How to rewrite the saveData function

Here is the function that is called after hitting the save button:

{geshibot lang="javascript" head="saveData"}flashblocks.saveData = function () {
     TXTSEP = "\t";
     OBJSEP = "\r";
     mod.msg.text = lng.saving;
      dark._visible = true;
     mod._visible = true;
     var theData = "";
     for (n=0; n<storeData.length; n++) {
          var dataLine = "";
         if (n>0) {
             dataLine += OBJSEP;
          }
         dataLine += String(storeData[n].id)+TXTSEP;
         dataLine += String(storeData[n].mc)+TXTSEP;
          dataLine += String(storeData[n].objType)+TXTSEP;
         dataLine += String(storeData[n].link)+TXTSEP;
         dataLine += String(storeData[n].param)+TXTSEP;
          dataLine += String(storeData[n].theContent);
         theData += dataLine;
         // trace("save: "+dataLine);
          // 0   id  1 mc  2 objType   3 link  4 param   5   theContent;
      }
     result_lv = new LoadVars();
     result_lv.onLoad = function(success) {
         if (success) {
              startSaveDone(this.writing);
         } else {
              mod.msg.text = lng.error_server;
         }
      };
     // 
     send_lv = new LoadVars();
     send_lv.theData = theData;
     send_lv.theFile = mod.dataFile.text;
      send_lv.sendAndLoad(config.flashblocks_path+config.flashblocks_saveData_file, result_lv, "POST");
 };{/geshibot}
