Summary: Why NOT use the user data area

DEC documented the user defined area in the VMS 2.x documentation.  In an
early release of VMS 3.x they specifically undocumented the feature.  The
wording was something like "we did document it but we never should have."

There is no user defined area in the UAF, in spite of what the file description
might lead you to believe.  DEC has $GETUAI and $SETUAI to fiddle with the
UAF.  If you don't use these system services you will probably run into
trouble later on in life.
