I have question.  Is there any chance that you stop wasting the time of 
people on this list by either doing your own research or trying things 
at an interactive prompt?  Or are you now well past that point, as 
you're learned that the extremely generous people here have fitted your 
bibs, spoon fed you and and changed your nappies so many times that it 
has rendered you incapable of doing anything for yourself?
