Dear All

I wonder if mapserver can display certain layer by the scale of current map.
For example, when scale is bigger than 1/500 the map showes
layer A,when scale is smaller than 1/500 then the map hides layer
A.
Is it to edit the map file to achieve?If yes, what variable should I modify?

Thanx!!!
