How to read Array of Strings (JS)

I've been working on importing a text file to instantiate an initial set of objects. So far it's been working OK but now I want to randomise the starting locations of the cube objects.

 function Spline(){     
 var separator1 = "\n";
 var separator2 = ",";
 var dataArray: String[];
 var line: String[];
 
 
     var fileText = File.ReadAllText("Assets/ObjectEditor.txt");
     line = fileText.Split("\n"[0]);
     var savedObj:GameObject = null;
     var objCount = 0;
     var randCube = new Array ();
     for(var i = 0; i < (line.Length); i++) {
         dataArray = line[i].Split(","[0]);
         var posX = (parseFloat(dataArray[1]));
         var posY = (parseFloat(dataArray[2]));
         var posZ = (parseFloat(dataArray[3]));
         var objRotationX = (parseFloat(dataArray[4]));
         var objRotationY = (parseFloat(dataArray[5]));
         var objRotationZ = (parseFloat(dataArray[6]));
         var objID = ((dataArray[7]));
         if ((dataArray[0] == "Cube")) {
             savedObj = Cube;
            randCube.Push(line);
            Debug.Log(randCube);
         }
 
         if ((dataArray[0] == "Blank")) {
             savedObj = Blank;
         }
 
         // Spawn Object
         var obj = Instantiate(savedObj, Vector3(posX, posY, posZ), Quaternion.Euler(objRotationX, objRotationY, objRotationZ));
         objCount++;
         obj.name = (dataArray[0] + "");
          if(savedObj == Cube){
              var tm : TextMesh = obj.GetComponentInChildren(TextMesh);
              tm.text = objID;
              
               obj.GetComponent(CubeScript).CubeID = (parseInt(objID));
           }
       
           if(savedObj == Blank){
              obj.GetComponent(BlankTrigger).trigger = (parseInt(objID));
          }
     }
 for (var X = 0; X < randCube.length; X++) {
 var zombie : String[] = randCube[X];
  
         Debug.Log(randCube.length + ' length' + zombie);
     }
     //
 }

I've been trying to put lines that start "code" (dataArray[0]) into an Array which I can then randomise and instantiate separately to the Blanks. The problem is when I try and read randCube[x] I just get "System.String[]" repeated x amount of times.

And idea how I can import and export the lines without having to use process separate text files?
