Double-byte data that is already in a supported DBCS code page, such as IBM-939, does not need to be converted.

Rule: DBCS data not in code page IBM-939 must be converted to IBM-939 with the iconv command so that it can be processed in the z/OS UNIX environment.

Guideline: If the data is in a code page not supported by the shell, you can copy the data with the OCOPY command first and then convert it using the iconv command. Or you can convert the data with the TSO/E ICONV CLIST and then copy it using the OCOPY command.
