  Hi James, 

  You can do: 

  sub param_test ($$$) { 
     my ( $tom, $george, $array_ref ) = @_; 

  } 

  That will ensure that three scalars are passed in.  However, using
  subroutine parameter checking like this isn't considered a best
  practice. 

  Check out the Prototypes section of 'man perlsub' if you want
  more info on it.
