Hi!

As far as I know if you set the layer status on really means you will be
able to turn it on/off. If the status is default you cannot turn the layer
off. So if you set the status on, you must set cgi variables.
Check layer, layers, <layer_name>_check and <layer_name>_select cgi 
variables in the cgi reference.

For example the itasca demo uses layer cgi variable to set some
layers on at start up.

demo_init.html from itasca demo:

<html>
<head><title>MapServer Demo Interface</title></head>
<body bgcolor="#FFFFFF">

<center><h2>MapServer Demo Interface</h2></center>
<p><hr><p>
Kattintson az <b>Indítás</b> gombra a demo elindításához.
Az adatok Itasca megyébõl (MN) származnak, fõleg a USGS 1:24000-es szelvényrõl.

<form method=GET action="/cgi-bin/mapserv">

<input type="hidden" name="map" value="/home1/www/maps/itasca/demo.map">
<input type="hidden" name="layer" value="lakespy2">
===================================================
<input type="hidden" name="layer" value="dlgstln2">
===================================================
<input type="hidden" name="zoomsize" value=2>

<input type="hidden" name="program" value="/cgi-bin/mapserv">
<input type="hidden" name="map_web_imagepath" value="/home1/www/maps/tmp/">
<input type="hidden" name="map_web_imageurl" value="/maps/tmp/">

<center><input type="submit" value="Indítás"></center>

</form>

<p><hr><p>

</body></html>

End of demo_init.html

I hope it helps

Bye
