Editing APL (programming language) (section)

=== APL\360 ===
The first implementation of APL using recognizable APL symbols was APL\360 which ran on the [[IBM System/360]], and was completed in November 1966<ref name="Birthdate">{{cite web |url=http://www.jsoftware.com/papers/APLQA.htm#APL_birthday |title=APL Quotations and Anecdotes |website=jsoftware.com |access-date=April 14, 2018}}</ref> though at that time remained in use only within IBM.<ref name="FalkoffIBMFamily"/> In 1973 its implementors, [[Lawrence M. Breed|Larry Breed]], [[Richard H. Lathwell|Dick Lathwell]] and [[Roger Moore (computer scientist)|Roger Moore]], were awarded the [[Grace Murray Hopper Award]] from the [[Association for Computing Machinery]] (ACM). It was given "for their work in the design and implementation of APL\360, setting new standards in simplicity, efficiency, reliability and response time for interactive systems."<ref>{{cite web |title=Awards – 1973 – Lawrence Breed |publisher=Association for Computing Machinery |url=http://awards.acm.org/citation.cfm?id=0694605&srt=all&aw=145&ao=GMHOPPER&yr=1973 |url-status=dead |archive-url=https://web.archive.org/web/20120402212031/http://awards.acm.org/citation.cfm?id=0694605&srt=all&aw=145&ao=GMHOPPER&yr=1973 |archive-date=April 2, 2012}}</ref><ref>{{cite web |title=Awards – 1973 – Richard Lathwell|publisher=Association for Computing Machinery |url=http://awards.acm.org/citation.cfm?id=3412588&srt=all&aw=145&ao=GMHOPPER&yr=1973 |url-status=dead |archive-url=https://web.archive.org/web/20120402212035/http://awards.acm.org/citation.cfm?id=3412588&srt=all&aw=145&ao=GMHOPPER&yr=1973 |archive-date=April 2, 2012}}</ref><ref>{{cite web |title=Awards – 1973 – Roger Moore|publisher=Association for Computing Machinery |url=http://awards.acm.org/citation.cfm?id=4987585&srt=all&aw=145&ao=GMHOPPER&yr=1973 |url-status=dead |archive-url=https://web.archive.org/web/20120402212037/http://awards.acm.org/citation.cfm?id=4987585&srt=all&aw=145&ao=GMHOPPER&yr=1973 |archive-date=April 2, 2012}}</ref>

In 1975, the [[IBM 5100]] microcomputer offered APL\360<ref>{{cite web|url=http://www.old-computers.com/museum/computer.asp?c=795 |title=IBM 5100 |website=old-computers.com|access-date=April 8, 2018 |archive-url=https://web.archive.org/web/20180430050157/http://www.old-computers.com/museum/computer.asp?c=795|archive-date=April 30, 2018|url-status=dead}}</ref> as one of two built-in ROM-based interpreted languages for the computer, complete with a keyboard and display that supported all the special symbols used in the language.<ref name="byte197512">{{cite magazine| url=https://archive.org/stream/byte-magazine-1975-12/1975_12_BYTE_00-04_Assembling_an_Altair#page/n91/mode/2up |title=Welcome, IBM, to personal computing |magazine=[[Byte (magazine)|Byte]] |date=December 1975 |access-date=April 29, 2018 |pages=90}}</ref>

Significant developments to APL\360 included CMS/APL, which made use of the [[Virtual memory|virtual storage]] capabilities of [[Conversational Monitor System|CMS]] and APLSV, which introduced [[shared variable]]s, system variables and system functions. It was subsequently ported to the [[IBM System/370]] and [[Virtual Storage Personal Computing|VSPC]] platforms until its final release in 1983, after which it was replaced by APL2.<ref name="FalkoffIBMFamily"/>
