A dialect of
Lisp developed at
MIT AI Lab in
1966, known for its efficiency and programming facilities.
MacLisp was later used by
Project MAC,
Mathlab and
Macsyma. It ran on the
PDP-10. It introduced the LEXPR
(a function with variable
arity), macros, arrays, and
CATCH/THROW.
MacLisp was one of two main branches of LISP (the other being
Interlisp). In 1981
Common LISP was begun in an effort to
combine the best features of both.
