<SCRIPT>
function displayNx (number, factor)
{
 window.document.open()
 window.document.writeln("<TABLE BORDER=2>"); 
 for (var i=1; i<number; i++) 
   {
   window.document.writeln
   ("<TR><TD>",i," x ",factor," = </TD><TD>",factor*i,"</TD></TR>") 
   }
 window.document.writeln("</TABLE>"); 
 window.document.close()
}
</SCRIPT>

<BODY>

<FORM>
<INPUT TYPE="button" VALUE="click here" ONCLICK="displayNx (15, 13)">
