Information Processing Language (IPL) is a programming language developed by Allen Newell, Cliff Shaw, and Herbert A. Simon at RAND Corporation and the Carnegie Institute of Technology from about 1956. Newell had the role of language specifier-application programmer, Shaw was the system programmer and Simon took the role of application programmer-user.
The language includes features intended to support programs that could perform general problem solving, including lists, associations, schemas (frames), dynamic memory allocation, data types, recursion, associative retrieval, functions as arguments, generators (streams), and cooperative multitasking. IPL pioneered the concept of list processing, albeit in an assembly-language style.

Famous quotes containing the words information and/or language:
“In the information age, you don’t teach philosophy as they did after feudalism. You perform it. If Aristotle were alive today he’d have a talk show.”
—Timothy Leary (b. 1920)
““What may this mean? Language of Man pronounced
By tongue of brute, and human sense expressed!
The first at least of these I thought denied
To beasts, whom God on their creation-day
Created mute to all articulate sound;
The latter I demur, for in their looks
Much reason, and in their actions, oft appears.”
—John Milton (1608–1674)
