by value in-length
by value in-encoding

- Picture: pic x(4) comp-5
- out-string
- Picture: pic x(n)
- out-length
- Picture: pic x(4) comp-x
- out-encoding
- Picture: pic x(4) comp-5
- flags
- Picture: pic x(4) comp-5
- reserved
- Picture: pic x(4) comp-x
- status-code

On Entry:
- in-string
- The source string to convert.
- in-length
- The length of the source string.
- in-encoding
- The encoding type of the source string. Must be one of:
Value
|
Encoding
|
0
|
UTF-8
|
1
|
UTF-16 (native)
|
2
|
UTF-16 (portable)
|
3
|
ASCII/MBCS characters (current locale)
|
4
|
EBCDIC character (CHARSET"EBCDIC" encoding)
|
5
|
ASCII/MBCS characters (current locale)
|
- out-length
- Maximum buffer length available for the converted string.
- If the value is zero on entry, the call returns the size of the buffer required for the conversion only, and does not perform the actual conversion.
- out-encoding
- The encoding type of the converted string. Must be one of:
Value
|
Encoding
|
0
|
UTF-8
|
1
|
UTF-16 (native)
|
2
|
UTF-16 (portable)
|
3
|
ASCII/MBCS characters (current locale)
|
4
|
EBCDIC character (CHARSET"EBCDIC" encoding)
|
5
|
ASCII/MBCS characters (current locale)
|
- flags
- Reserved - must be set to zero.
- reserved
- Must be set to zero.
On Exit:
- out-string
- The converted string. If
out-string is not large enough to contain the converted data, an error occurs.
- If any character in
in-string does not have an equivalent character in the output encoding, then it will be converted to a system dependent replacement character
Note: This should only possibly occur when converting from a UTF encoding to an ASCII or EBCDIC character.
- out-length
- The actual buffer length of
out-string (the converted string).
- status-code
- The result of the conversion. Will be one of:
Value
|
Result
|
0
|
success
|
1
|
target buffer too small
|
2
|
out of memory
|
3
|
unsupported conversion
