<language> (CMU CL) A public domain "industrial strength" Common Lisp programming environment. Many of the X3J13 changes have been incorporated into CMU CL. Wherever possible, this has been done so as to transparently allow use of either CLtL1 or proposed ANSI CL. Probably the new features most interesting to users are SETF functions, LOOP and the WITH-COMPILATION-UNIT macro. The new CMU CL compiler is called Python. Version 17c includes an incremental compiler, profiler, run-time support, documentation, an editor and a debugger. It runs under Mach on SPARC, MIPS and IBM PC RT and under SunOS on SPARC. lisp-sun1.slisp.cs.cmu.edu/pub/">ftp://lisp-sun1.slisp.cs.cmu.edu/pub/. E-mail: <slisp@cs.cmu.edu>. (1993-11-18)

CMU Common Lisp

<language> A dialect of Lisp defined by a consortium of companies brought together in 1981 by the {Defence Advanced Research Projects Agency} (DARPA). Companies included Symbolics, Lisp Machines, Inc., {Digital Equipment Corporation}, Bell Labs., Xerox, Hewlett-Packard, Lawrence Livermore Labs., Carnegie-Mellon University, Stanford University, Yale, MIT and USC Berkeley. Common Lisp is lexically scoped by default but can be dynamically scoped. Common Lisp is a large and complex language, fairly close to a superset of MacLisp. It features lexical binding, data structures using defstruct and setf, closures, multiple values, types using declare and a variety of numerical types. Function calls allow "&optional", keyword and "&rest" arguments. Generic sequence can either be a list or an array. It provides formatted printing using escape characters. Common LISP now includes CLOS, an extended LOOP macro, condition system, pretty printing and logical pathnames. Implementations include AKCL, CCL, CLiCC, CLISP, CLX, CMU Common Lisp, DCL, KCL, MCL and WCL.
