St Andrews Static Language

St Andrews Static Language

(language)(SASL) A functional programming language designedby Professor David Turner in 1976 whilst at St. AndrewsUniversity. SASL is a derivative of ISWIM with infinite data structures. It is fully lazy but weakly typed. Itwas designed for teaching functional programming, with verysimple syntax.

Example syntax:

def fac n =n = 0 -> 1 ; n x fac(n-1)

A version of the expert system EMYCIN has been written inSASL.

SASL was originally known as "St Andrews Standard Language".Not to be confused with SISAL.
