Editing Turing (programming language) (section)

==Overview==
Named after British computer scientist [[Alan Turing]], Turing is used mainly as a teaching language at the high school and university level.<ref>{{cite journal |last1=Fluck |first1=A. |last2=Webb |first2=M. |last3=Cox |first3=M. |last4=Angeli |first4=C. |last5=Malyn-Smith |first5=J. |last6=Voogt |first6=J. |last7=Zagami |first7=J. |date=2016 |title=Arguing for computer science in the school curriculum |journal=Journal of Educational Technology & Society |volume=19 |issue=3 |pages=38–46}}</ref> Two other versions exist, [[#Object-Oriented Turing|Object-Oriented Turing]] and [[#Turing+|Turing+]], a systems programming variant. In September 2001, "Object Oriented Turing" was renamed "Turing" and the original Turing was renamed "Classic Turing". Turing is now unsupported by Holt Software Associates in [[Toronto, Ontario]]. Turing was widely used in high schools in [[Ontario]] as an introduction to programming.<ref>{{Cite web|url=http://compsci.ca/holtsoft/|title=Download Turing & RTP (Ready to Program)|last=info@compsci.ca|website=compsci.ca|access-date=2018-08-21}}</ref>

On November 28, 2007, Turing, which was previously a commercial programming language, became freeware, available to download from the developer's website free of charge for personal, commercial, and educational use.<ref name=holtsoft>{{cite web |url=http://www.holtsoft.com |title=Holt Software Associates |date=January 2008 |access-date=2010-04-10 |url-status=dead |archive-url=https://web.archive.org/web/20100405101149/http://www.holtsoft.com/ |archive-date=2010-04-05}}</ref><ref name="holtsoft/old_index">{{cite web |url=http://www.holtsoft.com/old_index.html |title=Holt Software Associates (old) |date=2007-11-25 |access-date=2010-04-10 |url-status=dead |archive-url=https://web.archive.org/web/20100417185823/http://www.holtsoft.com/old_index.html |archive-date=2010-04-17}}</ref><ref>{{Cite web |url=http://compsci.ca/blog/download-turing-411/ |title=Download Turing 4.1.1 |access-date=2009-01-10 |publisher=compsci.ca Blog |date=2007-11-28}}</ref>

The makers of Turing, Holt Software Associates, have since ceased operations, and Turing has seen no further development since November 25, 2007.<ref name="holtsoft/old_index"/>
