Returning a local array

I would like to return a local array. The below seems like the wrong way to do it: f[] := Module[{h}, h["a"] = 1; h["b"] = 2; h]; g = f[]; I would like g not to be associated with the local variable h, but equivalent to defining it as follows: g["a"] = 1; g["b"] = 2; Is it better to work with rules instead? It can become awkward and I would like to avoid it. f[] := Module[{h}, h={"a" -> 1, "b" -> 2}; h]; g = f[]; "a" /. g The specific problem is I am reading the header for a binary file that has 20 or so parameters describing the binary file. I thought this would be the analog of a structure in other languages and a good way to put these parameters in a variable. Thanks.
