It looks like others have already clarified things for you. This is a
bit of a tangent, but I just wanted to mention that 'map' is
superfluous in the above code i.e. the output is identical with and
without it.

irb(main):001:0> r = ['KLP','OGN' ]
=> ["KLP", "OGN"]
irb(main):002:0> r
=> ["KLP", "OGN"]
irb(main):003:0> r.map
=> ["KLP", "OGN"]
