In APL a [[user-defined operator]] such as a [[tradop]] or [[dop]] creates a derived function from its arguments without executing any of the user's code. In [[J]], the user's code is evaluated and must return a value, which could but doesn't have to be a derived function. | In APL a [[user-defined operator]] such as a [[tradop]] or [[dop]] creates a derived function from its arguments without executing any of the user's code.
