Hi Randy,

Is it really necessary to create a variable Class? Tell us for what purpose
you need it and the answer might be that you may instead use statements like:
   CLASS ID_Group ID;
or
   BY ID_Group ID;
depending on your goal and PROC used, without using a deduced class variable.

Regards - Jim.
