+       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.

+
+       * list.q Changed from using fixed length char buffers to struct 
+       string so that any length variables can be used.

+
+       Further clean up the CMD_* command result codes.
+       
+       * (enum cmd_result_extensions) New.  Add CMD_END_INPUT_PROGRAM and
+       CMD_END_CASE result codes.
+       (struct input_program_pgm) Added case_nr, write_case, wc_data
+       members for use by END CASE transformation.
+       (emit_END_CASE) New function.
+       (cmd_input_program) Interpret CMD_END_CASE by outputting an END
+       CASE transformation.  If none is output by the input program
+       itself, add one automatically at the end.  Change lack of
+       variables from warning to error.
+       (cmd_end_input_program) Return CMD_END_INPUT_PROGRAM instead of
+       CMD_END_SUBLOOP.
+       (input_program_source_read) No longer any need to special-case END
+       CASE.  Handle TRNS_DROP_CASE properly.  Initialize new members in
+       inp for use by END CASE transformation.
+       (destroy_input_program) New function.
+       (input_program_source_destroy) Just call destroy_input_program().
+       (cmd_end_case) Just return CMD_END_CASE.
+       (end_case_trns_proc) No longer a stub handled by
+       input_program_source_read().  Actually output the case and
+       increment the case number.

+       Remove vestiges of REPEATING DATA support.

+       * automake.mk (src_language_data_io_libdata_io_a_SOURCES): Removed
