ABCL/R Takuo Watanabe Department of Information Science, The Univ. of Tokyo ABCL/R is a reflective subset of the object-oriented concurrent language ABCL/1. The language processor of ABCL/R is written in ABCL/1. Currently, the processor runs ABCL/R program fully interpretively --- it is very SLOW ---. (I'll not support this version anymore.) We are now working on much faster version of ABCL/R2, which will directly run on Common-Lisp (without ABCL/1) and supports shared memory machine LUNA-88K.
