We are working on a new design for UDFs in v2.0, but it has not been implemented yet. My original post announcing v2.0 (dated 25 January 2008) discussed this limitation. For regridding, you can try using the lterp() function, which used to be a UDF but is now built into GrADS 2.0. <div>Jennifer</div><div><br><div><br><div><br><div><div>On Nov 3, 2008, at 9:30 AM, Bernd Becker wrote:</div><br class="Apple-interchange-newline"><blockquote type="cite"><div style="margin-top: 0px;
