* Imagine we have two separate JSON objects.
loJsonA = CreateObject('Chilkat.JsonObject')
loJsonA.UpdateString("ciphertext","encryptedData")
loJsonA.UpdateInt("status",200)
loJsonA.UpdateString("error","errorMsg")

loJsonA.EmitCompact = 0
? loJsonA.Emit()

* jsonA contains:

* {
*   "ciphertext": "encryptedData",
*   "status": 200,
*   "error": "errorMsg"
* }

loJsonB = CreateObject('Chilkat.JsonObject')
loJsonB.UpdateString("users[0].role","Surgeon")
loJsonB.UpdateNewArray("users[0].sub_roles")
loJsonB.UpdateBool("users[0].viewable_for_sharing",1)
loJsonB.UpdateInt("users[0].eula_create_date",123)
loJsonB.UpdateString("users[1].role","Support")
loJsonB.UpdateString("users[1].sub_roles[0]","Tech")
loJsonB.UpdateString("users[1].sub_roles[1]","Service")
loJsonB.UpdateBool("users[1].viewable_for_sharing",1)
loJsonB.UpdateInt("users[1].eula_create_date",123)

loJsonB.EmitCompact = 0
? loJsonB.Emit()

* jsonB contains:

* {
*   "users": [
*     {
*       "role": "Surgeon",
*       "sub_roles": [],
*       "viewable_for_sharing": true,
*       "eula_create_date": 1649108922482
*     },
*     {
*       "role": "Support",
*       "sub_roles": [
*         "Tech",
*         "Service"
*       ],
*       "viewable_for_sharing": true,
*       "eula_create_date": 1649108951523
*     }
*   ]
* }

* Let's say we want to insert jsonB into jsonA to get this:

* {
*   "ciphertext": "encryptedData",
*   "status": 200,
*   "error": "errorMsg",
*   "users": [
*     {
*       "role": "Surgeon",
*       "sub_roles": [],
*       "viewable_for_sharing": true,
*       "eula_create_date": 1649108922482
*     },
*     {
*       "role": "Support",
*       "sub_roles": [
*         "Tech",
*         "Service"
*       ],
*       "viewable_for_sharing": true,
*       "eula_create_date": 1649108951523
*     }
*   ]
* }

* The destination is the empty "users" array, the source is the populated "users" array in jsonB.
loJsonUsersDest = CreateObject('Chilkat.JsonArray')
loJsonA.AppendArray2("users",loJsonUsersDest)

loJsonUsersSrc = CreateObject('Chilkat.JsonArray')
loJsonB.ArrayOf2("users",loJsonUsersSrc)

* Copy the array items from source to dest
loJsonUsersDest.AppendArrayItems(loJsonUsersSrc)

? loJsonA.Emit()

* The end result is this:

* {
*   "ciphertext": "encryptedData",
*   "status": 200,
*   "error": "errorMsg",
*   "users": [
*     {
*       "role": "Surgeon",
*       "sub_roles": [
*       ],
*       "viewable_for_sharing": true,
*       "eula_create_date": 123
*     },
*     {
*       "role": "Support",
*       "sub_roles": [
*         "Tech",
*         "Service"
*       ],
*       "viewable_for_sharing": true,
*       "eula_create_date": 123
*     }
*   ]
* }
