+ (dict_class_to_name): Move here.
+
+ * dict-class.h: New file.
+ (enum dict_class): Move here. Change from consecutive integers to
+ consecutive bits, to make testing for any of multiple values
+ easier. Add new DC_ALL constant.
+
+ * dictionary.c (struct dictionary): Change `case_limit' from
+ size_t to casenumber.
+ (dict_get_vars): Make final argument an enum dict_class.
+ (dict_get_vars_mutable): Ditto.
+ (dict_get_case_limit): Change return value to casenumber.

+ * missing-values.c (mv_add_num_range): Rename mv_add_range.
+ Simplify implementation.
+ (mv_has_value): Simplify implementation.
+ (mv_pop_value): Remove the first value, not the last, to avoid
+ having GET followed by SAVE reverse the order of missing values.

+ (mv_has_range): Simplify implementation.
+ (mv_peek_range): Rename mv_get_range.
+ (can_resize_string): Removed.

+ (mv_resize): Use value_resize.
+
+ * short-names.h (SHORT_NAME_LEN): Move here.
+
+ * val-type.h: New file, for definitions related to type and width
+ of abstract values. Before, these definitions were mixed among
+ those related to "union value" and those related to variables.

+ (macro LOWEST): Move here.
+ (macro HIGHEST): Move here.
+ (macro MAX_STRING); Move here.
+ (enum val_type): New enum with values VAL_NUMERIC and VAL_STRING.
+ Replaces enum var_type that had values VAR_NUMERIC and VAR_STRING.
+ All references updated.
+ (val_type_is_valid): New function. Replaces var_type_is_valid.
+ All references updated.
+ (val_type_from_width): New function. Replaces
+ var_type_from_width. All references updated.
+
+ * value-labels.c (val_labs_copy): Renamed val_labs_clone. All
+ references updated.
+ (val_labs_can_set_width): Use value_is_resizable.
+ (val_labs_add): Simply return false if the value labels set is too
+ wide, instead of having undefined behavior.
+ (val_labs_replace): Ditto.
+ (val_labs_replace): Ditto.
+ (val_labs_first): Set iterator to null if iteration is complete.
+ (val_labs_first_sorted): Ditto.
+ (val_labs_done): Become a no-op if the iterator is null.
+
+ * value.c (value_is_resizable): New function.
+ (value_resize): New function.
