+ multipass_procedure().
+
+Wed May 3 23:06:43 2006 Ben Pfaff <blp@gnu.org>
+
+ 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.
+
+ * sort.c: (prepare_to_sort_active_file) Don't run a procedure
+ here.
+ (sort_active_file_in_place) Rewrite to run a procedure, capture
+ the output, sort the output, and set that as the source for the
+ next procedure.
+ (struct sort_to_casefile_cb_data) New structure.
+ (sort_to_casefile_callback) New function.
+ (sort_active_file_to_casefile) Rewrite to use
