RefLisp
<language> A
Lisp interpreter by Bill Birch of
Bull, UK, with shallow-binding and
dynamic scope.
Use of
reference counting makes it suitable for experimenting with
real-time and
graphical user interfaces.
Common Lisp compatibility
macros are provided, and most of the examples in "Lisp" by Winston & Horn have been run on RefLisp.
RefLisp makes no distinction between symbol-values and function-values, so a symbol can be either but not both.
There are Lisp
modules for
lexical scope and for running indefinite extent {Scheme} programs.
Version 2.67 ("Last Update for a While", the author is emigrating to Australia) includes an interpreter, documentation, examples and a profiler.
It runs under
MS-DOS (
CGA/
EGA/
VGA) and
AIX.
