You may recall that older computers didn't have a way to programmatically power 
themselves down.

VMS is one of those systems.

When you shutdown a VMS system it closes all files and cleans up everything 
going on in the operating system then it displays a message which says 
something like "SYSTEM SHUTDOWN COMPLETE - USE THE CONSOLE TO HALT THE SYSTEM" 
and then it goes into an infinite loop with interrupts disabled.  The simulator 
detects this condition which will never produce useful results from the 
simulated system again without operator intervention and allows you to do that.

Would you want it to behave differently?

Subject: [Simh] error

    After using shutdown on my virtual VMS, it dropped to the simh prompt and 
had this error.

Infinite loop, PC833DC8D3 (BRB ...)
and the same hex number were the ... is. What does that mean?

Bill
