The external Syntax iS ALGOL-like and extenSible, Supporting uSer-defined data StructureS, control StructureS and operationS. The parSer iS table-driven, with a modifiable Set of productionS. USed aS the baSiS for the ECL operating SyStem. ["StudieS in ExtenSible Programming LanguageS", B. Wegbreit, Garland. Pub 1980].
