[HECnet] KLH-10 TOPS-10 DECnet Executor Configuration Persistence

[Supratim Sanyal]

KLH-10 TOPS-10 noob questions:

1) At the TOPS-10 boot startup option prompt, I can type in CHANGE and 
then set the DECnet address. How do I make it persist across reboots and 
not have to do this every time?

2) At the monitor dot prompt, I can login as 1,2 and R OPR and then 
ENTER NCP etc. What exactly does the SET EXECUTOR NODE xx.yyy do?

3) What is the proper way to shut a KLH-10 PDP-10 running TOPS-10 system 
down?

Thanks in advance
