  KI_tag_list_list         *events         --- their bulletinning events
  KI_int_nitems            *nents          --- length of the above lists

 <KI_int_nitems>           *nopts          --- no of control options
  KI_cod_error             *ifail          --- error code


Description:
  OUBBCO outputs the state of the bulletin board's controls in the same form as
  data is supplied to SEBBCO to set the state, except that arrays are replaced
  by lists. See SEBBCO for more information.

  Thus each list in the list 'events' indicates which events are being recorded
  for entities of the type whose code is given in the corresponding position in
  the list 'ents'.

  The list 'opts' contains option codes which indicate further information
  about the state of the bulletin board.  The presence of a code in 'opts'
  indicates that the current state of the bulletin board is the state that the
  board would be in after a successful call to SEBBCO supplying the given code
  in 'opts'. In particular, precisely one of BBOPOF (indicating that the
  bulletin board is off), BBOPON (bulletin board will record tags but not any
  user field data) and BBOPUF (bulletin board will record tags and user field
  data) will be present in 'opts'.
