**@xs** stores urls like www.yahoo.com, www.google.com

```
for x in @xs
     y = x... #do something with x
     @result += y  #i want to do something like that. i want to store them in @result. What do i have to write in here?
end

```

Sorry for noob question. By the way how do you call @result ? Is it an instance variable or an array ?
