ABCL/1

<language> An Object-Based Concurrent Language.

The language for the ABCL MIMD system, written by Akinori Yonezawa <[email protected]> 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 <[email protected]>, <[email protected]>, <[email protected]>, <[email protected]>, 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.
