+
+ Make it possible to pull cases from the active file with a
+ function call, instead of requiring indirection through a callback
+ function.
+
+ * case-source.h (struct case_source_class): Change ->read function
+ to return a single case, instead of calling a callback function
+ for each case. Change ->destroy function to return an error
+ status.
+
+ * case-source.c (free_case_source): Pass along the value returned
+ by the case_source ->destroy function.
+
+ * procedure.c (struct write_case_data): Removed.
+ (struct dataset): Added some members to track procedure state.
+ (procedure): Optimize the trivial case at this level.
+ (internal_procedure): Re-implement in terms of proc_open,
+ proc_read, proc_close.
+ (proc_open) New function.
+ (proc_read) New function.
+ (proc_close) New function.
+ (write_case) Moved into proc_read.
+ (close_active_file) Moved closing of data source into proc_close.
+
+ * storage-source.c: Rewrote to conform with modified
+ case_source_class interface.
+
+ * transformations.c (trns_chain_execute): Added argument to allow
+ starting execution from an arbitrary transformation. Updated
+ callers.
+
+ * transformations.h (enum TRNS_NEXT_CASE) Renamed TRNS_END_CASE.

+
+ * sys-file-reader.c (read_display_parameters): Don't assume that
+ MEASURE_* and ALIGN_* have the same values found in system files.
+
+ * sys-file-writer.c (write_variable_display_parameters): Ditto.
+
+ * variable.h: Change MEASURE_NOMINAL, MEASURE_ORDINAL,
+ MEASURE_SCALE to be 0-based instead of 1-based. This also fixes
+ the value of n_MEASURES, which was off by 1 (at least from my
+ point of view).
