First way:
Directly use <% %> to write script code in it, for example
<%
Response.Write classic Hello word!
%>
Second way:
Indirectly using <SCRIPT></SCRIPT> tags
<SCRIPT LANGUAGE=VBScript RUNAT=Server>
Response.Write classic Hello word!
</SCRIPT>
BTW: There are two scripting languages for writing ASP, namely VBScript and JavaScript!
