To James, I'm still on windows xp.

I tried putting the calc.rb file inside the bin folder, and "ruby 
calc.rb" worked, as well as "calc" and "calc.rb"

Is this what you guys were saying?

The tutorial didn't say anything about the bin folder or where exactly 
to save the programs.  It only said to make a folder wherein my programs 
could be saved, and that's what I did.  But then it instructed to type 
"ruby calc.rb" and I got confused.

I still don't understand the logic behind it.
Do I have to bother with this?
Do I always have to save my programs in the bin folder?

Please excuse the ignorance. I'm a novice.
