Hello Bob !

Hiliting a feature on map would require you to add another layer for
hiliting.
For example, the way i do hilite as follows:

First, define the hiliting style:

  SYMBOL
    NAME 'circle'
    TYPE ELLIPSE
    FILLED TRUE
    POINTS 1 1 END
  END

Secondly, add a layer for hiliting:

  LAYER
    NAME 'districts_selection'
    DATA './districts'
    TYPE polygon
    STATUS off
    MINSCALE 9500
    METADATA
      "tile_source" "nocache"
    END
    CLASSITEM "OBJECTID"
    CLASS
      EXPRESSION ([OBJECTID] in '%districts_ids%')
      STYLE
        COLOR -1 -1 -1
        OUTLINECOLOR 115 223 255
        SYMBOL 'circle'
        SIZE 5
      END
    END
  END #end layer
Then, pass the ObjectID of the selected feature which needs to be hilited
to the new layer in map file..

Hope it helps.

cheers !
