Famous quotes containing the words program and/or output:
“The rumor of a great city goes out beyond its borders, to all the latitudes of the known earth. The city becomes an emblem in remote minds; apart from the tangible export of goods and men, it exerts its cultural instrumentality in a thousand phases.”

And gave her mother forty whacks;
When she saw what she had done,
