+       * operations.def: Implement VALUELABEL function.  Add DATEDIFF,
+       DATESUM unimplemented stubs.
+
+       * parse.c (type_coercion_core): Add support for OP_var type, which
+       is a name for a numeric or string variable.
+       (is_compatible) New function.
+       (check_operator) Only require values to be compatible with their
+       expected types, not identical.
+       (is_valid_node) Ditto.
+       (compare_names) Always return mismatch if the command name can't
+       be abbreviated.
+       (lookup_function_helper) Pass the new OPF_NO_ABBREV flag to the
+       comparison function.
+
+       * generate.pl (init_all_types): Add support for a type just called
+       "var" that may be a numeric or string variable name.  Also, add a
+       no_abbrev option that prevents a function name from being
+       abbreviated (in case of naming conflict otherwise).
+       
+       * parse.inc.pl: Output OPF_NO_ABBREV flag.
+
+       * private.h: Add OPF_NO_ABBREV flag.
