Editing J (programming language) (section)

==Documentation==
J's documentation includes a [http://code.jsoftware.com/wiki/NuVoc dictionary], with words in J identified as [http://code.jsoftware.com/wiki/Vocabulary/Nouns nouns], [http://code.jsoftware.com/wiki/Vocabulary/Verbs verbs], [http://code.jsoftware.com/wiki/Vocabulary/Modifiers modifiers], and so on. Primary words are listed in the [http://code.jsoftware.com/wiki/Vocabulary/Words vocabulary], in which their respective [http://code.jsoftware.com/wiki/Vocabulary/PartsOfSpeech parts of speech] are indicated using markup. Note that verbs have two forms: [[Arity|monadic]] (arguments only on the right) and [[Arity|dyadic]] (arguments on the left and on the right). For example, in '<code>-1</code>' the hyphen is a monadic verb, and in '<code>3-2</code>' the hyphen is a dyadic verb. The monadic definition is mostly independent of the dyadic definition, regardless of whether the verb is a primitive verb or a derived verb.
