Filename of script usable in startup-script?

Hey guys,

i have this neat startup-script, and i'm wondering if it would be possible to use its filename as content of a variable?

#targetengine "session"
main();
function main()
{
 var myEventListener1 = app.addEventListener("beforeSave",  setMetadata, false);
 var myEventListener2 = app.addEventListener("afterSaveAs",  setMetadata, false);
 var myEventListener4 = app.addEventListener("beforeExport", setMetadata, false);
  var myEventListener5 = app.addEventListener("afterPrint", setCopys, false);
}
     
     function setMetadata()
    {
     app.activeDocument.metadataPreferences.author = "XXX";
      app.activeDocument.metadataPreferences.documentTitle = app.activeDocument.name; 
    }

As you see, I need to edit the author ('XXX') for every workspace the script is rolled out to.

My idea is to use the filename for that. This way I could prepare the scripts' filename and dont need to touch the content.

Is it possible to use fn for this, exspecially start-up scripts?
