+       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().
+

+
+       * regression.q (regression_trns_resid_proc): Pass only the
+       variables used in the model to (*model->residual)().
+
+       * regression.q (regression_trns_pred_proc): Pass only the
+       variables used in the model to (*model->pred)().
+
+2006-04-26  Jason Stover  <jhs@math.gcsu.edu>
+
+       * regression.q: Added support for multiple transformations.
+       
+       * regression.q (regression_trns_resid_proc): New function.
+
+       * regression.q (regression_trns_pred_proc): New function.
+
+       * regression.q (subcommand_save): Added support for saving
+       predicted values.
+
+       * regression.q (regression_trns_free): New function. 
+
+       * regression.q (reg_get_name): New function.
+
+       * regression.q (reg_save_var): New function.
+
+Tue Apr 25 13:18:56 2006  Ben Pfaff  <blp@gnu.org>
+
+       * rank.q (parse_rank_function): Use SE instead of ME for parse
+       errors.
+
+Tue Apr 25 13:16:28 2006  Ben Pfaff  <blp@gnu.org>
+
+       * flip.c (flip_sink_write): Use snprintf() to simplify a bit of
+       code.
+
+2006-04-21  Jason Stover  <jhs@math.gcsu.edu>
+
+       * regression.q (try_name): New function. (Partly copied from
+       try_name in descriptives.c.)
+
+       * regression.q (subcommand_save): Choose residual variable names
+       correctly. 
+
+2006-04-20  Jason Stover  <jhs@math.gcsu.edu>
+
+       * regression.q (cmd_regression): Moved call to subcommand_save()
+       outside multipass_procedure_with_splits().
+       
+       * regression.q (regression_trns_proc): Fixed value counter n_vals
+       before calling *model->residual().
+
+2006-04-19  Jason Stover  <jhs@math.gcsu.edu>
+
+       * regression.q (regression_trns_proc): Fixed the look-up of the
+       number of variables.
+
+2006-04-18  Jason Stover  <jhs@math.gcsu.edu>
+
+       * regression.q (regression_trns_proc): Look up the residual
+       variable in the linear regression cache.
+
+       * regression.q (subcommand_save): Set the residual variable in the
+       linear regression cache.
+
+2006-04-17  Jason Stover  <jason@wonko.gcsu.edu>
+
+       * regression.q (regression_trns_proc): Accept case_idx as an int
+       to match the definition of trns_proc_func.
+
+2006-04-17  Jason Stover  <jhs@math.gcsu.edu>
+
+       * regression.q (regression_trns_proc): New function.
+
+       * regression.q (subcommand_save): Create variable residuals and
+       add a transformation to assign values to them. Also free the
+       linreg_cache if the SAVE command was not called. Removed the
+       casereading loop. Placed actual computation of residuals in
+       regression_trns_proc.
+
+       * regression.q (run_regression): Moved call to free
+       pspp_linreg_cache to subcommand_save.

        * examine.q (output_examine): Add casts to fix warnings.
