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:
“Erasmus was the light of his century; others were its strength: he lighted the way; others knew how to walk on it while he himself remained in the shadow as the source of light always does. But he who points the way into a new era is no less worthy of veneration than he who is the first to enter it; those who work invisibly have also accomplished a feat.”
—Stefan Zweig (18811942)
“Until women learn to want economic independence ... and until they work out a way to get this independence without denying themselves the joys of love and motherhood, it seems to me feminism has no roots.”
—Crystal Eastman (1881–1928)
“Parenting can be established as a time-share job, but mothers are less good “switching off” their parent identity and turning to something else. Many women envy the father’s ability to set clear boundaries between home and work, between being an on-duty and an off-duty parent.... Women work very hard to maintain a closeness to their child. Father’s value intimacy with a child, but often do not know how to work to maintain it.”
—Terri Apter (20th century)
