Other features

FORMAT procedure

FORMAT statement

Data set:

CAKE

This example

computes the statistics for the specified keywords and displays them in order
specifies the field width of the statistics
suppresses the column with the total number of observations
analyzes the data for the one-way combination of cake flavor and the two-way combination of cake flavor and participant's age
assigns user-defined formats to the class variables
uses multilabel formats as the levels of class variables
orders the levels of the cake flavors by the descending frequency count and orders the levels of age by the ascending formatted values.
