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:
“Your children get a lot of good stuff out of your work...They benefit from the tales you tell over dinner. They learn from the things you explain to them about what you do. They brag about you at school. They learn that work is interesting, that it has dignity, that it is necessary and pleasing, and that it is a perfectly natural thing for both mothers and fathers to do...Your work enriches your children more than it deprives them.”
—Louise Lague (20th century)
“Poetry is the only life got, the only work done, the only pure product and free labor of man, performed only when he has put all the world under his feet, and conquered the last of his foes.”
—Henry David Thoreau (1817–1862)
“We are weighed down, every moment, by the conception and the sensation of Time. And there are but two means of escaping and forgetting this nightmare: pleasure and work. Pleasure consumes us. Work strengthens us. Let us choose.”
—Charles Baudelaire (1821–1867)
