/USER=user-name

    Indicates the name of another user for whom you are setting or
    showing a forwarding address. You can use the /USER qualifier
    only if you have SYSNAM privilege. With the SHOW FORWARD command,
    there are two ways to show a user's forwarding address: you can
    specify the user name or you can use the wildcard characters (*
    or %) to search for names with a particular string in common.

    By default length of the user name is 31 characters long. Set
    Bit 5 of DCL_CTLFLAGS to avail this longer user name length of
    255 characters long.

                                NOTE

    Once this bit is set, user name length is set to maximum of
    255 characters long. Even if this bit is cleared, the behavior
    remains unchanged, that is, supports user name length of
    255 characters long, but there is no way to reset it to
    31 characters long.
