Description

A WRITE_LCONTROLS request allows you to modify the list controls for the list specified by LISTNUM. Any one or more of the following list attributes can be changed:

The list authority (NEWAUTH).
The list limit (LISTLIMIT) that defines the number of elements or entries allowed on the list.
The list description (LISTDESC) that you define for the list.

With a coupling facility of CFLEVEL=1 or higher, you can also modify the following additional list controls for the list specified by LISTNUM.

The list key (LISTKEY) and the maximum value for the list key associated with the list (MAXLISTKEY).
The list cursor and the direction in which processing with the cursor is to occur (SETCURSOR). The direction you specify applies only when a request to update the list cursor specifies CURSORUPDTYPE=NEXTCOND.

An authority comparison is required for all WRITE_LCONTROLS requests. If you do not specify AUTHCOMP, the system uses a default value of binary zeros for the authority comparison.
