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:
“Writing a book I have found to be like building a house. A man forms a plan, and collects materials. He thinks he has enough to raise a large and stately edifice; but after he has arranged, compacted and polished, his work turns out to be a very small performance. The authour however like the builder, knows how much labour his work has cost him; and therefore estimates it at a higher rate than other people think it deserves,”
—James Boswell (1740–1795)
“Don’t you know there are 200 temperance women in this county who control 200 votes. Why does a woman work for temperance? Because she’s tired of liftin’ that besotted mate of hers off the floor every Saturday night and puttin’ him on the sofa so he won’t catch cold. Tonight we’re for temperance. Help yourself to them cloves and chew them, chew them hard. We’re goin’ to that festival tonight smelling like a hot mince pie.”
—Laurence Stallings (1894–1968)
“Well said, old mole, canst work i’ th’ earth so fast?”
—William Shakespeare (1564–1616)
