console, you can enter CP commands, such as loading (IPL) an operating system.
The virtual console is the device an operating system views as its system or
hardware console.
Note: The key assignments for your keyboard might differ from standard key
assignments. Some 3270 emulators allow you to remap the key assignments;
for example, the Clear function might be assigned to the ESC key on some
keyboards and the Pause/Break key on others. Consult your display
documentation for key mappings.
As you do work on your console, the lower right corner of the screen displays
various status notices. The notices tell you what is happening in the system at the
present time. If you forget what these notices mean, you can come back to this
section for reference.
CP READ
This notice means that the Control Program (CP) is waiting for you to
enter a command.
VM READ
This notice means that a virtual machine operating system, such as CMS, is
waiting for you to enter a command.
RUNNING
This notice means the virtual machine is working on something. For CMS,
this means CMS is ready for you to enter a command.
MORE ...
This notice means that there is more information than can fit on the
current screen. After a pause (which depends on the terminal settings for
your virtual machine), the next screen of information is displayed. To view
the next screen right away, press the Clear key. To hold this information on
the screen, press the Enter key, which changes MORE... to HOLDING.
HOLDING
This notice means the system is waiting for you to clear the screen before
showing you more information. The notice appears when the screen
displays MORE... and you press the Enter key. The notice can also appear
when another user sends you a message. To cancel the hold, press the
Clear key.
NOT ACCEPTED
This notice means that the system is working on something and is too
busy to accept another command. Wait several seconds and issue your
command again.

CP commands
CP provides you with commands that allow you to view and manipulate your
virtual hardware (virtual CPUs, virtual storage, minidisks, and other devices). To
issue some CP commands, you need to be in a special privilege class assigned to
you in the user directory. Privilege classes are denoted by the letters A through Z,
the numbers 1 through 6, or the word "Any." For the tasks explained in this
document, the user IDs you use have all the required privilege classes (like
superusers in Linux).
