scale?

[Sears, Jeremy]

Hi All,
This should be an easy question, however I cant find information on it....
 
How does one display the scale of a map? Im looking to have mapserver (or
other means?) produce a scale like "1:50 000", rather than the scale bar. 
 
Thanks
Jeremy

Subject: [UMN_MAPSERVER-USERS] setting variable value in mapfile


Hello,

I know I can easily use variables in a mapfile, when the value comes from
cookies or a GET request.  But what about setting a variable inside the
mapfile itself?
Something like:

HIGHWAY_MAX_SCALE=2000000 
HIGHWAY_MIN_SCALE=90000

or

HIGHWAY_COLOR="255 250 115"

then be able to use something like:

COLOR  %HIGHWAY_COLOR% 

in a CLASS


That way if I decide I want to change a color, I can change it once, and
have it take affect for everywhere else? 

Thanks,


Jerl
