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}. (ftp://camille.is.s.u-tokyo.ac.jp/pub/abclr2/). (1993-01-28)
