+group are presented together in a single table. With
+@subcmd{SEPARATE}, each analysis is presented in a separate table.
+Not all procedures honor the distinction.
Groups are formed only by @emph{adjacent} cases. To create a split
using a variable where like values are not adjacent in the working file,
-you should first sort the data by that variable (@pxref{SORT CASES}).
+first sort the data by that variable (@pxref{SORT CASES}).
Specify @subcmd{OFF} to disable @cmd{SPLIT FILE} and resume analysis of the
