In the DATA statement, list the names for each of the new data sets you want to create, separated by spaces. Then in the body of the data step, you'll write an OUTPUT statement for each dataset name you've specified.
As the archetypal superhero, Superman is nearly invulnerable except for his weakness to Kryptonite. An alien from the planet Krypton, Superman derives his powers from his presence on Earth.
Superman (and, Kryptonians) has superpowers on Earth because of our yellow Sun (Krypton's Sun was red). Kryptonite blocks that ability. Also, its radiation is poisonous to Kryptonians which can kill them (although, I have read comics in which Superman had developed some immunity against green Kryptonite).
