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:
“Rejecting all organs of information ... but my senses, I rid myself of the Pyrrhonisms with which an indulgence in speculations hyperphysical and antiphysical so uselessly occupy and disquiet the mind.”
—Thomas Jefferson (1743–1826)
“Just as language has no longer anything in common with the thing it names, so the movements of most of the people who live in cities have lost their connexion with the earth; they hang, as it were, in the air, hover in all directions, and find no place where they can settle.”
—Rainer Maria Rilke (1875–1926)
