I haven't read it, but heard good things. Google pointed to this web site: http://pine.fm/LearnToProgram The info on the site is a bit dated (Ruby 1.8.x is ancient), in particular the latest Ruby installer does not include SciTE If you have a favourite text editor, use it to edit the .rb files (Ian has indicated the way). You can get a SciTE windows installer at http://opensource.ebswift.com/SciTEInstaller/ As for the command prompt, if the text file is an empty file then that is probably why it gave the error. In any case, providing copy of the commands you are using, and the results you get will make it easier for others to provide help Cheers Chris
