NARS: Difference between revisions

[[STSC]]'s '''APL*PLUS Nested Arrays System''' (acronymized '''NARS''', from "Nested Array Research System") was the first commercial [[Nested array model|nested]] APL implementation. Drawing on work by [[Jim Brown]], [[Trenchard More]], and development manager [[Bob Smith]], NARS introduced a new set of functions for working with arrays that contain arrays, as well as many new operators such as [[Power (operator)|Power]].<ref name="manual">Carl M.
