!!!WSFN (Which Stands for Nothing) ; Copyright (C) 1981 Atari, Inc. and Harry B. Stewart
WSFN (Which Stands for Nothing) was a programming language for controlling robots created by Li-Chen Wang and published by Dr. Dobb's Journal in September 1977. It was later translated into Japanese and published by ASCII.\\
\\
Extended WSFN was an implementation created for the Atari 8-bit family of home computers by Harry B. Stewart and published by the Atari Program Exchange (APX) in 1981. Extended WSFN was designed as 'beginner's language with emphasis on graphics' and included turtle graphics. It was an exceedingly cryptic language.
