Subject: accessing hash values

Hi all, this is my first post to the Ruby Forum. Cheers. And thanks for
helping out a newb.

Quesiton: How do you access multiple values from a hash?

For Example, I have a hash of computer names, and their associated user.

  the_system = {
    "computer-01"=>"jill",
    "computer-02"=>"jack",
    "computer-03"=>"bob"
  }


If I want to access the user of one machine, this works great:

  puts the_system["computer-01"]
  =>jill


But how do I return multiple user names? (The below throws an error:
'wrong number of arguments'.)

  puts the_system["computer-01", "computer-02"]


Thanks.
