On VMS there was an easier way to transfer files via
kermit and still retain the files' attributes.
The tecnique involved using VMS' backup utility to
create a backup file save set with a record length of
8192 bytes and group=0 (no redundancy groups). You
transfer that file over to the other system in fixed
file mode - the result is a 512 byte record length
binary file.
You then on that system create a small backup save set
with the same record size of 8192 bytes, and use
copy/overlay to copy the transferred file over that
newly created backup saveset. Viola, VMS recreates
the file from the first system with the proper record
structure, and you can then use backup/restore to get
the files you transferred out and put them to use.
With slightly more recent versions of OpenVMS you don't have
to do the copy/overlay trick, you can use the set file
command to change the file attributes instead. Before this
functionality was added there were programs around that
allowed you to "fix" backup savesets that had been transferred
via kermit (or ftp for that matter).
