And again with indentation
   private void doSaveAs(){
   //display file dialog
   FileDialog fDialog2 = new FileDialog (this, "Save As...",     
   FileDialog.SAVE);
      fDialog2.setVisible(true);
   //Set the file name chosen by user
   String name = fDialog2.getFile();
   // user canceled file selection, return without doing anything.
   if(name == null)
      return;
   fileName = fDialog2.getDirectory() + name;
   // Try to create a file writer
   FileWriter writer = null;
      try{
         writer = new FileWriter(fileName);
      } catch (IOException ioe){
      MessageDialog dialog = new MessageDialog (this, "Error Message", "Error writing the file: "+ioe.toString());
            dialog.setVisible(true);
            return;
   BufferedWriter bWriter = new BufferedWriter(writer);
   //Try to write the file
   StringBuffer textBuffer = new StringBuffer();
   try {
      String textLine = bWriter.write(2);
      while (textLine != null) {
         textBuffer.append(textLine + '\n');
         textLine = bWriter.write(name);
      bWriter.close();
      writer.close();
   } catch (IOException ioe){
      MessageDialog dialog = new MessageDialog (this, "Error Message", "Error writing file: "+ioe.toString());
      dialog.setVisible(true);
      return;
   setTitle("JavaEdit " +name); // reset frame title
   text.setText(textBuffer.toString());
}
