line thickness with circle

[gerard barrington]

Dear list,

I am having a problem getting my line thickness adjusted to any size other
thanone pixel.
In my symbol file, I have the following symbol:

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

and in my map file I have a shapefile of type line that references this
symbol:

LAYER
        NAME "layer"
        TYPE LINE
        TILEINDEX "C:\layer.shp"
        STATUS ON
        CLASS
                STYLE
                        SYMBOL circle
                        SIZE 9
                END
        END
END

However, this gives me this error:

getSymbol(): Symbol definition error. Parsing error near (circle):(line 56)


Commenting out "SYMBOL circle" displays a single pixel line

Thanks for any advice,

Gerard
