'''BS2000''' is an [[operating system]] for IBM 390-compatible [[mainframe computer]]s developed in the 1970s by [[Siemens]] (Data Processing Department EDV) and from early 2000s onward by [[Fujitsu Technology Solutions]].<ref>[https://globalsp.ts.fujitsu.com/dmsp/docs/ps_bs2000-strategy.pdf BS2000/OSD Strategy, March 2010]{{Dead link|date=October 2018 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><ref name=":0">{{cite web | url=https://en.wikibooks.org/wiki/360_Assembly | title=360 Assembly - Wikibooks, open books for an open world }}</ref>

Unlike other mainframe systems, BS2000 provides exactly the same user and programming interface in all operating modes (batch, interactive and online transaction processing) and regardless of whether it is running natively or as a guest system in a [[virtual machine]]. This uniformity of the user interface and the entire BS2000 software configuration makes administration and automation particularly easy.

Currently, it is mainly used in Germany - making up to 83% of its total user base - as well as in the United Kingdom (8%), Belgium (4.8%) and other European countries (Austria, Czech Republic, Denmark, Italy, Luxembourg, Netherland, Spain, Switzerland) (4.2%). 63% of all SE/S Servers are installed at the [[German tourism industry|German Travel Association (DRV)]] and [[Federal Central Tax Office|German Tax Authority]].<ref>{{cite web|url=https://sp.ts.fujitsu.com/dmsp/Publications/public/01-Kammermeier-Strategie.pdf|title=BS2000 – Geschäft und Strategie|date=10 November 2017|language=de|archive-url=https://web.archive.org/web/20200204054258/https://sp.ts.fujitsu.com/dmsp/Publications/public/01-Kammermeier-Strategie.pdf| archive-date=2020-02-04| url-status=dead}}</ref>
