In 1965, Ken Iverson's group in Yorktown was wrestling with the transition from Iverson Notation, a notation suited for blackboards and printed pages, to a machine-executable programming environment. Iverson had already developed a Selectric typeball and was writing a high-school math textbook. By autumn 1965, Larry Breed and Stanford grad student Philip Abrams had written the first implementation in 7090 Fortran (with batch execution). Eugene McDonnell was looking for applications to run on TSM, his project's experimental time-sharing system on a virtual-memory 7090. With his help, Breed ported the Fortran code, added I\/O routines for the 1050 terminals, called the result IVSYS; and Iverson Notation went interactive.<\/jats:p>","DOI":"10.1145\/1088529.1088533","type":"journal-article","created":{"date-parts":[[2007,1,17]],"date-time":"2007-01-17T18:32:02Z","timestamp":1169058722000},"page":"26-27","update-policy":"http:\/\/dx.doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["How we got to APL\/1130"],"prefix":"10.1145","volume":"34","author":[{"given":"Larry","family":"Breed","sequence":"first","affiliation":[]}],"member":"320","published-online":{"date-parts":[[2004,3]]},"container-title":["ACM SIGAPL APL Quote Quad"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/dl.acm.org\/doi\/pdf\/10.1145\/1088529.1088533","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2022,12,28]],"date-time":"2022-12-28T16:02:56Z","timestamp":1672243376000},"score":1,"resource":{"primary":{"URL":"https:\/\/dl.acm.org\/doi\/10.1145\/1088529.1088533"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,3]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2004,3]]}},"alternative-id":["10.1145\/1088529.1088533"],"URL":"https:\/\/doi.org\/10.1145\/1088529.1088533","relation":{},"ISSN":["0163-6006"],"issn-type":[{"value":"0163-6006","type":"print"}],"subject":[],"published":{"date-parts":[[2004,3]]},"assertion":[{"value":"2004-03-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
