Interlisp

A dialect of Lisp developed in 1967 by Bolt, Beranek and

Newman (Cambridge, MA) as a descendant of BBN-Lisp. It

emphasises user interfaces. It is currently supported by

Xerox PARC.

Interlisp was once one of two main branches of LISP (the other

being MACLISP). In 1981 Common LISP was begun in an

effort to combine the best features of both. Interlisp

includes a Lisp programming environment. It is dynamicallyscoped. NLAMBDA functions do not evaluate their arguments.

Any function could be called with optional arguments.
