The `XSAVE` transformation writes the active dataset’s dictionary and data to a system file. It is similar to the `SAVE` procedure, with two differences:

- `XSAVE` is a transformation, not a procedure. It is executed when the data is read by a procedure or procedure-like command.
- `XSAVE` does not support the `UNSELECTED` subcommand.

See SAVE, for more information.
