You can copy both spooled and nonspooled DBCS files.
Copy spooled DBCS files
Copy spooled files that have double-byte data by using the Copy Spooled File (CPYSPLF) command. However, the database file to which the file is being copied must have been created with the IGCDTA(*YES) value specified.
Copy nonspooled DBCS files
You can use the Copy File (CPYF) command to copy double-byte data from one file to another.
