/USER=user-spec

    Scans the UAF record for the specified user and creates the
    corresponding identifier. Specify user-spec by user name or
    UIC. You can use the asterisk wildcard to specify multiple user
    names or UICs. Full use of the asterisk and percent wildcards
    is permitted for user names; UICs must be in the form [*,*],
    [n,*], [*,n], or [n,n]. A wildcard user name specification (*)
    creates identifiers alphabetically by user name; a wildcard UIC
    specification ([*,*]) creates them in numerical order by UIC.
