Description 

In my opinion it would be a nice enhancement to be able to define variables in
your MAP file which you can use throughout the MAP file.

E.g.
DEFINE WMS_URL "http://www.vz.geodan.nl:8080"

LAYER
  CONNECTION "%WMS_URL%/ms4w/apps/zeegras/map/zeegras_server.map&"

Or any other syntax. This can lighten configuration. Ofcourse this can be done
by using a scripting environment, but not everybody wants to use a scripting
environment to get this done.

Thoughts?

Interesting idea. Personally I think it's more useful to control variables like 
that from outside the mapfile than within. That is, pass in WMS_URL as a 
variable via the CGI program. That support is already there for a limited 
number of elements such as DATA, CONNECTION and EXPRESSIONs.

It's worth leaving here as a feature request though cause it may be real easy 
to add later...

Hi Steve,

this especially comes in handy when using MAP files as the configuration file
for Chameleon. These MAP files are read by php_mapscript and determine which
layers will be present in the Chameleon application.
