Response.Write "<OPTION value="""" SELECTED></OPTION>"
Response.Write "<OPTION value=1>One</OPTION>"
Response.Write "<OPTION value=2>Two</OPTION>"
Response.Write "<OPTION value=3>Three</OPTION>"
Response.Write "</SELECT>"

Just be careful when you are proccessing the response that they have
selected an actual value, rather than the blank one.

If you include the following javascript function within the <head></head>
section, and call it from the form as shown, Javascript will check for a
selection before allowing the form to submit. Note that, if Javascript is
disabled, this won't work, so you MUST also check server-side.

Javascript:
function CheckForm(objForm){
if(objForm.select1.selectedIndex == 0){
alert("You must select an option from the select box.");
return false;}
}

HTML:
<form onSubmit="return CheckForm(this);">

Hope this helps - note that its after midnight here, I'm tired and I wrote
the script off the top of my head and haven't checked it - it *should* work
but I take no responsibility...

As far as I am aware, that cannot be done. Try the way I suggested before.

Such a thing is implementation-specific. You might be able to find such a
solution for a small range of browser/OS combinations, but you will have no
guarantee of forward compliance. Consider this, from the HTML 4 spec:

"Visual user agents are not required to present a SELECT
element as a list box; they may use any other mechanism,
such as a drop-down menu."
http://www.w3.org/TR/html401/interact/forms.html#edef-SELECT

The spec merely requires that the SELECT element creates a "menu". It leaves
the details to the implementation.

What exactly are you trying to accomplish? There is certainly a simpler
solution.

Yes, what Peter said. By using them, you can have NONE selected by default,
unlike what you can do with a select, but you'll then have no value, just
like if you had an empty leading spot in the select.
