Editing PILOT (section)

==Derivatives==
Extensions to core PILOT include [[Array data structure|arrays]] and [[floating point]] numbers in Apple PILOT for the [[Apple II]], and [[Logo programming language|LOGO]]-inspired [[turtle graphics]] in Atari PILOT for [[Atari 8-bit computers]].<ref>{{Cite book |title= Atari PILOT for beginners |author=Jim Conlan, Tracy Deliman |publisher= Reston Publishing |year= 1983 |isbn=9780835903028 |url= https://books.google.com/books?id=VujzAAAAMAAJ }}</ref>

Between 1979 and 1983 the UK PILOT User Group was run by Alec Wood a teacher at Wirral Grammar School for Boys, Merseyside UK.  Several machine code versions of a mini PILOT were produced for the microcomputers of the time and a school in Scotland developed an interactive foreign language tutorial where pupils guided footprints around a town asking and answering questions in German, French, etc. An article in the December 1979 of ''Computer Age'' covered an early implementation called Tiny Pilot and gave a complete machine code listing.

Versions of PILOT written using [[BASIC]] interpreters were released in the 1970s and early 1980s. The April 1973 edition of [[People's Computer Company]]'s newsletter included such a system written in [[HP Time-Shared BASIC]] for the [[HP 2100]] system.<ref>{{cite magazine |magazine=People's Computer Company |date=April 1973 |title=PILOT '73 |pages=11-17 |url=https://archive.org/details/1973-04-peoples-computer-company/page/11}}</ref>  PETPILOT (PILOT for the Commodore PET) was the first non-Commodore language for the PET and was written in Microsoft BASIC which shipped with the PET, with a little assistance from Bill Gates.  It was created in 1979 by Dave Gomberg and could run on a 4K PET (which was never shipped) and ran well on the 8K PETs that Commodore shipped.  It was written in Larry Tessler's living room on PET serial number 2. In 1978, [[Byte Magazine]] published a non-[[Turing complete]] derivative of PILOT known as Waduzitdo by Larry Kheriarty.<ref>{{Cite web |title= Waduzitdo 2001 |author= Brian Connors |date= April 6, 2001 |url= http://www.reocities.com/ResearchTriangle/Station/2266/tarpit/waduzitdo/wdzref.html |access-date= October 13, 2011 }}</ref><ref>{{Cite news |title= WADUZITDO: How To Write a Language in 256 Words or Less |work= Byte |author= Larry Kheriarty |date= September 1978 }}</ref>

Atari PILOT, released in [[ROM cartridge]] form in 1981 for the Atari 8-bit computers, added [[turtle graphics]] and sound support.<ref>{{cite web |url=https://www.atarimania.com/pgesoft.awp?version=15785 |title=Atari PILOT |website=Atari Mania}}</ref> These instructions used two-letter commands. Atari used PILOT as one of their primary languages at the [[computer camp]]s they ran in the early 1980s.<ref>{{cite web |url=https://www.atarimania.com/documents/atari-computer-camps.pdf |title=Atari Computer Camps }}</ref>

1983's Vanilla PILOT for the [[Commodore 64]] also added turtle graphics,<ref name="info">{{Cite news |title= Vanilla PILOT, PILOT that comes with turtle graphics |work= Infoworld |date= September 12, 1983 |pages= 67–69 |url= https://books.google.com/books?id=ry8EAAAAMBAJ&pg=PA67 |access-date= October 13, 2011 }}</ref> as did ''Super Turtle PILOT'' which was published as a type-in listing in the October 1987 issue of [[COMPUTE!]] magazine.<ref>[http://www.atarimagazines.com/compute/issue89/Super_Turtle_Pilot.php Atarimagazines.com - COMPUTE!

In 1991 the [[Institute of Electrical and Electronics Engineers]] (IEEE) published a standard for Pilot as IEEE Std 1154-1991. It has since been withdrawn.<ref>{{Cite book |title= IEEE Standard 1154-1991 for Programmed Inquiry, Learning, or Teaching (PILOT) |year= 1991 |publisher= IEEE Standards Committee  |url= http://standards.ieee.org/reading/ieee/std_public/description/busarch/1154-1991_desc.html |archive-url= https://web.archive.org/web/20000311113026/http://www.standards.ieee.org/reading/ieee/std_public/description/busarch/1154-1991_desc.html |url-status= dead |archive-date= March 11, 2000 |doi= 10.1109/IEEESTD.1991.108548 |isbn= 0-7381-1184-8 }}</ref> A [[reference implementation]] based on this was implemented by [[Eric Raymond]], and maintained—-reluctantly—-for the next 15 years.<ref>{{cite web |title= Twenty years after |url= http://esr.ibiblio.org/?p=7244 }}</ref>

In 1990 eSTeem PILOT for Atari ST computers was developed and programmed by Tom Nielsen, EdD. Based on the IEEE Standards for PILOT, it includes Atari-specific features such as control of Laserdisc and CDROM devices.<ref>{{Cite news |title= Press Release: eSTeem PILOT |url=http://www.atariarchives.org/cfn/06/08/03/0046.php }}</ref>

A 2018 hobbyist implementation, psPILOT, based in part on the IEEE standard, was implemented using Microsoft's PowerShell scripting language.<ref>{{cite web |title= psPilot |url=https://github.com/FreeTrav/psPILOT }}</ref>
