Explanation: The system detected an error while processing a Supervisor Call (SVC) instruction. The last 2 digits of this completion code, nn, are the operand of the SVC instruction in hexadecimal. For example, completion code X'F0D' means that the error occurred while the system was processing SVC X'0D', that is, SVC 13.
For recently installed SVCs, if the number (nn) is X'C8' thru X'FF', it is an installation defined SVC. If the SVC number is X'00' thru X'C7', and you continue to have a problem after following the next steps, contact the IBM Support Center.
