A DELETE request allows you to delete a single list entry from the list structure. Once removed from the list, the storage resources associated with the entry can be reused. You can also specify that the designated entry be deleted only if it contains data that satisfies a version number comparison. The entry you designate must exist on the list you specify, or the request fails with no change to the structure. With a coupling facility of CFLEVEL=1 or higher, the following
additional functions are supported for a DELETE request:
On the DELETE request, you can optionally read data from the entry
by specifying DATAOPER=READ. Before it deletes the entry, the system
reads any combination of the following types of data for the designated
entry:
Whether a particular data type is returned also depends on whether
the local storage area to contain that data is specified. Listed below
is the data that is returned and the storage area that should be specified
to contain that returned data:
Additionally, you can perform locking functions with a DELETE request by specifying LOCKINDEX. The lock entry designated by LOCKINDEX will be operated on as specified by LOCKOPER. |
