The following list controls cannot be updated using WRITE_LCONTROLS. They are updated automatically by list services:

• The current number of list entries or data elements on the list (choice is determined by the value of LISTCNTLTYPE as described above). This field is initialized to zero when the structure is allocated.
• The approximate number of times the list has changed from empty to nonempty. This field is initialized to zero when the structure is allocated.
• The number of list monitoring information entries associated with the list. See Obtaining List Monitoring Information for additional information about list monitoring information entries. This field is initialized to the model-dependent maximum number of connectors to the structure.
• For structures allocated in a CFLEVEL=0 coupling facility, the value of the list cursor (entry ID to which it points or zero). This field is initialized to zero when the structure is allocated.
