The return code specifies the general result of the callable service. Appendix A. ICSF and TSS Return and Reason Codes lists the return codes.

The reason code specifies the result of the callable service that is returned to the application program. Each return code has different reason codes that are assigned to it that indicate specific processing problems. Appendix A. ICSF and TSS Return and Reason Codes lists the reason codes.

The length of the data that is passed to the installation exit. The length can be from X'00000000' to X'7FFFFFFF' (2 gigabytes). The data is identified in the exit_data parameter.

The number of keywords you supplied in the rule_array parameter. Currently no rule_array keywords are defined; thus, this field must be set to 0.

Currently, no rule_array keywords are defined for this service. You must still specify this parameter for possible future use.

A 16-byte string that contains the origin identifier that is defined in the ANSI X9.17 standard. The string must be ASCII characters, left-justified, and padded on the right by space characters. The string must be a minimum of four non-space characters.

A 16-byte string that contains the destination identifier that is defined in the ANSI X9.17 standard. The string must be ASCII characters, left-justified, and padded on the right by space characters. The string must be a minimum of four non-space characters.

A 64-byte area that contains either an internal token, or a label of an internal token for an AKEK that permits notarization.

A 64-byte area where the internal token of a partially notarized AKEK will be returned. This AKEK cannot be used directly as a notarizing KEK until the notarization process has been completed. To do this, specify CPLT-NOT as the rule_array keyword in any service in which you intend to use this key as a notarizing KEK.
