All this 'good' traffic about 'SHUTDOW', 'SYSSTOP', 'UPS...', etc.. served
as a reminded of a question that I asked some months back and never got an
answer:
     Is there a way after a reboot to determine if we are trying to recover
from a system failure versus a reboot due to some system upgrade. (There may
be additional tasks to perform in the first case).

If we are 'pushing' for a 'shutdown command script' to be added to the list
of Customer Funded Enhancements then I'd like to also include some mechanism
for distinguishing restarts due to system failures.

....  and at first glance seems to me to offer more flexibility;  and
would perhaps make it easier to add additional "features" in the
future ??....   blue-sky example of part of a background job that I
would like to be able to run as OPERATOR.SYS someday soon:

!.......
!SETVAR HPAUTOCONT TRUE
!WHILE  <UPS has enough battery left and room temp O.K.> DO
!PAUSE <whatever seems appropriate>
!DOEND
!SETVAR TIMETOSD <# of seconds of battery remaining>
!SETVAR TIMETOSD TIMETOSD - <some safety factor>
!comment  YIKES !!...  losing power or overtemp.... shutdown !!
!WARN <the world>
!STREAM  JBGRACFL.SYSOPER (graceful SD:  stop logging, etc.)
!PAUSE !TIMETOSD; JOB="GRACFL,OPERATOR.SYS"; EXISTS
!SHUTDOWN  (Stan's above)
!EOJ

It is a bit embarrassing that the only way for MPE to respond to a
message from an UPS (HP or any other, AFAIK) is to crash the
O.S.  Since the code to actually *do* a shutdown is already there
to be executed on a =SHUTDOWN from the CONSOLE, seems
like it shouldn't be a huge task to put a regular MPE command
"header" on that same code (restricted to MANAGER and
OPERATOR.SYS and maybe ALLOW list, of course)...  We have
:RECALL & =RECALL;  why not :SHUTDOWN & =SHUTDOWN..

....  add my name to the <plug> list for putting this on the SIGMPE
or SIGSYSMAN enhancement wish list.....  maybe this is a another
good candidate for the next round of Customer Funded Enhancements
(CFE)  ??..
