Library /sys$common/syshlp/uafhelp.hlb Usage Summary  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    To invoke AUTHORIZE, set your default device and directory to
    SYS$SYSTEM and enter RUN AUTHORIZE at the DCL command prompt. At
    the UAF> prompt, you can enter any of the AUTHORIZE commands.

    To exit from AUTHORIZE, enter the EXIT command at the UAF> prompt
    or press Ctrl/Z.

    If you move the SYSUAF.DAT file, be sure the logical name SYSUAF
    is defined and points to an existing file. If AUTHORIZE is unable
    to locate the SYSUAF.DAT file, it displays the following error
    message:

    %UAF-E-NAOFIL, unable to open SYSUAF.DAT
    -RMS-E-FNF, file not found
    Do you want to create a new file?

    A response of YES results in creation of a new SYSUAF file
    containing a SYSTEM record and a DEFAULT record. These records
    are initialized with the same values set when the system was
    installed.
