'''Information Processing Language''' (IPL) was a [[programming language]] developed by [[Allen Newell]], [[Cliff Shaw]] and [[Herbert Simon]] at [[RAND Corporation]] and the [[Carnegie Institute of Technology]] from about [[1956]]. It included 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, and generators (streams), and [[cooperative multitasking]]. Newell had the role of language specifier/application programmer, Shaw was the system programmer and Simon took the role of application programmer/user.

IPL was used to implement two of the first [[artificial intelligence]] programs, by the same authors: the [[Logic Theory Machine]] (1956) and the [[General Problem Solver]] (1957), and also their [[chess]] program [[NSS]] (1958).
