Klemens,
Here are the updates for today.
I have rewritten the command file indmak01
using curses. It is more elegant now.
I have not had time to include the duplicate registration check.
Will probably do that tomorrow.
The /etc/brc files on the separate floppy must be
tarred in under root.
I have added the ' -y ' flag to the /etc/fsck
command in the brc file,
I presume b stands for boot,
r for root,
and c for command: brc, but I don't really know.
All these files are in /etc
I have not had a chance to observe 
the -y flagged fsck functioning,
since booting only occasionally leads to major file system changes.
However, I had no trouble booting with the new version.
I have retained the old one in a brc.back up file,
but if brc itself didn't work,
the backup file would most likely be inaccessible.
.PP
I have included a new shell command file "autostart"
in the .login sequence.
autostart, which lives in lib/shells,
tests for the presence of a file
which I have called /usr/spool/uucp/LCK..mcu.
If this lock file is present, autostart does nothing
but echo that the blood pressure monitors are active.
If this lock file is absent, autostart calls startall
and invokes the cmd000 files which 
in turn connect mcu to the asy ports.
Since I don't have any asy ports I could not demonstrate
this routine, but the error messages announcing the absence
of asy ports come through clearly. Having openened the ays
ports, autostart writes the lockfile, 
so that subsequent executions of .login
merely announce that the monitors are active.
When the computer is turned on,
the root /etc/rc program which is invoked with every boot
erases all the /usr/spool/uucp/LCK files,
giving autostart the chance to do its thing.
This is all automatic, and you needn't mention it to the nurses at all.
.PP
The shut-off procedure however is not to difficult either.
All that you have to teach them,
when they are ready to turn the computer off,
is to type "bye" ENTER.
bye is a shell file (in lib/shells) which generates a date stamp of the
format 930406, and prepends this string to the file*, file06, file10, etc.
and index of arch00 and concatenates these files >>! in arch01.
(If bye were invokes twice, the respective files would be double,
but it would be a trivial matter to sort them with the -u flag.)
bye then issues a few 'sync' commands, and displays a lib/text/bye_text
good night message.
.PP
I hope it all works.
Let me know.
