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 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 data that is passed to the installation exit.

The number of keywords you supplied in the rule_array parameter. Value must be 1.

The smartcard format rule for the callable service. A keyword that provides control information to the callable service. See Table 238 for a list. A keyword is left-justified in an 8-byte field and padded on the right with blanks.

Length in bytes of the source_key_identifier variable. The maximum length is 3500 bytes.

This field contains either a key label identifying an RSA private key or an external public-private key token. The private key must be wrapped with a key encrypting key.

Length in bytes of the source_transport_key_identifier parameter. This value must be 64.

This field contains an internal token or label of a DES key-encrypting key. This key is used to unwrap the input RSA key token specified with parameter source_key_identifier. See Usage Notes for details on the type of transport key that can be used

Length in bytes of the target_transport_key_identifier parameter. This value must be 64.

This field contains an internal token or label of a DES key-encrypting key. This key is used to wrap the output RSA key returned with parameter target_key_token. See Usage Notes for details on the type of transport key that can be used.

Length in bytes of the target_key_token parameter. On output, the value in this variable is updated to contain the actual length of the target_key_token produced by the callable service. The maximum length is 3500 bytes.

This field contains the RSA key in the smartcard format specified in the rule array and is protected by the key-encrypting key specified in the target_transport_key parameter. This is not a CCA token, and cannot be stored in the PKDS.
