+Sat May  6 14:25:49 2006  Ben Pfaff  <blp@gnu.org>
+
+	* sys-file-writer.c: (does_dict_need_translation) Fix bug:
+	inverted return value (!).
+
+Sat May  6 13:37:52 2006  Ben Pfaff  <blp@gnu.org>
+
+	Continue reforming procedure execution.  
+
+	* procedure.c: Search and replace "vfm" by "proc".  Notably:
+	(static var vfm_source) Rename proc_source.  Update all
+	references.
+	(static var vfm_sink) Rename proc_sink.  Update all references.
+	
+Sat May  6 12:38:55 2006  Ben Pfaff  <blp@gnu.org>
+
+	Continue reforming procedure execution.  In this phase, remove
+	PROCESS IF, which was deprecated anyway and can be easily
+	simulated with TEMPORARY followed by SELECT IF.
+
+	* procedure.c: (open_active_file) Don't call
+	add_process_if_trns().
+	(discard_variables) Get rid of redundant call to
+	proc_cancel_all_transformations().
+	(add_process_if_trns) Removed.
+	(process_if_trns_proc) Removed.
+	(process_if_trns_free) Removed.
+
+Sat May  6 10:58:05 2006  Ben Pfaff  <blp@gnu.org>
+
+	Continue reforming procedure execution.  In this phase, add
+	`const' to the case passed to procedure()'s callback.
+
+	Updated all users of procedure() as well.
+	
+	* procedure.c: (struct write_case_data) Add "const" to ccase
+	parameter for case_func member.
+	(procedure) Add "const" to ccase parameter for proc_func
+	parameter.
+	(multipass_case_func) Make ccase parameter const.
+	(internal_procedure) Add "const" to ccase parameter for case_func
+	parameter.
+	(split_procedure_case_func) Make ccase parameter const.
+	(multipass_split_case_func) Make ccase parameter const.
+	
+Sat May  6 10:30:33 2006  Ben Pfaff  <blp@gnu.org>
+
+	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.
+
+	Updated many users of procedure_with_splits() and
+	multipass_procedure_with_splits() to call
+	output_split_file_values() and to deal with increased use of
+	const.
+
+	* procedure.c: (struct split_aux_data) Add "const struct ccase *"
+	parameter to begin_func member.
+	(procedure_with_splits) Add "const struct ccase *" parameter to
+	begin_func parameter.  Make ccase parameter const in proc_func
+	parameter.
+	(split_procedure_case_func) Don't dump split file group.  Pass
+	case to begin_func.
+	(dump_splits) Moved to language/dictionary/split-file.c as
+	output_split_file_values().
+	(struct multipass_split_aux_data) Add "const struct ccase *"
+	parameter to split_func member.
+	(multipass_procedure_with_splits) Add "const struct ccase *"
+	parameter to split_func parameter.
+	(multipass_split_case_func) Save new SPLIT FILE case before
+	outputting case.
+	(multipass_split_output) Pass saved SPLIT FILE case to split_func.
+	
+Fri May  5 22:48:50 2006  Ben Pfaff  <blp@gnu.org>
+
+	Continue reforming procedure execution.  Change
+	internal_procedure() so that it calls open_active_file() and
+	close_active_file(), which isolates most of the actual procedure
+	functionality.
+
+	* procedure.c: (struct write_case_data) Rename `proc_func' member
+	to `case_func' and update all references.
+	(procedure) Rewrite as one-line wrapper around
+	internal_procedure().
+	(struct multipass_aux_data) New.
+	(multipass_callback) Renamed multipass_case_func().  Use struct
+	multipass_aux_data as auxiliary data.
+	(multipass_end_func) New function.
+	(multipass_procedure) Rewrite as wrapper for internal_procedure()
+	that uses multipass_case_func, multipass_end_func.
+	(internal_procedure) Add `end_func' argument.  Move optimization
+	of trivial case in here.  Move call to open_active_file() and
+	close_active_file() in here.  Now assert that vfm_source is
+	non-null.
+	(procedure_with_splits_callback) Rename
+	split_procedure_case_func().
+	(split_procedure_end_func) New function.
+	(multipass_split_callback) Rename multipass_split_case_func.
+	(multipass_split_end_func) New function.
+	(discard_variables) No need to test for nonnull vfm_source.
+

-	Get rid of unused member.
+	Continue reforming procedure execution.  Get rid of unused member.
 
 	* procedure.c: (struct write_case_data) Remove `cases_analyzed'
 	member.
