Specifies the number of ways to make unique combinations of class
variables.

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 
Example: 
To create the twoway
types for the classification variables A, B, and C, use

WAYS option 
The following code is an
example of creating twoway 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.
