SETL Implementation: Data Structures, Primitives, and Storage Management

Abstract

This paper discusses the implementation of the SE’TL language on the CDC 6600 computer. SETL is a very high level language that is currently being developed at New York University. Two important properties of SETL are its lack of data declaration statements and its inclusion of the unordered set as a data type. The following are described: I. An existing preliminary implementation. 2. The LITTLE systems programming language, upon which the next SETL implementation is based. 3. Encoding of data. 4. Minimizing data copying. 5. Run time stack management. © 1974, Taylor & Francis Group, LLC. All rights reserved.
