DECC$UNIX_PATH_BEFORE_LOGNAME

   With DECC$UNIX_PATH_BEFORE_LOGNAME enabled, when translating
   a UNIX filename not starting with a leading slash (/), an
   attempt is made to match this to a file or directory in the
   current directory. If this is not found and the name is valid
   as a logical name in an OpenVMS filename, an attempt is made to
   translate the logical name and, if found, is used as part of the
   resulting filename.

   Enabling DECC$UNIX_PATH_BEFORE_LOGNAME overrides the setting for
   DECC$DISABLE_TO_VMS_LOGNAME_TRANSLATION.
