When you copy DBCS files to alphanumeric files, the system sends you an<br />
informational message describing the difference in file types.<br />
Either the FMTOPT(*MAP) or FMTOPT(*NOCHK) option of the copy file function<br />
must be specified for copies from a physical or logical file to a physical file when<br />
there are fields with the same name in the from-file and to-file, but the data type<br />
for fields is as shown in the following table.<br />
From-<strong>File</strong> Field Data Type To-<strong>File</strong> Field Data Type<br />
A (character) J (DBCS-only)<br />
O (DBCS-open) J (DBCS-only)<br />
O (DBCS-open) E (DBCS-either)<br />
E (DBCS-either) J (DBCS-only)<br />
J (DBCS-only) G (DBCS-graphic)<br />
O (DBCS-open) G (DBCS-graphic)<br />
E (DBCS-either) G (DBCS-graphic)<br />
G (DBCS-graphic) J (DBCS-only)<br />
G (DBCS-graphic) O (DBCS-open)<br />
G (DBCS-graphic) E (DBCS-either)<br />
G (UCS-2 graphic) A (Character (CCSID non-65535))<br />
G (UCS-2 graphic) J (DBCS-open (CCSID non-65535))<br />
G (UCS-2 graphic) E (DBCS-either (CCSID non-65535))<br />
G (UCS-2 graphic) J (DBCS-only (CCSID non-65535))<br />
G (UCS-2 graphic) G (DBCS-graphic)<br />
A (Character (CCSID non-65535)) G (UCS-2 graphic)<br />
O (DBCS-open (CCSID non-65535)) G (UCS-2 graphic)<br />
E (DBCS-either (CCSID non-65535)) G (UCS-2 graphic)<br />
J (DBCS-only (CCSID non-65535)) G (UCS-2 graphic)<br />
G (DBCS-graphic) G (UCS-2 graphic)<br />
When you use FMTOPT(*MAP) on the CPYF command to copy data to a<br />
DBCS-only field or DBCS-graphic field, the corresponding field in the from-file<br />
must not be:<br />
v Less than a 2-byte character field<br />
v An odd-byte-length character field<br />
v An odd-byte-length DBCS-open field<br />
Note: DBCS-graphic is the only type allowed to be CCSID 65535 when using<br />
FMTOPT(*MAP) copying from or to a UCS-2 graphic field. UCS-2 graphic<br />
cannot be CCSID 65535.<br />
If you attempt to copy with one of these specified in the from-field, an error<br />
message is sent.<br />
When you copy double-byte data from one database file to another with the<br />
FMTOPT(*MAP) parameter specified, double-byte data will be copied correctly.<br />
The system will perform correct padding and truncation of double-byte data to<br />
ensure data integrity.<br />
When using the CPYF command with FMTOPT(*MAP) to copy a DBCS-open field<br />
to a graphic field, a conversion error occurs if the DBCS-open field contains any<br />
SBCS data (including blanks).
