Description
CBLDCDAM ('CLOS') closes logical files.
Data areas whose values are set in the UAP
data-name-A
Specify VALUE 'DCDAMSVC' for the interface code used with the DAM file.
data-name-C
Specify a logical file name with up to 8 characters. If the specified logical file name comprises less than 8 characters, pad the remaining portion with space.
data-name-E
Specify VALUE 'CLOS' for the request code indicating that the logical file is closed.
data-name-H
Specify the file descriptor returned when the logical file was opened.
data-name-Z
Specify 0.
Data area to which a value is returned from OpenTP1
data-name-B
A status code of 5 digits is returned.
Status codes
Status code | Explanation |
---|---|
00000 | The logical file was closed normally. |
01600 | CBLDCRPC('OPEN ') was not called. |
A DAM file opened outside the transaction range is closed within the transaction range. (This error is returned only when accessing a recoverable DAM file.) | |
'N' is specified for atomic_update in the user service definition. (This error is returned only when accessing a recoverable DAM file.) | |
CBLDCDAM('STRT') was not called. (This error is returned only when accessing an unrecoverable DAM file.) | |
The UAP is incorrectly linked as follows:
|
|
01603 | The specified file descriptor is not the one which was acquired by opening the file normally. |
The DAM file is not open. | |
01690 | The interface code (data-name-A) is invalid. |
01691 | The request code (data-name-E) is invalid. |
