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 work together
A Church for all
And a job for each
Every man to his work.”
—T.S. (Thomas Stearns)
“The poet needs a ground in popular tradition on which he may work, and which, again, may restrain his art within the due temperance. It holds him to the people, supplies a foundation for his edifice; and, in furnishing so much work done to his hand, leaves him at leisure, and in full strength for the audacities of his imagination.”
—Ralph Waldo Emerson (1803–1882)
“You do not become a “dissident” just because you decide one day to take up this most unusual career. You are thrown into it by your personal sense of responsibility, combined with a complex set of external circumstances. You are cast out of the existing structures and placed in a position of conflict with them. It begins as an attempt to do your work well, and ends with being branded an enemy of society.”
—Václav Havel (b. 1936)
