Dear Sir,

I am a unversity student doing a project on mapserver. I have some problems in 
adding labels/symbols on the map. I want to add a label on some specific 
positions on the map but not all the features on a layer.

For example,
# 4 layer RAIL
  layer
type line
    classitem "FNODE_"
    data "RAIL_arc_arc"
    footer "RAIL_arc_arc_footer.html"
    group "RAIL"
    header "RAIL_arc_arc_header.html"
    labelcache on
    labelitem "FNODE_"
    name "RAIL"
    postlabelcache true
    status on

    #  class RAIL_1
    class
      template "RAIL_arc_arc_query.html"
      backgroundcolor 128 128 128
      color 128 128 128
      name "RAIL_1"
      outlinecolor 0 0 0
SYMBOL 'interstate_shield'
    end
  end

The above code in mapfile will display all the features in the RAIL layer. 
However, I only want to display symbol on a specific coordinate and all the 
other things left normal.

I have spent a lot of time on it but not succeed.
Can you give me some examples of how to do this?
I will be very grateful if you can help.

Thank you very much.

Joyce
