The BY statement specifies the variable or variables by
which data is grouped for processing. A separate grid is produced for each
value of the BY variable. The BY statement is optional.
- DESCENDING
- indicates that the input data set is sorted
in descending order. This is the default.
- NOTSORTED
- indicates that observations with the same
BY variable values are to be grouped as they are encountered, without regard
for whether the values are in numerical
order.
