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 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 64-byte string of the internal key token containing the data translation (DATAXLAT) key, or the label of the CKDS record containing the DATAXLAT key used to encipher the input string.

The 64-byte string of an internal key token containing the DATAXLAT key, or the label of the CKDS record containing the DATAXLAT key, used to reencipher the encrypted text.

The length of the ciphertext that is to be processed. The text length must be a multiple of 8 bytes. The maximum length of text is 2,147,836,647 bytes.

The text that is to be translated. The text is enciphered under the data translation key specified in the key_identifier_in parameter.

The 8-byte initialization vector that is used to decipher the input data. This parameter is the initialization vector used at the previous cryptographic node.

The 8-byte initialization vector that is used to encipher the input data. This is the new initialization vector used when the callable service enciphers the plaintext.

The field where the callable service returns the translated text.

For CSNBCTT1 only, the ALET of the text to be translated.

For CSNBCTT1 only, the ALET of the text_out field that the application supplies.
