First you need to get your log, which will have been generated by a
vrml Script node, and placed in a field.
log = VRML.getNodeEventOut("MyScript", "MyLog");

Do you want to write it in a local file ? It will be difficult, for
security reasons ... But it's possible, using the FileSystemObject of
Internet Explorer :

<embed id=VRML ...>
<script>
fso = new ActiveXObject("Scripting.FileSystemObject");
f1 = fso.CreateTextFile("c:\\windows\\bureau\\testfile.txt", true);
log = VRML.getNodeEventOut("MyScript", "MyLog");
f1.WriteLine(log);
f1.Close();
</script>

If you want to copy your log into the clipboard :
window.clipboardData.setData('Text', log);

Bye

thanx alot, but this is not so much the prob. putting strings via
javascript is ok.
but i need to catch the informations out of the active vrml scene, like
user position, camerainfo, actions the user did etc....

You need to create a ProximitySensor, routed to a Script which will
receive the user position and orientation, and log that into a
SFString.
For the other informations you gave, you must implement this yourself
in your scene.

Now, a tip : if you want to display user position/rotation in the IE
status bar, press F8 (it works in Blaxxun Contact).
