Bryon,

I have something in java...

public void addLine(double[] arg){

        lineObj line = new lineObj();

        for(int i=2;i<arg.length;i=i+2){

            pointObj p = new pointObj(arg[i],arg[i+1],0);
            line.add(p);

        }

        layerObj layer = map.getLayerByName("COSMETIC");
        shapeObj shape = new shapeObj(mapscript.MS_SHAPE_LINE);
        shape.add (line);

        layer.addFeature(shape);

    }

WHERE COSMETIC IS:

LAYER
 NAME COSMETIC
 TYPE LINE
 STATUS DEFAULT
 CLASS
  STYLE
   SIZE 5
   SYMBOL 'street'
  END
  COLOR 255 0 0
  OUTLINECOLOR 171 158 137
 END
END

I use this to add a line to the map, temporarily.
