You can run any Ruby script from a command window if you know how to use that (ruby yourgame.rb). Or you can use an editor such as SciTE that display error messages within its own window, which is much more productive. It is not the best editor but it is free: http://www.scintilla.org/SciTE.html HTH, Julian
