Understanding the MOVE Operations

z/OS MVS Programming: Sysplex Services Guide
SA23-1400-00

There are four types of move operations:
  • DATAOPER=NONE

    Move a list entry.

  • DATAOPER=READ

    Move a list entry and read data from it.

  • DATAOPER=WRITE with ENTRYTYPE=OLD

    Move a list entry and write data to it.

  • DATAOPER=WRITE with ENTRYTYPE=ANY

    Move a list entry and write data to it. If no existing list entry meets the specified selection criteria, create a new list entry at the target list position.

Note: List entries can be moved only within the same list structure.

Guide to the Topic

MOVE: Moving a List Entry is divided into five topics:

  1. The first topic provides information about input parameters applicable to all MOVE requests.
  2. The second topic, Moving a List Entry Without Performing a Read or Write Operation, describes how to perform a MOVE request without a read or write operation.
  3. The third topic, Performing a Write Operation as part of a MOVE Request, describes how to perform a write operation as part of a MOVE request.
  4. The fourth topic, Performing a Read Operation as Part of a Move Request, describes how to perform a read operation as part of a MOVE request.
  5. The fifth topic, Receiving Answer Area Information from a MOVE Request, lists the answer area information returned from all MOVE requests.
A Note about Terminology:
  • The source list is the list containing the target list entry before the list service performs the MOVE operation. The list that is searched for the target list entry before creating a new one, is also considered the source list.
  • The target list is the list that receives the moved list entry or the newly created one. A single list can be both the source and target list, as is the case when a list entry is created as part of a MOVE request.
  • The target list entry is the list entry to be moved or created.
