In addition to having record attributes showing a format of Stream,
it must actually be in stream format, i.e. it must actually contain
the <CR><LF> between each line.  So it doesn't do any good to just
   $ set file/attributes=rfm=STM,
you need to convert the file to stream (or create it that way in the
first place.)  The easiest way to do that is to use convert/fdl with
a .fdl file specifying (from TCPWARE:STREAMCRLF.FDL):

IDENT   "28-OCT-1991 13:22:18   VAX-11 FDL Editor"

         SOURCE                  VAX/VMS

         BEST_TRY_CONTIGUOUS     no
         CONTIGUOUS              no
         NAME                    ""
         ORGANIZATION            sequential

         BLOCK_SPAN              yes
         CARRIAGE_CONTROL        carriage_return
         FORMAT                  stream
         SIZE                    0

(Example .FDL file courtesy TCPware.  There's no copyright in it, so
I assume I can post it here.)

On the other hand, it *might* be possible to get coerce the Samba
server into converting Seq Var files to Stream on the fly, much as
the POP, IMAP, FTP, NFS and Apache 2.1 servers do.  I've messed
around a little with Samba, but am certainly not an expert...
Does anyone else know for sure if this is possible.
