Table 20. Open Feedback Area (continued)
Offset Data Type Length Contents File Type
Bit 1: Multiple member processing
0 Only the member specified will be processed.
1 All members will be processed.
Bit 2: Join logical file
0 File is not a join logical file.
1 File is a join logical file.
Bit 3: Local or remote data (DDM files)
0 Data is stored on local system.
1 Data is stored on remote system.
Bit 4: Remote System/38 or AS/400 data (DDM files). Applicable only if the
value of Bit 3 is 1.
0 Data is on a remote System/38 or AS/400 system.
1 Data is not on a remote System/38 or AS/400 system.
Bit 5: Separate indicator area
0 Indicators are in the I/O buffer of the program.
1 Indicators are not in the I/O buffer of the program. The
DDS keyword, INDARA, was used when the file was
created.
Bit 6: User buffers
Bit 7: Reserved.
0 System creates I/O buffers for the program.
1 User program supplies I/O buffers.
Bit 8: Additional commitment lock level indicator. This is only valid if bit 3 of
the character at offset 115 is one.
If bit 4 of the character at offset 115 is zero:
0 Only changed records are locked (LCKLVL(*CHG)).
1 All records accessed are locked, but the locks are released
when the current position in the file changes
(LCKLVL(*CS)).
If bit 4 of the character at offset 115 is one:
0 All records accessed are locked (LCKLVL(*ALL)).
1 Reserved.
133 Character 2 Open identifier. This value is unique for a full open operation (SHARE(*NO)) or
the first open of a file that is opened with SHARE(*YES). This is used for display
and ICF files, but is set up for all file types. It allows you to match this file to an
entry on the associated data queue.
135 Binary 2 The field value is the maximum record format length, including both data and
file-specific information such as: first-character forms control, option indicators,
response indicators, source sequence numbers, and program-to-system data. If the
value is zero, then use the field at offset 44.
