To copy a data set into a file and use data definition names (ddnames) instead of a data set name and path name, use the OCOPY command.

1. If the data set and file are not yet allocated, allocate them and specify ddnames, using either the ALLOCATE command or the DD statement in JCL.
   The ALLOCATE command has these operands for allocating a z/OS UNIX file:

   PATH
   PATHDISP
   PATHMODE
   PATHOPTS

   They are explained in z/OS TSO/E Command Reference.
2. Enter the OCOPY command, making sure that the ddnames used match the ddnames that were specified when the data set and file were allocated.
3. You can use the CONVERT option for single-byte data, but not for double-byte data. See Double-byte data for information about code page conversion for double-byte data.
4. If you are moving the data set or partitioned data set member permanently to the file system: After the copy is completed, delete the original using the TSO/E DELETE command.
