+       Continue reforming procedure execution.  In this phase, get rid of
+       many global variables, consolidating procedure execution in
+       procedure.c.  Encapsulate transformations in new "struct
+       trns_chain".  Also, change implementation of N OF CASES, FILTER,
+       and PROCESS IF from special cases to transformations.
+        
+       * aggregate.c (cmd_aggregate) Use discard_variables().

+       variables used in the model to (*model->pred)().
