In [[Ken Iverson]]'s designs [[Rationalized APL]], [[A Dictionary of APL]], and the [[J]] language, the composition (<source lang=apl inline>⍤</source>) or Compose (<source lang=j inline>&</source>) refers to a different kind of composition, the [[Over]] operator. | In [[Ken Iverson]]'s designs [[Rationalized APL]], [[A Dictionary of APL]], and the [[J]] language, the composition (<source lang=apl inline>⍤</source>) or Compose (<source lang=j inline>&</source>) refers to a different kind of composition, the [[Over]] operator. | ||
More recently, the term "composition" is used in [[Dyalog APL]] to refer to any of a family of operators including [[Beside]] and [[Bind]] (<source lang=apl inline>∘</source>), [[Commute]] and [[Constant]] (<source lang=apl inline>⍨</source>), [[Atop]] (<source lang=apl inline>⍤</source>), and [[Over]] (<source lang=apl inline>⍥</source>).<ref>[[Marshall Lochbaum]].
