/*
  Mechanism for building lists of arbitrary NML messages, used by
  the canonical interface and interpreter to pass planned sequences
  to the HME.

  Modification history:

  25-Jun-2001 made commandbuf part of a union and add dummy variable
  to ensure alignment.
  25-Jul-1997  FMP changed line number stuff;
  changed MAX_EMC_NML_COMMAND_SIZE to MAX_NML_COMMAND_SIZE (I'm trying
  to get the EMC prejudice out of here)
  22-Oct-1996 WPS attempted to fix alignment problems by moving the
  command member of NML_INTERP_LIST_NODE to the begining of the structure.
  16-Nov-1995  Fred Proctor created
