That works fine, the output was "YAML". From what you said, that's a good sign. Now I'm still getting the same error message that I posted above when I run the program. "Macintosh: ~Xepha$ ruby /users/Xepha/Documents/for-v/numbered_news.rb /users/Xepha/Documents/for-v/numbered_news.rb:14: uninitialized constant YAML (NameError)" And, turns our 1.9.0 is the current one installed and running; she didn't know that it was preinstalled on macs. =/ So, yes she is running 1.9.0 now; YAML is "working" just not in the program that I've written. -- Posted via http://www.ruby-forum.com/.
