Abstract-Type and Scheme-Definition Language

Abstract-Type and Scheme-Definition Language (ASDL) was a computer language developed as part of Esprit[?] project GRASPIN[?], as a basis for generating language-based editors and environments. It combines an object-oriented type system, syntax-directed translation[?] schemes and a target-language interface[?].
