Addition of active and domain settings to the Variables specification.  In conjunction with the  changes to the Methods section of the Reference manual, this should complete the discussion  of the active variables.  NOTE:  I put the discussion of the active and domain keywords  after the variables set identifier but before all of the variable types.  If it should be at the  end of this section instead, we can easily change it.  I did not yet renumber the tables, but will  if the placement of this discussion is correct.
