<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex;">Create a layer in your mapfile like so:<br>
<br>
SYMBOL<br>
NAME 'circle'<br>
TYPE ELLIPSE<br>
FILLED TRUE<br>
POINTS 1 1 END<br>
END<br>
<br>
LAYER<br>
NAME 'myPoiint'<br>
TYPE POINT<br>
STATUS OFF<br>
CLASS<br>
STYLE<br>
COLOR 255 0 0<br>
SIZE 15<br>
END<br>
END<br>
END<br>
<br>
Then in your script, the steps would be like so:<br>
<br>
1) get the 'myPoint' layer<br>
2) add a point feature to it<br>
3) set the STATUS appropriately<br>
<br>
Now draw as normal. Assuming the point is in map coordinates you should see a red circle at the location<br>
you specified.<br>
