This paper proposes two related extensions to APL: the extension of assignment to allow a name F to be assigned to a derived function by an expression of the form F←+.x, and the introduction of a dyadic operator @@@@ to apply to character arrays D and M so that D@@@@M produces an ambivalent function in which the dyadic case is defined by D and the monadic case by M.
