I am reading the Programming Ruby book by Dave T. (2nd edition)  
and he mentions a trick when you want to use irb to try example code  
and directs you how to load “code/rdoc/fib\_example.rb”. I just  
downloaded the latest version of Ruby and I can’t find any such file.  
I also can’t find a code folder or is “code” as used in that line a  
programming directive?

Not 100% sure, so I apologize in advance if I’m wrong. (It happens quite  
frequently, as a matter of fact.) In any case, the ‘code’ for the book  
is  
at:

[http://www.pragmaticprogrammer.com/titles/ruby/code/index.html](http://www.pragmaticprogrammer.com/titles/ruby/code/index.html)

## I’m not sure if they’re referring to that or not, but just in case, there it is. 🙂
