symbology question

[Richard Greenwood]

Bart's SLD suggestion below is an excellent approach if you are
working in a WMS environment.

If you are working with mapscript, it is easy to alter the styles.

If you are working with the CGI interface, you can over-ride map file
parameters with CGI variables like this:
   MAP_layerName_className_SYMBOL=xyz
The default symbology would be defined in the map file, and then
over-ridden with a CGI item=value pair(s) as needed. Refer to the "CGI
Variables" section  of the "CGI MapServer" documentation.
