Thanks! Now I do not have to change SYS$SYSTEM:SHUTDOWN.COM

I'd be curious to know what you would do differently in either case.

I am trying to avoid having to create procedures outside of the normal shutdown
process. That way any upgrades or forgetting to use the proper procedure
(say as in an emergency reboot) will not affect the process.

Well, o.k., but I'm still wondering why a reboot differs from a
shutdown. Either way, everything stops.

In the procedure, @sys$system:shutdown, then you can control all variables.

I should ask you to go back and reread the thread, but in short, he
does not want to edit sys$system:shutdwn.com, so ther is no place to
put your code if he uses the symbols he has to invoke shutdown with
only the documented parameters.
I must be missing a post or two because I see no such prior stipulation

From the earlier posts, I thought it was SYS$SYSTEM:SHUTDOWN.COM that he didn't
want to change. In fact, this file should NOT be changed. As for
SYS$MANAGER:SYSHUTDWN.COM, this is the site specific shutdown file, specifically
for such modifications, and is preserved through an upgrade.
Caviet, I haven't touched this stuff on my VMS systems for 2 years or more, and
am subject to faulty memory.

Your use of terminology is not quite correct.
From what you are trying to achieve, whether you do a full shutdown or
one which has an automatic reboot makes no difference to you. In both
cases, the shutdown procedure executes fully. Whether the reboot is done
seconds after or hours later doesn't really make a difference.
In the local shutdown procedure, you can simply create your file whether
or not an automatic reboot was requested or not just after your software
was properly shutdown.
Then, in the local startup procedure (SYSTARTUP_VMS.com) you check for
the existence of this file. If it exists, it means that there was a
proper shutdown performed and you then delete the file and restart your
software , ortherwise, you perform whatever you need to do after an
improper system shutdown.
In fact, you might consider putting this login in your application's
startup and shutdown procedures. This way, if the application crashes
without the system crashing, the logic will be there when you restart
the app to realise that the application,s proper shutdown had not been called. |

Kind of looks like I have no choice.
I am trying to avoid having to create procedures outside of the normal shutdown
process. That way any upgrades or forgetting to use the proper procedure
(say as in an emergency reboot) will not affect the process.
As suggested by John Laird - "Edit it and pass as many of the Pn parameters as you need to syshutdwn.com ?
It's only a single line change and if you forget to check after your next
upgrade (if/when shutdown.com may change), you could have your site-specific
procedure write out something if any or all parameters are found to be
missing." Will probably be my only solution.

Therefore I can differentiate between a CRASH and a requested SHUTDOWN.
However it would be nice to differentiate between a REBOOT and a STANDALONE.
I could change the symbols (REBOOT and SHUTDOWN) to execute a command file to
do so but I would rather not.
Any ideas?

I wish it was that easy. The OPC$REBOOT logical is defined after SYSHUTDWN.COM
