        * re.c (reflags2str): Ditto.

 +
 +      Introduce new Nnull_array_value NODE equivalent to Nnull_string that
 +      is used to mark an array element that was referenced without assigning
 +      a value. We can then recognize Nnull_array_value to allow a subarray
 +      to be instantiated later instead of requiring it to be scalar. This
 +      eliminates a class of fatal errors that make tricky to work with
 +      multidimensional arrays.
 +
 +      * awk.h (isnull): New macro to test whether a NODE is either
 +      Nnull_string or Nnull_array_value.
 +      (Nnull_array_value): Declare new special node.
 +      (var_uninitialized): Use isnull instead of comparing to Nnull_string.
 +      * array.c (value_info): Ditto.
 +      * awkgram.y (valinfo): Add case for Nnull_array_value.
 +      * builtin.c (do_typeof): Show Nnull_array_value as untyped.
 +      * cint_array.c (leaf_lookup): Initialize element value to
 +      Nnull_array_value instead of Nnull_string.
 +      * debug.c (print_memory): Add case for Nnull_array_value.
 +      * gawkapi.c (node_to_awk_value): Eliminate paranoid tests that
 +      values with both NUMBER and STRING set are actually Nnull_string,
 +      since they could now also be Nnull_array_value.
 +      * int_array.c (is_integer): Use isnull instead of comparing to
 +      Nnull_string.
 +      (int_insert): Initialize element value to Nnull_array_value instead of
 +      Nnull_string.
 +      * interpret.h (Op_sub_array): If the current node value is
 +      Nnull_array_value, create an array instead of issuing a fatal error
 +      about using a scalar as an array.
 +      * main.c (main): Initialize Nnull_array_value.
 +      * node.c (str2wstr): Use isnull instead of comparing to Nnull_string.
 +      * str_array.c (str_lookup): Ditto, and initialize new element values
 +      to Nnull_array_value instead of Nnull_string.
 +
+ 2021-12-08         Andrew J. Schorr      <aschorr@telemetry-investments.com>
+ 
+       * gawkapi.c (api_sym_update): Allow undefined Node_var_new variables
+       to be converted to arrays, otherwise API functions have no way
+       of creating an array that is referenced in an undefined fashion in
+       the program. This is somewhat comparable to how the set_argument
+       API allows an undefined argument variable to be converted to an array.

        * builtin.c (efwrite): Don't use return in call of function
