This object contains an appropriate value to be used for
cOPatchIndex when creating entries in the cOPatchTable. The
value 0 indicates that no unassigned entries are available.
To obtain the cOPatchIndex value for a new entry, the manager
issues a management protocol retrieval operation to obtain the
current value of this object.
The agent will modify the value to the next unassigned index,
when a new row is created in cOPatchTable with the current
value of this object. After deletion of a row in cOPatchTable
the agent will determine through its local policy when its
index value will be made available for reuse.
