To add a twin segment occurrence

  1. If browsing the database, click End Browse end browse.
  2. Using the IMS Database Editor toolbar, make DL/I calls to move your position in the database to where you want to add a twin.
  3. You can edit the data that is already there. Otherwise, initialize the segment, choosing a different segment layout if you want.
  4. Edit the key field to make it unique.
  5. Edit any other fields in which you want to modify or add data.
  6. When you have finished editing all the fields you want to change, click * to issue an ISRT DL/I call.

    Your current position in the database moves to the new segment occurrence.

Note:
  • If you have the Update warning option checked, click Yes to enable data updates. See To configure edit warnings for more information.
  • You cannot add a new segment occurrence while the Browse window is open.
  • Before clicking *, you can cancel the insert at any time by clicking Edit > IMS DB Editor > Undo Segment Edit.
