Subject: Re: New to Ruby - Scope Question

Thanks for getting back to me as well Jan. Was using Sublime Text 2 and 
doing builds in that after entering code, but recently switched over to 
trying to do more via IRB, which I feel is giving me a deeper 
understanding, but I seem to be making more mistakes in. Going to step 
up my meticulousness!
