The XEXPORT transformation writes the active dataset dictionary and
data to a specified portable file.
This transformation is a PSPP extension.
It is similar to the EXPORT procedure, with two differences:
XEXPORT is a transformation, not a procedure.  It is executed when
the data is read by a procedure or procedure-like command.
XEXPORT does not support the UNSELECTED subcommand.
See EXPORT, for more information.
