1    /CONFIRM

       /CONFIRM
       /NOCONFIRM

    Prompt for positive confirmation before carrying out the
    indicated operation. When wild cards are not used, /NOCONFIRM
    is the default. When wild cards are used, /CONFIRM is the default
    and a prompt is issued for each account to be operated upon.
    Moreover, when wild cards are used, /NOCONFIRM causes only a
    single prompt to be issued-it does not eliminate the prompt
    altogether.

2    /GROUP

       /GROUP=name

    Name of a management group to constrain the operation to. This
    qualifier can be used in conjunction with a username parameter
    containing wild card characters so as to further constrain the
    delete operation.

3    /LOG

       /LOG
       /NOLOG

    When the operation is successful, output a status message stating
    that the operation succeeded. Note that error messages are always
    indicated. /NOLOG is the default behavior unless wild cards are
    used in which case /LOG is the default.

4    /MESSAGES

    When the /MESSAGES qualifier is specified, only the user's
    messages are deleted or returned. The account itself is not
    deleted.

5    /PROMPT

       /PROMPT (default)
       /NOPROMPT

    By default if a wildcard is used, even if /NOCONFIRM is
    specified, one confirmation prompt is issued. If /NOPROMPT is
    specified, there is no prompting at all.

6    /RETURN

       /RETURN
       /NORETURN (default)

    When /RETURN is specified, unread messages are returned to their
    originator as undelivered. By default unread messages are deleted
    without sending a non-delivery notice back to their originators.
