You are looking for the GetRef function.

From the link:

GetRef Function

Returns a reference to a procedure that can be bound to an event. ...

<SCRIPT LANGUAGE="VBScript">

Function GetRefTest()
   Dim Splash
   Splash = "GetRefTest Version 1.0"   & vbCrLf
   Splash = Splash & Chr(169) & " YourCompany 1999 "
   MsgBox Splash
End Function

Set Window.Onload = GetRef("GetRefTest")
</SCRIPT>
