/CONFIRM
       /NOCONFIRM (default)

    Controls whether the STARTUP REMOVE command displays the file
    specification of each file before deleting its record in the
    startup database and requests you to confirm that the file be
    deleted. If you specify /CONFIRM, you must respond to the prompt
    with a Y (Yes) or a T (True) and press Return before the file
    is removed. If you enter anything else, such as N or No, the
    requested file is not removed.
