Description

The file status

Valid settings of FIFLAGS are (options can be summed):

SettingMeaning
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.
