ABCL/1

<language> An Object-Based Concurrent Language.

The language for the ABCL MIMD system, written by Akinori Yonezawa <matsu@is.s.u-tokyo.ac.jp> of Department of Information Science, Tokyo University in 1986. ABCL/1 uses asynchronous message passing to objects. It requires Common Lisp. Implementations in KCL and Symbolics Lisp are available from the author.

ABCL/R2

<language> An object-oriented, concurrent, reflective language based on Hybrid Group Architecture. ABCL/R2 was produced by <masuhara@is.s.u-tokyo.ac.jp>, <matsu@is.s.u-tokyo.ac.jp>, <takuo@is.s.u-tokyo.ac.jp>, <yonezawa@is.s.u-tokyo.ac.jp>, at the Tokyo Institute of Technology in 1992.

As a reflective language, an ABCL/R2 program can dynamically control its own behaviour, such as scheduling policy, from within a user-program. This system has almost all functions of ABCL/1 and is written in Common Lisp.
