Try taking var map out of the load function and making it a global variable.

<html>
<head>
  <title>Test</title>

  <style type="text/css">

        #map{
                width:100%;
                height:600px;
                border:1px solid;
        }
</style>

    <script src="http://openlayers.org/api/OpenLayers.js"></script>

         <script  defer="defer" type="text/javascript">

var map

function load(mode){

        if (mode=="start"){

        ...
        .
        .
               map = new OpenLayers.Map('map',options);

                var wms = new OpenLayers.Layer.WMS(...
                .
                .
                .

                map.addLayer(wms);

                map.zoomToMaxExtent();
                //map.setCenter(new OpenLayers.LonLat(145,-40),8);//here
would be know error!

        }
        else if (mode=="newPos"){
                map.setCenter(new OpenLayers.LonLat(145,-40),8);//-->error:
map is undefined!
        }

}

      </script>

    </head>

    <body onload="load('start')">

        <table width="100%" border="0">
                <tr>
                        <td colspan="2" height="100">TITEL</td>
                </tr>
                <tr>
                        <td width="20%">
                        <input type="button" value="Go"
onClick="load('newPos')">
                        </td>
                        <td><div id="map"></div></td>
                </tr>
        </table>
    </body>
