Reason code (server errors)

If a server failure occurs in the SMSVSAM address space for VSAM RLS or DFSMStvs, the return code in register 15 indicates a server error (16). The RPL feedback area contains a reason code identifying the type of server failure. Table 1 lists the reason codes that can be in the feedback area and explains the associated failures.
