Interpreting output from save (SAV) and restore (RST)

 

When you use the Save (SAV) command or the Restore (RST) command, you can direct output to a stream file or to a user space.

If data already exists in the stream file or user space that you specify, the command writes over that data. It does not append the new data to any existing data.

To specify a stream file, have *W authority to the stream file and *R authority to the directory for the stream file.

To specify a user space, have *CHANGE authority to the user space and *USE authority to the library. The server needs an *EXCLRD lock on the user space.
