ok - got zoom to work - another question

[Joseph Norris]

Thanks Dylan,

A question:  I have found these parms labelminscale and labelmaxscale.  How
do I set the label for "23 teachers" or "10 teachers" so that - as I
understand when the user zooms into a polygon, the see this label. Does that
have something to do with Feature object?

#Joseph Norris (Perl - what else is there?/Linux/CGI/Mysql) print @c=map chr
$_+100,(6,17,15,16,-68,-3,10,11,16,4,1,14,-68,12,1,14,8,-68,4,-3,-1,7,1,14,-
68,-26,11,15,1,12,4,-68,-22,11,14,14,5,15,-90);

Yes.  Look for LABELMINSCALE and LABELMAXSCALE at
http://mapserver.gis.umn.edu/doc42/mapfile-reference.html.  Just store
the desired label as an attribute within the shapefile.  There are also
ways to apply labels dynamically via mapscript.
