How to set javascript variables using MVC4 with Razor

Can someone format the code below so that I can set srcript variables with c# code using razor?

The below does not work, i've got it that way to make is easy for someone to help.

@{int proID = 123; int nonProID = 456;}

<script type="text/javascript">
    @{

     <text>  

    var nonID =@nonProID;
    var proID= @proID;
    window.nonID = @nonProID;
    window.proID=@proID;

    </text>
}
</script>
