In a two way table, column variable values will be truncated when you
use a format with width of 8 or less for a variable whose name is longer
than 8 characters.

To avoid the problem, if you use a format for the column variable in a 2
way PROC FREQ where that variable's name is more than 8 characters, make
sure the format width is greater than 8 characters.

The following sample program demonstrates the problem and its
circumvention when run with the respective FORMAT statements.

   data test;
     input id long_var_name;
   cards;
   1 1234
   2 2345
   3 3456
   run;

   proc freq data=test;
     tables id*long_var_name;

      ** format of 8 or less causes problem    **;
      format long_var_name 4.;

      ** use this format to circumvent problem **;
      format long_var_name 9.;
   run;

This problem has been fixed in V8.2.
