|(language)||Stanford Artificial Intelligence Language - (SAIL) Dan Swinehart & Bob Sproull, Stanford AI
Project, 1970. A large ALGOL 60-like language for the DEC-10
and DEC-20. Its main feature is a symbolic data system based
upon an associative store (originally called LEAP). Items may
be stored as unordered sets or as associations (triples).
Processes, events and interrupts, contexts, backtracking and
record garbage collection. Block- structured macros. "Recent
Developments in SAIL - An ALGOL-based Language for Artificial
Intelligence", J. Feldman et al, Proc FJCC 41(2), AFIPS (Fall
1972). (See MAINSAIL).|
The Stanford Artificial Intelligence Language used at SAIL (the place). It was an ALGOL 60 derivative with a coroutining facility and some new data types intended for building search trees and association lists.
A number of interesting software systems were coded in SAIL, including early versions of FTP and TeX and a document formatting system called PUB.
In 1978, there were half a dozen different operating systems for the PDP-10: WAITS (Stanford), ITS (MIT), TOPS-10 (DEC), CMU TOPS-10 (CMU), TENEX (BBN), and TOPS-20 (DEC, after TENEX).
SAIL was ported from WAITS to ITS so that MIT researchers could make use of software developed at Stanford University. Every port usually required the rewriting of I/O code in each application.
