Work
Iverson developed a mathematical notation that became known as Iverson Notation for manipulating arrays that he taught to his students, and described in his 1962 book A Programming Language. In 1960, he began work for IBM and working with Adin Falkoff, created APL based on the notation he had developed. He was named an IBM Fellow in 1970.
In late 1989, Ken Iverson and Roger Hui began collaboration on an advanced continuation of an APL-like language which they called J, first demonstrated publicly at the APL90 conference the next year. The improvements were intended to fix some of the persistent character set issues that plagued APL since its inception, and to add new advanced features such as functional programming, arrays of variables, and support for parallel MIMD operations, some of which do not appear in APL today. It was intended that the J language be an improvement over existing APL. The J interpreter and language continues to evolve today. A version is available from J Software under the GPL3 license.

Famous quotes containing the word work:
“They that goe downe to ‘th sea in ships:
Their busines there to doo
In waters great. The Lords work see,
I’th deep his wonders too.”

“It is necessary to get a lot of men together, for the show of the thing,—otherwise the world will not believe. That is the meaning of committees. But the real work must always be done by one or two men.”
—Anthony Trollope (1815–1882)
“It is not enough for us to prostrate ourselves under the tree which is Creation, and to contemplate its tremendous branches filled with stars. We have a duty to perform, to work upon the human soul, to defend the mystery against the miracle, to worship the incomprehensible while rejecting the absurd; to accept, in the inexplicable, only what is necessary; to dispel the superstitions that surround religion—to rid God of His Maggots.”
—Victor Hugo (1802–1885)
