The Experimental Compiling System (ECS) described here represents a new compiler construction methodology that uses a compiler base which can be augmented to create a compiler for any one of a wide class of source languages. The resulting compiler permits the user to select code quality ranging from highly optimized to interpretive. The investigation is concentrating on easy expression and efficient implementation of language semantics; syntax analysis is ignored.
