Table 2. Return and reason codes from z/OS Unicode Services
Hexadecimal Return Code Hexadecimal Reason Code Name of reason code Meaning and Action Component
0 0 Name: CUN_RS_OK

Meaning: The operation was successful.

Action: None.

All
4 1 Name: CUN_RS_TRG_EXH

Meaning: The target buffer was exhausted before all characters in the source buffer were converted.

Action: Call the service again with either a target buffer large enough to hold the complete result of the conversion or keep the result of the conversion just performed and repeat calling the service with the part of the source buffer that was not converted and concatenate the results of the various conversions.

Conversion
4 2 Name: CUN_RS_INV_HANDLE_NOSET

Meaning: Conversion is terminated. The handle is invalid because a SET UNI command has changed the environment.

Action: Clear the handle and make sure that the FROM-CCSID and TO-CCSID are specified in the parameter area. Then call the service again.

Conversion
4 3 Name: CUN_RS_INV_HANDLE_SET

Meaning: Conversion is terminated. The handle is invalid because a SET UNI command is in process and will change the conversion environment.

Action: Clear the handle and make sure that the FROM-CCSID and TO-CCSID are specified in the parameter area. Consider waiting until the SET UNI command completes before calling the service again. Otherwise the same error condition is returned.

Conversion
4 4 Name: CUN_RS_NO_HANDLE

Meaning: Conversion is terminated. No handle can be obtained because a SET UNI command is in process and will change the conversion environment.

Action: Clear the handle and make sure that the FROM-CCSID and TO-CCSID are specified in the parameter area. Consider waiting until the SET UNI command completes before calling the service again. Otherwise the same error condition is returned.

Conversion
4 6 Name: CUN_RS_SUB_ACT_TERM

Meaning: A character was found in the source buffer which cannot be converted into a TO-CCSID character and the CUNBNPRM_Sub_Action flag specifies terminate with error.

Action:
  1. Check whether the input string is correct and whether the correct conversion tables are used.
  2. Turn on the Sub_Action flag to replace the invalid character with the target substitution character and call the conversion service again.
Conversion
4 7 Name: CUN_RS_MBC_INCOMPLETE

Meaning: An incomplete character was found in the source buffer. This error happens when not all bytes of a multi-byte character are found in the source buffer. For example, the incomplete character can be found at the end of the source buffer if only the first byte of a double-byte character fits into the buffer.

Action: Check whether the input string is correct. Make sure that the missing bytes are in the source string.

Conversion
4 8 Name: CUN_RS_CONTINUATION

Meaning: For character casing, the character condition of being FINAL or NON_FINAL in a word could not be determined, as the character was the last character in the source buffer but not the last character in the caller's source data. The character in question is not cased.

Action: Next call to casing service needs to start with the uncased character of this call as the first source character.

Case
4 9 Name: CUN_RS_STAGE2_FAIL

Meaning: An indirect character conversion, which first converts from the source CCSID into UCS-2 characters in a workarea and then in a second stage from the workarea to the target buffer, experienced an error during stage 2 conversion. As there is no correlation of the failing stage 2 character to a certain stage 1 character, we reset the source and target pointers and length values to the original caller's values. The workarea pointer and length values are updated to point to the character which failed conversion.

Action: Check whether the input string and the parameter settings used are reasonable.

Conversion
4 0A Name: CUN_RS_WRK_EXH

Meaning: The work buffer was exhausted before all characters in the target buffer could be processed.

Action: Call the service again with the new parameter value in the work buffer, where the work buffer size must be at least the same size as the target buffer.

Normalization
4 0B Name: CUN_RS_SOURCE_LEN_ZERO

Meaning: For collation, one or both of the source input parameters or both (CUNBOPRM_Src1_Buf_Len or CUNBOPRM_Src2_Buf_Len) has length zero. This is a completely valid operation when a comparison is needed. When a sort key needs to be generated, users will not be notified about zero lengths.

Action: Avoid the call to collation if one of the source input parameters has length zero (if CUNBOPRM_SKey_Opt=OFF). Performance will be improved. Results will be the same.

Collation
4 0C Name: CUN_RS_MAL_CHAR_ACT_TERM

Meaning: A character was found in the source buffer which is not a valid source character and could not be converted. CUNBCPRM_Mal_Action specifies “terminate with error”.

Action: Check whether the input string is correct and the correct conversion tables were used. An incomplete character may be causing a range check to fail.

Conversion
4 0D Name: CUN_RS_INVALID_COLL_DATA_VER

Meaning: The specified Collation version is already loaded into the Unicode DataSpace.

Action: Check whether the specified collation version is correct and recall the service.

Collation
4 0E Name: CUN_RS_INVALID_ALTERNATE_VALUE

Meaning: Invalid alternate value. When Collation API version is set to CUNBOPRM_Ver2 or CUN4BOPR_Ver2 (31 and 64 bit respectively) there are only two valid values. If the invalid value is entered, this RS is set and the default value is set.

Action: Call the service again with a valid alternate value:
  • ALTERNATE_NON_IGNORABLE
  • ALTERNATE_SHIFTED
Collation
4 0F Name: CUN_RS_INVALID_NORMALIZATION_VALUE

Meaning: Invalid normalization value. When Collation API version is set to CUNBOPRM_Ver2 or CUN4BOPR_Ver2 (31 and 64 bit respectively), there are only two valid values. If invalid value is entered, this RS is set and default is value is set.

Action: Call the service again with a valid normalization value:
  • NORMALIZATION_OFF
  • NORMALIZATION_ON
Collation
4 10 Name: CUN_RS_LOCALES_AND_UCR_ARE_EXCLUSIVE

Meaning: CUNBOPRM_Locale/CUN4BOPR_Locale (31-bit and 64-bit respectively) and CUNBOPRM_Collation_Rules_File/ CUN4BOPR_Collation_Rules_File (31-bit and 64-bit respectively) are mutually exclusive. If this were the case then this RS is set and Locale info has the highest priority over User Collation Rules sets.

Action: Call the service again with CUNBOPRM_Locales/CUN4BPRM_Locales (31-bit and 64-bit respectively) information or CUNBOPRM_Collation_Rules_File/ CUN4BOPR_Collation_Rules_File Collation (31-bit and 64-bit respectively) rules information but not both.

Collation
