ds_map_default_value

Returns the value of a key from a given map, inserting a default value into the map if the key does not yet exist.

map = ds_map_create();
map[? "Hello"] = "World";
map[? "Goodbye"] = "Cruel World";

A = ds_map_default_value(map, "GML", "Scripts");       // A == "Scripts"
B = ds_map_default_value(map, "Hello", "I Love You");  // B == "World"

//  resulting map:
//  {
//      GML: "Scripts"
//      Hello: "World"
//      Goodbye: "Cruel World"
//  }
