LISP and APL2 were both born in 1960's and they have the similar syntax which is called function type. The main users of LISP were in the universities and the applications were linguistics or formula processing in mathematics. On the other hand APL was used in the companies and many of their applications were in the business environment such as business planning or reporting. Traditional APL provided user intuitive expressions, but it was rather weak in handling character string of variable length or combination of numerics and characters. APL2 and its general array resolved these weak points and it has a great capability to develop AI applications. This paper introduces the similarities between LISP and APL2 and shows how APL2 solves the problem which LISP is good at handling.
