Data abstraction in GLISP

Abstract

GLISP is a high-level language that is based on Lisp and is compiled into Lisp. It provides a versatile abstract-data-type facility with hierarchical inheritance of properties and object-centered programming. The object code produced by GLISP is optimized, so that it is about as efficient as handwritten Lisp. An integrated programming environment is provided, including editors for programs and data-type descriptions, interpretive programming features, and a display-based inspector/editor for data. GLISP is fully implemented.
