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:
“Who wants a world in which the guarantee that we shall not die of starvation entails the risk of dying of boredom?”
—Raoul Vaneigem (b. 1934)
“The present century has not dealt kindly with the farmer. His legends are all but obsolete, and his beliefs have been pared away by the professors at colleges of agriculture. Even the farm- bred bards who twang guitars before radio microphones prefer “I’m Headin’ for the Last Roundup” to “Turkey in the Straw” or “Father Put the Cows Away.””
—For the State of Kansas, U.S. public relief program (1935-1943)
