+       Continue reforming procedure execution.  In this phase, get rid of
+       the output code for SPLIT FILE groups in procedure.c, which really
+       shouldn't be doing any output.  Move it into the individual
+       procedures instead.  This also adds some flexibility.
+
+       * list.q (write_all_headers): Call output_split_file_values().

+
+       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.
+        
+       * data-list.c: (data_list_trns_proc) Return TRNS_END_FILE at end
+       of file.  (Why didn't we do this before?)
+       (cmd_match_files) Direct procedure output to null sink.
+       Use discard_variables() instead of indirect version.
+
+       * inpt-pgm.c: Use transformation chain.
+       (struct input_program_pgm) Add trns_chain member.
+       (cmd_input_program) Initialize trns_chain member and capture
+       transformations with proc_capture_transformations().
+       (input_program_source_read) Use trns_chain_execute().
+       (destroy_input_program) Destroy input chain.
