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

  UAF> DEFAULT /DEVICE=SYS$USER/LGICMD=SYS$MANAGER:SECURELGN -
  _UAF> /PRIVILEGES=(TMPMBX,GRPNAM,GROUP)
  %UAF-I-MDFYMSG, user record(s) updated

      The command in this example modifies the DEFAULT record,
      changing the default device, default login command file, and
      default privileges.
