ABCL is a family of Actor-Based Concurrent Languages, developed in Japan in the 1980s and 1990s.

ABCL/1

ABCL/1 (Actor-Based Concurrent Language) is a prototype-based concurrent programming language for the ABCL MIMD system, created in 1986 by Akinori Yonezawa, of the Department of Information Science at the University of Tokyo.

ABCL/1 uses asynchronous message passing among objects to achieve concurrency. It requires Common Lisp. Implementations in KCL and Symbolics Lisp are available from the author.

ABCL/R

ABCL/R is a reflective subset of the ABCL/1 programming language, written by Professor Akinori Yonezawa of Tokyo Institute of Technology in 1988.

ABCL/R2

ABCL/R2 is a second generation version of the object-oriented reflective concurrent programming language ABCL/R, designed for the Hybrid Group Architecture.

ABCL/R2 was produced by at the Tokyo Institute of Technology in 1992, and has almost all the functionality of ABCL/1. It is written in Common Lisp.

Since ABCL/R2 is a reflective language, ABCL/R2 programs can dynamically control their behaviour, including scheduling policy, from within a user-process context.

ABCL/c+

ABCL/c+ is an object-oriented concurrent programming language, a variation of ABCL/1 based on C instead of LISP.
