Alphard is a Pascal-like programming language for data abstraction and verification, proposed and designed by William A. Wulf, Ralph L. London, and Mary Shaw.[1] The language was the subject of several research publications in the late 1970s, but was never implemented. Its main innovative feature was the introduction of the 'form' datatype, which combines a specification and a procedural (executable) implementation. It also took the generator from IPL-V,[2] as well as the mapping functions from Lisp[3] and made it general case.[4]
