WSFN (Which Stands for Nothing) is an interpreted programming language for controlling robots created by Li-Chen Wang. It was designed to be as small as possible, a "tiny" language, similar to Wang's earlier effort, Palo Alto Tiny BASIC.

A programming language is any set of rules that converts strings, or graphical program elements in the case of visual programming languages, to various kinds of machine code output. Programming languages are one kind of computer language, and are used in computer programming to implement algorithms.

<language> A formal language in which computer programs are written. The definition of a particular language consists of both syntax (how the various symbols of the language may be combined) and semantics (the meaning of the language constructs). Languages are classified as low level if they are close to machine code and high level if each language statement corresponds to many machine code instructions (though this could also apply to a low level language with extensive use of macros, in which case it would be debatable whether it still counted as low level). A roughly parallel classification is the description as first generation language through to fifth generation language. The other major classification of languages distinguishes between imperative languages, procedural language and declarative languages. {Programming languages time-line/family tree (http://levenez.com/lang/history.html)}.
