When the request is completed, register 15 indicates the status of the request. A reason code of 0 indicates successful completion. Table 1 lists nonzero reason codes and their meanings.
| Reason Code (RPLERRCD) When Register 15=0(X'0') | Meaning |
|---|---|
| 0(X'0') | Request completed successfully. |
| 4(X'4') | Request completed successfully. For retrieval, VSAM mounted another volume to locate the record. For storage, VSAM allocated additional space or mounted another volume. |
| 8(X'8') | For GET requests, indicates a duplicate alternate key exists (applies only when accessing a data set using an alternate index that allows non-unique keys). For PUT requests, indicates that a duplicate key was created in an alternate index with the non-unique attribute. |
| 12(X'C') | All buffers, except for the buffer just obtained, may have been modified and may need to be written. It is suggested you issue the WRTBFR macro. |
| 16(X'10') | The sequence-set record does not have enough space to allow it to address all the control intervals in the control area that should contain the record. The record was written into a new control area. |
| 20(X'14') | Mass Storage System macros CNVTAD, MNTACQ, and ACQRANGE are no longer supported. |
| 24(X'18') | Buffer found but not modified; no buffer writes performed. |
| 28(X'1C') | Control interval split indicator was detected during an addressed GET NUP request. |
| 32(X'20') | Request deferred for a resource held
by the terminated RPL is asynchronous and cannot be restarted. A MRKBFR request is invalid because no candidate buffers can be found. For RLS, there are no locks to retain since no update locks exist for this CICS® address space, CICS transaction, or SPHERE. |
| 36(X'24') | Possible data set error condition was detected. |
| 40(X'28') | Possible data set error condition was detected. |
| 42(X'2A') | SMFIOCNT to generate SMF type 30 records failed. |
| 43(X'2B') | EOV called to retrieve or update the dictionary token in the extended format cell. |
| 44(X'2C') | EOV called to update catalog statistics. |
| 48(X'30') | An error occurred during CA Reclaim. The erase was successful. |
 52(X'34') |
CA reclaim failed due to subtask in key 9. ERASE
was successful. |
| 56(X'38') |
CA reclaim failed due to no storage. ERASE was
successful. |
| 60(X'3C') |
CA reclaim failed due to CI #2 not on 2nd level.
ERASE was successful. |
| 64(X'40') |
CA reclaim failed due to reclaiming high key
entry. ERASE was successful. |
| 68(X'44') |
For NSR or LSR, not enough buffers were available
so VSAM has successfully added additional buffers to complete the
request. The request was successful. |
