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:
“There is no mystery in a looking glass until someone looks into it. Then, though it remains the same glass, it presents a different face to each man who holds it in front of him. The same is true of a work of art. It has no proper existence as art until someone is reflected in it—and no two will ever be reflected in the same way. However much we all see in common in such a work, at the center we behold a fragment of our own soul, and the greater the art the greater the fragment.”
—Harold C. Goddard (1878–1950)
“How did you get in the Navy? How did you get on our side? Ah, you ignorant, arrogant, ambitious—keeping sixty two men in prison cause you got a palm tree for the work they did. I don’t know which I hate worse, you or that malignant growth that stands outside your door. How did you ever get command of a ship? I realize in wartime they have to scrape the bottom of the barrel. But where’d they ever scrape you up?”
—Frank S. Nugent (1908–1965)
“... to work, to work hard, to see work steadily, and see it whole, was the way to be reputable. I think I always respected a good blacksmith more than a lady of leisure.”
—Elizabeth Stuart Phelps (1844–1911)
