WHO is a utility designed to output useful information about a user if a
username or UIC is known.  It was originally modelled on the Digital program of
the same name which was eliminated during the summer of 1982, but it now
provides much more information than the original program.

ATTENTION:  WHO accesses the authorization file directly via RMS rather than
using the $GETUAI system service in order to support the wildcard and UIC
searches it provides.  Because the layout of the UAF is not guaranteed to
remain stable, this program may break at VMS upgrades.  It is known to work
under all versions of VMS V5 through V5.4-2 (with CAPTIVE/RESTRICTED
interpretation of VMS V5.4, as explained in the documentation) and should work
with any version of VMS V4 without modifications.  Generally changes are
limited to adding support for an additional bit field, etc...  but you've been
warned...

The program includes a variety of security features, most of which are peculiar
to the Xerox sites where it is in active use.  Restrictions on account
visibility are documented at the top of WHO.PAS and are implemented in the
module ACCESS.PAS.  Fairly complete user documentation is contained in WHO.RNH.

The program contains support for our use of the local data area present in each
authorization record.  In the event that the local area is not used, or
contains different information, it will be ignored; the empty fields will not
be very noticeable, except perhaps in the /FULL output listing.

On the off chance that other sites are interested in utilizing the local data
areas, FIXUAF is a program which allows this area to be initialized and
updated.  I don't have documentation for it, but it is fairly short and
reasonably intuitive.

If you have questions, fixes, or enhancements, drop me a line.  I'm also
willing to listen to bug reports, but don't expect fixes, sorry... You can
