Hope I’m right and have given you some help! I’m new to ruby as well  
(about a week!). ( :

Err, that’s what one does to run an entire Ruby program from the command  
line, but you can use “load” and “require” from within irb just as you  
can from within a saved Ruby program.

I’m not sure what you mean by “Scrite”. I’m going to guess it’s a typo,  
and offer this correction:

Try SciTE. It’s an excellent programming-oriented GUI text editor.  
When I have to edit textfiles with a GUI application for some reason  
(such as the rare occasion of having to use Windows), SciTE is my  
favorite tool for the job. The rest of the time, I use Vim, of course.
