* '''void display(int fn = 0)const;'''<br />
If '''fn''' is OT_CLR_AND_DSPLY_ALL_CLR_AND_DSPLY_ALL, then it will check to see if _owner is not null. If _owner is not null, it will call the _owner's display() with OT_CLR_AND_DSPLY_ALL_CLR_AND_DSPLY_ALL, otherwise it will just clear the screen.<br />
Then it first call IOFrame::draw() and then it will display all the _fld elements, one by one.
If '''fn''' is OT_DSPLY_ALL _DSPLY_ALL then it will just call IOFrame::draw() and then it will display all the _fld elements, one by one.<br />
If '''fn''' is greater than 0 then it will only display '''_fld''' number '''fn''' (_fld[fn-1])
* '''IOField& operator[](unsigned int index);''' returns the reference of the _fld[index], if index is larger than _fnum, then circle back from the beginning.<br />
