QUERY NSS
Messages
userid1 userid2 userid3 ...
is a list of the user IDs of the users who are using the NSS or saved segment.
In the display for a segment space and its members, the space itself and some
members may not currently be loaded by any user. In that case, the list of users
is replaced by the word NONE.
Notes:
1. A user ID of SYSTEM in the response means that part of the CP system is
using the DCSS or NSS. There can be multiple parts of the CP system
using a DCSS or NSS at the same time. Therefore, the response to QUERY
NSS USERS could have SYSTEM listed more than once.
