you forgot ToString[] actually you need StringReplace[ToString[CForm[ yourexpression ]],"Power"->"Math.pow"] Regards Robert -- --- Robert Nowak (robert.nowak at ims.co.at) IMS Nanofabrication GmbH A-1020 Wien, Schreygasse 3, Austria Phone: (+43 1)2144894-32, Fax: (+43 1)2144894-99 "Albert Retey" <albert.retey at visualanalysis.com> wrote in message news:9v49e4$n0p$1 at smc.vnet.net... > "Matthew D.
