of certain aspects of translation in a straightforward, natural manner. The Syntax language is used to describe the recognition of source text and the construction from it of an intermediate tree structure. The Generator language is used to describe the transformation of the tree into appropriate object language. The MOL/360 language is used to provide an interface with the machine and its operating system.This paper describes each of these languages, presents examples of their use, and discusses the philosophy underlying their design and implementation.
