Well, it is enough to open both MVS System Commands and JES2 Commands

OBEY is not exactly the system command, however it is widely used.
My favourite is QUIESCE.
There are also other commands which I (almost) never use, but I

Ive always thought the TCPIP OBEY command was a security exposure. Someone
could reconfigure TCPIP using their private data set. Yes you can lock
down the command.
I think VTAM is better, you can only activate a member which is in the VTAM
VTAMLST dataset concatenation - and so you have to use
There are some MVS commands that are hard to understand how and why they
were created. What bothers me is the fact that the input of the commands
that modify MVS behavior allows input from private dataset. These are the
