+@cmd{OUTPUT} changes the appearance of the tables in which results are printed.
+In particular, it can be used to set the format and precision to which results are displayed.
+
+After running this command, the default table appearance parameters will have been modified and each
+new output table generated will use the new parameters.
+
+Following @code{/TABLECELLS SELECT =} a list of cell classes must appear, enclosed in square
+brackets. This list determines the classes of values should be selected for modification.
+Each class can be:
+
+@table @asis
+@item SIGNIFICANCE
+Significance of tests (p-values).
+
+@item COUNT
+Counts or sums of weights.
+@end table
+
+The value of @var{fmt_spec} must be a valid output format (@pxref{Input and Output Formats}).
+Note that not all possible formats are meaningful for all classes.
