- LISP 2
:"For Lisp-2, Lisp systems with separate function namespaces, see Lisp-1 vs. Lisp-2"
LISP 2 was a
programming language proposed in the 1960s as the successor to Lisp. It had largely Lisp-like semantics and Algol 60-like syntax. Today it is mostly remembered for its syntax, but in fact it had many features beyond those of early Lisps.Early Lisps had many limitations, including limited data types and slow numerics. Its use of fully-parenthesized notation was also considered a problem. The inventor of Lisp, John McCarthy, expected these issues to be addressed in a later version, called notionally Lisp 2. Hence the name Lisp 1.5 for the successor to the earliest Lisp. [McCarthy, 1979]
Lisp 2 was a joint project of the
System Development Corporation andInformation International, Inc. , and was intended forIBM 'sAN/FSQ-32 military computer. Development later shifted to the IBM 360/67 and the Digital Equipment CorporationPDP-6 . The project was eventually abandoned.Bibliography
