   Over and above Frank's excellent comments, I'd like to point out that the   
   two lines I've cited above probably don't do what you think they do.   
      
   You've already been reading the file to exhaustion, so myobject's state   
   is now "fail" (that was the reason your first loop terminated) and "eof".   
      
   Neither closing nor re-opening a file on myobject will change that state   
   (open() will either leave an object's state as it found it or will add   
   "fail" and/or "bad" into its state).   
      
   Therefore it is guaranteed that your second loop will never run.  The   
   object is already at "eof" so the test fails immediately.  If you   
   switch to the correct loop construct (as Frank advised), you will   
   find that no input will be performed because myobject is still in   
   the "fail" state.   
      
   Before re-using the file object, you *must* reset its internal state   
   to that of an unused stream: do this by calling myobject.clear()   
   after closing the file and before re-opening it.   
      
   Regards,   
   Tony.
