KJOB is the command to use when you wish to leave the system.  Please
remember to KJOB when you leave since each job, even if it is inactive
uses system resources, such as a job slot (of which we often run out)
and core storage in the monitor's data area.

You may simply type the letter K followed by carriage return.
This command runs the LOGOUT program.

For information about various LOGOUT options, read the file
