The original Lisp. Invented by John McCarthy et al at MIT in the late 50’s. Followed by LISP 1.5.
- Lisp 1.5
The second version of Lisp, successor to LISP 1. Developed at MIT in 1959. Followed by LISP 1.75, LISP 1.9, Lisp 2 and many other versions.
- Lisp 2
LISP 1.5 with an ALGOL 60-like surface syntax. Also optional type declarations, new data types including integer-indexed arrays and character strings, partial-word extraction/insertion operators and macros. A pattern-matching facility similar to COMIT was proposed. Implemented for the Q-32 computer. [“The LISP 2 Programming Language and System”, P.W. Abrahams et al, Proc FJCC 29:661-676, AFIPS (Fall […]
A Lisp dialect descended from MLISP and MLISP2. Also known as PLISP and VEL. Useful for parsing. Only the pattern-matching system was published and fully implemented. According to Alan Kay, LISP70 had an influence on Smalltalk-72. “The LISP70 Pattern Matching System, Larry Tesler et al, IJCAI 73.
