RunRev is also known as Runtime Revolution or simply, Revolution. Many programmers say that a single language is never enough because there is no perfect language. According to the Tiobe index, RunRev is among the first 150 languages (and there are thousands of other languages) used in business and industry. RunRev is assigned to the same group as R, Mathematica, SPSS, AppleScript, PostScript, Oberon, VBScript and XSLT. Some software used in connection with Landsat 7 satellite is written in RunRev. Revolution was also being used in European Community 6th framework projects.
