Use the Clear PIN generate callable service to generate a clear PIN, a PIN validation value (PVV), or an offset according to an algorithm. You supply the algorithm or process rule using the rule_array parameter.

• IBM 3624 (IBM-PIN or IBM-PINO)
• IBM German Bank Pool (GBP-PINO) - not supported on an IBM zSeries 990 and subsequent releases.
• VISA PIN validation value (VISA-PVV)
• Interbank PIN (INBK-PIN)

The callable service can execute only when ICSF is in special secure mode. This mode is described in Special Secure Mode.

For guidance information about VISA, see their appropriate publications. The Interbank PIN algorithm is available only on S/390 Enterprise Servers, the S/390 Multiprise, and the IBM Zseries.

The callable service name for AMODE(64) invocation is CSNEPGN.
