The grouping variables are given by the GROUPING parameter:
         GROUPING=<gr.vble1>,<gr.vble2>, ...
For each grouping variable the grouping structure may be given in the
form
         <gr.vble>=value1(label1),value2(label2), ...
The labels given in parenthesis are optional. If the grouping values
are given in ascending order then they are considered as cutpoints
for forming groups, e.g.
          KNOWLDGE=20,50,80,110,140
Values greater than the last cutpoint are treated as missing values.
The list above could be shortened by the notation 20(30)140.

You can use string variables as grouping variables. The grouping
structure of a string variable is given in the form
          <gr.vble>=symbol1,symbol2, ...
Note that only the first 8 characters of a string variable are
significant.

If the grouping structure of a grouping variable is not given then
the all existing values of that variable are used.

Theoretically at most 6 grouping variables may be given. The maximum
number of groups for each grouping variable is 32 (can be altered by
the parameter setting MAXNCL=<new limit>). In practice these values
are considerably limited by the space available. The space requirement
is appr. proportional to the product of the number of classes.
