In 1965, Ken Iverson's group in Yorktown was wrestling with the transition from Iverson Notation, a notation suited for blackboards and printed pages, to a machine-executable programming environment. Iverson had already developed a Selectric typeball(More)

What became to be known as Iverson notation is the first recognizable APL-like notation. "A Formal Description of System~360" by Falkoff, Iverson, and S u s s e n g u t h in the(More)
We present a generalization of the extension of scalar dyadic functions with one-element operands. The generalization retains the spirit of APL scalar extension, brings into harmony the present rules for extension of one-element arrays, and provides useful new APL constructions. Some contrasts with Dr. S. Charmonman's proposed generalization, and some(More)
