Required Argument

list

specifies one or more integers that define the number of class variables to combine to form all the unique combinations of class variables. For example, you can specify 2 for all possible pairs and 3 for all possible triples. The list can be specified in the following ways:

• m
• m1 m2 … mn
• m1,m2,…,mn
• m TO n <BY increment>
• m1,m2, TO m3 <BY increment>, m4

Range:0 to maximum number of class variables

See:WAYS option

Example:The following code is an example of creating two-way types for the classification variables A, B, and C. This WAYS statement is equivalent to specifying a*b, a*c, and b*c in the TYPES statement.

class A B C ; ways 2;
