Description
The file status
Valid settings of FIFLAGS are (options can be summed):
| Setting | Meaning |
|---|---|
| X'80' | Group index entry required (sorted files). Turned off if not a sorted file. Only turned on when sorted file is populated. |
| X'40' | Table B appends page full. Turned on when file is initially created (see "Default value" above), then turned off when a record is stored in Table B. Turned back on if Table B fills up. |
| X'10' | Field-level constraints. At least one field with a constraint (UNIQUE or AT-MOST-ONE) exists in the file. Always on if true. |
| X'08' | New Table C logic for initial property entry. Always on if file is post-Release 9.0. |
| X'04' | Ordered Index list page full. Turned off when Table D is populated. |
| X'02' | Current hash index list page full. Always on. |
| X'01' | File is post-Release 3.16. Probably always on. |
