WSFN (programming language)
WSFN (Which Stands for Nothing) was a programming language for controlling robots created by Li-Chen Wang[1] and published by Dr. Dobb's Journal in September 1977.[2] It was later translated into Japanese and published by ASCII.[1]
Extended WSFN was an implementation created for the Atari 8-bit family of home computers by Harry Stewart, and published by the Atari Program Exchange[3] in 1981.[4] Extended WSFN was designed as "beginner's language with emphasis on graphics"[5] and included turtle graphics[citation needed].
It was an exceedingly cryptic language. For example, this is a program to draw Sierpiński curves:
