Nial (from "Nested Interactive Array Language") is a high-level array programming language developed from about 1981 by Mike Jenkins of Queen's University, Kingston, Ontario, Canada. Jenkins co-created the Jenkins–Traub algorithm. Nial combines a functional programming notation for arrays based on an array theory developed by Trenchard More with structured programming concepts for numeric, character and symbolic data.
