You can use @ processing directives in your scripts to send information to IIS about how to process an .asp file. For example, the following script uses the @LANGUAGE processing directive to set the scripting language to VBScript.
<%@Language=VBScript
Dim myvar
Application("myvar") = This is my var
Response.Write(myvar)
%>
The following five @ directives are supported by Active Server Pages (ASP) in IIS 4.0.
