                    <htmlb:page title = " ">
                    <htmlb:form> 

<html>
<page>
<FORM NAME="formlist">
<table border="0" cellpadding="0" cellspacing="0">
<tr>
    <td align="RIGHT">
        <INPUT TYPE="TEXT" NAME="keywords" size=60>
        <INPUT type="submit" name="OnInputProcessing(search)">
    </td>
<% data: it_ekko type standard table of ekko initial size 0,

       from ekko
       into table it_ekko.

    <td><SELECT NAME="typelist">
        <% loop at it_ekko into wa_ekko. %>
        <OPTION VALUE="<%=sy-tabix%>"><%=wa_ekko-ebeln%>
