I have a struct component
  for(i=0;i<1000;i++)
     {
        for(j=0;j<50;j++)
        {
           horiObjList[i][j].stX=0;
           horiObjList[i][j].stY=0;
           horiObjList[i][j].endX=0;
           horiObjList[i][j].endY=0;
           horiObjList[i][j].used=0;
          horiObjList[i][j].span=0;
         horiObjList[i][j].finished=0;

        }

     }

is there a simple way init it ?
thanks
