Next, we begin adding data from the query to our page. We do this by calling the GetDataByName method, passing the name of the query element as a parameter.

This method call is enclosed in:
#( ... )#
characters, which indicate the presence of a Caché expression. When the page is generated, this expression is evaluated (in this case, the method is called) and the resulting value is added to the page.
<html> <body> 
<font color="#0000FF" size="+2"><b>Today's Top Picks</b></font>
<table border=0>
<csp:query name=FilmList classname="Film" queryname="TopFilms">
    <tr>
        <td>#(FilmList.GetDataByName("Title"))#</td>
        <td> </td>
    </tr> 
</table>
