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 Lisp3 and made it general case.4
