When no one is logged on to the NT, the Log Off screen displays up to
six objects per NCM, including system ID, current data, and status. The
screen refreshes every 20 seconds. You can add objects to this summary
with the HOLD command and delete objects with the CLEAR command. Hold Summaries
The HOLD and CLEAR commands are available for every object type.
When an object is commanded to HOLD, the CLEAR command replaces
HOLD on that object’s screen.
To display an object on the Hold Summary, select a system, an object,
and HOLD. If you try to add more than six HOLD objects to the
summary, the NT displays the error message
