Library /sys$common/syshlp/mailhelp.hlb SET-SHOW, PERSONAL_NAME, Qualifiers, /ALL  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    Used with the SHOW PERSONAL_NAME command to allow a user with
    SYSNAM privilege to list personal name information set by
    other users or to display a message if a user has not entered
    a personal name. The /ALL qualifier is valid only when used with
    the /USER qualifier and works only with the SHOW PERSONAL_NAME
    command.
