  17. Mary,
  18.  
  19. If I want to copy from a text reader to a string, would the following loop
  20. be both OK and efficient?
  21.  
  22. FW_CString string;
  23. while (reader->GetPosition() < reader->GetByteCount)
  24. {
  25.         FW_LChar ch = reader->GetCharacterAndAdvance();
  26.         string.Append(ch);
  27.         if (ch == chTab || ch == chReturn)
  28.                 break;
  29. }
  30.  
  31. Also, why do you allocate the reader with the FW_NEW operator instead of
  32. allocating it on the stack?
  33.
