Correct. Basically, I do this when adding to the list:

$stepList.append(Step.new(firstStep, thisStep, thisFilter))

Here 'firstStep', 'thisStep' and 'thisFilter' are just text values that are 
read in from an XML file. (Incidentally, most of this is copied largely from 
the Pickaxe book. I hijacked the examples of Song and SongList since they 
seemed fairly close to what I needed to do.)

The 'to_s' method I have in the Step class looks like this:

<code>
class Step
...
  def to_s
    if (@filter != nil && @filter != "")
      "#@point1, #@point2, #@filter"
    else
      "#@point1, #@point2"
    end
  end
end
</code>

So it's nothing really fancy.

Beyond this, I will try the suggestions you bring up here.
