* This is our initial JSON:

*   "abc": {

*     "def": "1234",
*     "aaa": "1234"
*   },
*   "ghi": "1234",
*   "nmo": "1234"
* }

* Sort the top-level JSON object by key.
lnAscending = 1
lnCaseSensitive = 1
loJson.Sort(lnAscending,lnCaseSensitive)

* Look at the sorted JSON..
? loJson.Emit()

* {
*   "abc": {

*   "ghi": "1234",

* }

* Now sort the members of the "abc" object..

loJson.ObjectOf2("abc",loJsonAbc)

loJsonAbc.Sort(lnAscending,lnCaseSensitive)

* Now look at the JSON with the members under "abc" also sorted..
