CSSA: Language concepts and programming methodology

Abstract

CSSA (Computing System for Societies of Actors) is an experimental programming language that originated from an attempt to design a language combining various new ideas having evolved from the fields of semantics of programming languages, artificial intelligence, programming methodology, and language design in recent years: (1) Abstraction semantics improving denotational semantics by describing the semantics of programming language constructs uniformly in terms of operational abstractions [1,2]. (2) Some features of CSSA have been inspired by the actor concept of PLASMA [3].(3) Programming in terms of control and data abstractions. (4) Heirarchical control structures (dynamic generation and manipulation of actor nets). (5) Definable access operations and access control to shared data [4]. (6) Data driven and goal directed computation.
