Editing STOS BASIC (section)

==History==
Although the first version of ''STOS'' to be released in the [[United Kingdom|UK]] (version 2.3) was released in late 1988 by [[Mandarin Software]], a version had been released earlier in [[France]].

Version 2.3 was bundled with three complete games (''Orbit'', ''Zoltar'' and ''Bullet Train''), and many accessories and utilities (such as [[Sprite (computer graphics)|sprite]] and music editors). Initially implemented as a [[BASIC interpreter]], a [[compiler]] was soon released that enabled the user to compile the ''STOS Basic'' program into an executable file that ran a lot faster because it was [[compiler|compiled]] rather than [[interpreter (computer software)|interpreted]]. In order to be compatible with the compiler, STOS needed to be upgraded to version 2.4 (which came with the compiler). STOS 2.4 also fixed a few bugs and had faster [[floating point]] mathematics code, but the floating point numbers had a smaller range.

STOS 2.5 was released to make STOS run on Atari STEs with [[Atari TOS|TOS]] 1.06 (1.6), and then STOS 2.6 was needed to make STOS run on Atari STEs with TOS 1.62. STOS 2.7 was a compiler-only upgrade that made programs with the STOS [[music tracker|tracker]] extension (used to play [[Module file|MOD]] music) compile.

There was a 3rd-party hack called STOS 2.07 designed to make ''STOS'' run on even more TOS versions, and behave on the [[Atari Falcon]].

Around 2001 [[François Lionet]] released via the [[Clickteam]] website the [[source code]] of STOS BASIC.<ref>[https://web.archive.org/web/20071130053321/http://clickteam.com/eng/downloadcenter.php?i=58 Amos & Stos » Main Download] on clickteam.com (archived 2007)</ref>

On the 4th of April, 2019 [[François Lionet]] announced the release of AMOS2 on his website [http://amos2.tech/ Amos2.tech] {{Webarchive|url=https://web.archive.org/web/20200923044846/http://amos2.tech/ |date=2020-09-23 }}. AMOS2 replaces STOS and AMOS together, using [[JavaScript]] as its code interpreter, making the new development system independent and generally deployed in web browsers.

AMOS2 is now known as AOZ Studio.<ref>{{Cite web|url=https://www.aoz.studio/|title=AOZ Studio to create your apps and games|website=AOZ Studio|language=en|access-date=2020-03-12}}</ref>
