The '''Polymorphic Programming Language''' ('''PPL''') was developed in 1969 at [[Harvard University]] by Thomas A. Standish. It is an [[interactive computing|interactive]], [[extensible programming|extensible]] language with a [[base language]] similar to the language [[APL (programming language)|APL]].<ref>{{cite journal |last=Standish |first=Thomas A. |date=August 1969 |editor1-last=Christensen |editor2-last=Shaw |title=Some features of PPL – a Polymorphic Programming Language |url=http://portal.acm.org/citation.cfm?id=1115858.1115864&coll=GUIDE&dl=GUIDE |volume=4 |issue=8 |pages=20–26 |doi=10.1145/1115858.1115864 |access-date=2018-06-23 |journal=ACM SIGPLAN Notices |language=en |edition=Proceedings of Extensible Language Symposium |location=ACM Digital Library |publisher=[[Association for Computing Machinery]]|url-access=subscription }}</ref><br />
