There is a real  issue. HPO5 has been plagued by  a significant amount of
spool  problems and,  even today,  there are  sites whose  PEERS NAMES  I
cannot update because  of a bug in  the RDR command that  does not always
recognize NETDATA files  as being what they are, and  of course a NETDATA
file processed  as if it were  in PUNCH format tends  to generate invalid
commands. I  have another case  where spool files  mysteriously disappear
from LISTSERV's  reader, and a  lot of  cases where the  TRANSFER command
doesn't work  because LISTSERV has class  D and a bug  (fixed since then,
but  the fix  is not  always  installed because  of the  myriad of  other
pre-reqs) made it  mandatory to do 'TRANSFER  your-own-userid RDR' rather
than 'TRANSFER RDR' when you have the privs to affect other userids.
