Hello World Program
A "Hello world" program is a computer program that outputs "Hello, world" on a display device. Because it is typically one of the simplest programs possible in most programming languages, it is by tradition often used to illustrate to beginners the most basic syntax of a programming language, or to verify that a language or system is operating correctly.
In a device that does not display text, a simple program to produce a signal, such as turning on an LED, is often substituted for "Hello world" as the introductory program.

Famous quotes containing the words world and/or program:
“The essence of the physicality of the most famous blonde in the world is a wholesome eroticism blurred a little round the edges by the fact she is not quite sure what eroticism is. This gives her her tentative luminosity and what makes her, somehow, always more like her own image in the mirror than she is like herself.”
—Angela Carter (1940–1992)
“The story is told of a man who, seeing one of the thoroughbred stables for the first time, suddenly removed his hat and said in awed tones, “My Lord! The cathedral of the horse.””
—For the State of Kentucky, U.S. public relief program (1935-1943)
