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.

It was an exceedingly cryptic language. For example, this is a program to draw Sierpiński curves:

DIT(-I2FI5RG5RI2FI+)2R
DG4F
DY (HN63F2R61FRC4 (2FI))
