select the STYLE based on the SCALE (which sounds like what you want to do),
but you may consider constructing a few separate copies of your layer, each
with a different point size, and restricted to display over a certain range of
map scales, using MINSCALE and MAXSCALE settings on each of the layers.</span></font></p>

Dear Faldor,<br>
<br>
<snip>What I need is to have the points grow to cover all space available<br>
when I zoom in.</snip><br>
<br>
Do you mean that the size of points should grow? It can be done easily by<br>
setting proper SIZE in the STYLE tag.<br>
<br>
<br>
Regards,<br>
Ambastha</span></font></p>
