| CLASS Statement |
The CLASS statement names the classification variables that are used to group (classify) data in the analysis. Classification variables can be either character or numeric.
Class levels are determined from the formatted values of the CLASS variables. Thus, you can use formats to group values into levels. See the discussion of the FORMAT procedure in the SAS Language Reference: Dictionary for details. The CLASS statement must precede the MODEL statement.
