From: Chuck Brotman Date: 2010-06-22T08:15:04+09:00 Subject: Re: General Confusion Robert, Thanks again for your (second) response. I will probably print it out and study it. I appreciate you taking your time to explain and provide examples And yes, it occurred to me (last night) that I should work to hide the implementation... but first I want to have an implementation to hide ;) Also a big thank you to Gary Wright Whose reply reached me by email, but I haven't seen in the forum. He also gave me a lengthy reply, replete with sound advice and examples! Thanks, I'll be reviewing both responses until I get a handle on this Best regards, Chuck -- Posted via http://www.ruby-forum.com/.
