+@subsection Example Split
+
+The file @file{horticulture.sav} contains data describing the @exvar{yield}
+of a number of horticultural specimens which have been subjected to
+various @exvar{treatment}s. If we wanted to investigate linear statistics
+of the @exvar{yeild}, one way to do this is using the @cmd{DESCRIPTIVES} (@pxref{DESCRIPTIVES}).
+However, it is reasonable to expect the mean to be different depending
+on the @exvar{treatment}. So we might want to perform three separate
+procedures --- one for each treatment.
+@footnote{There are other, possibly better, ways to achieve a similar result
+using the @cmd{MEANS} or @cmd{EXAMINE} commands.}
+@ref{split:ex} shows how this can be done automatically using
+the @cmd{SPLIT FILE} command.
+
+@float Example, split:ex
+@psppsyntax {split.sps}
+@caption {Running @cmd{DESCRIPTIVES} on each value of @exvar{treatment}}
+@end float
+
+In @ref{split:res} you can see that the table of descriptive statistics
+appears 3 times --- once for each value of @exvar{treatment}.
+In this example @samp{N}, the number of observations are identical in
+all splits. This is because that experiment was deliberately designed
+that way. However in general one can expect a different @samp{N} for each
+split.

+
+Unless @cmd{TEMPORARY} was used, after a split has been defined for
+a dataset it remains active until explicitly disabled.
