What can I do with this system value?

You can view or change the system part of the library list. The list can contain as many as 15 names. When searching for an object in the library list, the system searches the system libraries before searching any user libraries. A library specified as part of the system library list cannot be deleted or renamed when the system is fully operational.

The QSYS library cannot be removed. The libraries must exist in the system disk pool or in a basic user disk pool.
