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:
“With malice toward none, with charity for all, with firmness in the right, as God gives us to see the right, let us strive on to finish the work we are in, to bind up the nation’s wounds, to care for him who shall have borne the battle, and for his widow and his orphan, to do all which may achieve and cherish a just and lasting peace among ourselves, and with all nations.”
—Abraham Lincoln (1809–1865)
“We’d like to fight but we fear defeat,
We’d like to work but we’re feeling too weak,
We’d like to be sick but we’d get the sack,
We’d like to behave, we’d like to believe,
We’d like to love, but we’ve lost the knack.”
—Cecil Day Lewis (1904–1972)
“It is the privilege of any human work which is well done to invest the doer with a certain haughtiness. He can well afford not to conciliate, whose faithful work will answer for him.”
—Ralph Waldo Emerson (1803–1882)
