Controlling subset pointer retention when changing the DEDB structure
Use the SUBSET_POINTERS keyword to retain the subset pointer settings when you change the DEDB structure.
Note
SUBSET_POINTERS is a required keyword when using the CHANGE command.
If subset pointer settings are defined in the DEDB, you can specify one of the following values for the SUBSET_POINTERS keyword:
| Value | Description |
|---|---|
| NO | (Default) Clears all subset pointers in output areas and does not transfer subset pointers from input areas to output areas |
| YES | Transfers subset pointers from input areas to output areas The actual pointer value (RBA) is translated to refer to the location of the segment after it has been transferred to an output area. |
The following figure shows an example of the SUBSET_POINTERS keyword with the CHANGE command:
CHANGE DBD=<dbdName>,SUBSET_POINTERS=YES
