Ey guys. Look at this: a = "mom" if a == ( "dad" || "mom" ) puts "Hi" end Very simple. I saw a kind of this exercise in a book that I'm studing( yes...I'm noob in this ), and I gave it by understood, but now when I'm practicing i see that...this has not happen. That chunk of code return me nil...but, judging by the book, that should return me "Hi" right? Because I say: if a is equal to "dad" or "mom" say "Hi". I don't know if is my OS( Windows XP SP3( I've had several troubles with it )) or if is the last version of Ruby, which I am using, the 1.9.3 or what... I'll appreciate your time guys, thanks. -- Posted via http://www.ruby-forum.com/.
