For format 8 indexed files, the FILEPOINTERSIZE parameter specifies the length in bytes to use to store file pointers.
FILEPOINTERSIZE={6|8}
6 | Use 6 bytes, allowing for files up to 256 terabytes. |
8 | Use 8 bytes, allowing for files over 256 terabytes. |
Default: | 6 |
The FILEPOINTERSIZE=8 option uses up more space to store file pointers. Therefore, the resulting file size might increase slightly.
