Acting Directly on Passed Parameters

• Here is an exmaple of how you can directly modify the parameters passed to a function:

  sub increment_all {
     for (@_) {
        ++$_;
     }
  }
  
  my @nums = qw(3 8 -2 41);
  print "Orig numbers = @nums\n";
  increment_all(@nums);
  print "New numbers  = @nums\n";
