David,
 
  I am sorry  I could not reply sooner  to your mail. I wrote  down the problem
you described and have  now implemented a solution for it,  but since your mail
was on my first screenfull of spool files (which I never look at :-) ) I forgot
to tell you about it.
 
  Anyway, when release 1.5c is distributed you will be able to store lists from
your  MVS system  by  means of  the  PUT command,  with  the following  syntax:
 
//DUMMY JOB whatever
/*XMIT CANADA01.LISTSERV DLM='XXX'
PUT vector-l LIST PW=listpassword
*
* IBM 3090 vector processors
*
(etc)
XXX
 
  No // JOB nor  // EOJ card should appear in the dataset  as it is transmitted
to LISTSERV. Note that the list file  must have been obtained by a GET listname
command, not REVIEW  listname, otherwise the store operation  will be rejected.
 
  This process  will purposefully not  work with mail.  The reason is  that the
list file as  sent by a GET  command may contain 'flags' in  columns 81-100 (eg
distribution options  for the various  users) which the mailer  would truncate.
It is therefore not desirable to allow  lists to be stored from mail-only nodes
-- I would  get 'bug reports'  from users  that there distribution  options are
trashed because  the owner  destroys them  everytime he  stores the  list (This
was to answer a question from someone else).
 
Regards,
         Eric
