(HMSL) A programming language for experimeNTal music composition and performance. It is a set of object-orieNTed extensions to Forth. (Its near-total uniNTelligibility to people unfamiliar with Forth has led some to expand "HMSL" as "Her Majesty' s Secret Language".) Phil Burk (who also later developed pForth), Larry Polansky, and David Rosenboom started developing HMSL in 1980 while working at the {Mills College CeNTer for CoNTemporary Music (http://www.mills.edu/LIFE/CCM/CCM.homepage.html)}. As of June 1998, developmeNT is ongoing. . (1998-09-07)
