When the system returns control to your problem program, the low-order byte of register 15 contains a return code. If register 15 is nonzero, the low-order byte of register 0 contains a reason code.
The SYNCDEV return and reason codes are:
| Return Code (15) | Reason Code (0) | Meaning |
|---|---|---|
| 00 (X'00') | Successful completion. Register 0 always contains 0. | |
| 04 (X'04') | 01 (X'01') | Incorrect parameter. |
| 04 (X'04') | 02 (X'02') | Incorrect DCB or a DEB error. |
| 03 (X'03') | System error occurred. | |
| 04 (X'04') | Possible system error. | |
| 05 (X'05') | 1) Device does not support buffering, or 2) SYNCDEV was issued for a DASD data set that is not supported. | |
| 06 (X'06') | Device does not support block IDs for tape data. | |
| 07 (X'07') | Invalid environment was detected by an SMS service while processing a DASD data set. Probable system error. | |
| 08 (X'08') | This is an informational message that is issued when using QSAM to process a DASD data set. SYNCDEV completed successfully. Logical records left in your QSAM buffer might not have been written to DASD. | |
| 11 (X'0B') | Unsuccessful call to ESTAE macro. | |
| 12 (X'0C') | Insufficient virtual storage available. | |
| 08 (X'08') | 00 (X'00') | Permanent I/O error during read block ID or synchronize command. |
| 12 (X'0C') | 00 (X'00') | Permanent I/O error on the last channel
program with loss of data (for tape data only).
Note: If you specified a SYNAD option in the DCB or DCBE and issue
a PUT or CHECK macro after this error occurs, the system does not
call the SYNAD routine unless an I/O error recurs.
|
| 01 (X'01') | An I/O error was detected by a previous output request while processing a DASD data set. |
