I’ve just found ruby and want to teach it to my son & myself, and have found several tutorials that will work fine, I’ve loaded ruby on my pc (the newest version) I’ve written a small sample program prog.rb - when i try to run it from the command prompt it doesnt recognize the command… It’s been a dozen years since I’ve programmed anythig, and was never good, but think it may have something to do with my default paths? Please help me just get ruby running properly - i tried looking through the posts, but didnt find anything in my searching, but i’m sure it because I didnt know where to look. Many many thanks. -Ron ---

Next, if you use the One Click Installer, run its Scite program. That lets you just hit each time you change the code.
