setting STYLE with CGI parameters

[Brock Anderson]

Thanks Paul.

Near the bottom of this page:

    http://mapserver.gis.umn.edu/docs/reference/cgi/controls

it says if there is only one class, then omit the index.  I actually 
have the CGI parameters working to set outlinecolor directly within the 
class.  I use a query string parameter like this:

    &map_mylayer_class_outlinecolor=...

I just can't seem to get into the STYLE elemen to set WIDTH.
