Response-buffer-length is a four-byte field that specifies the desired length of the buffer in which responses received from the database are made available to the application.

The value of zero indicates that DBCHCL is to use the default value from the HSHSPB bytes for the Response-buffer-length.
The application may change the value in Response-buffer-length. The minimum value is 256.
The maximum value is approximately. . . | If Maximum-parcel is set to... |
---|---|
32767 | O |
65535 | H |
2,147,483,639 | H, and the database supports ExtendedRespond, as indicated by the DBCHQE Extended-response-support query. |
The actual maximum may vary slightly with the version of the database being used; the value may be obtained using the DBCHQE CLIv2-limits query.
If Two-response-buffers in the DBCAREA is set to 'Y', each response buffer is the specified size.
