// Imagine we have two separate JSON objects.
loJsonA = createobject("CkJsonObject")
loJsonA.UpdateString("ciphertext","encryptedData")
loJsonA.UpdateInt("status",200)
loJsonA.UpdateString("error","errorMsg")

loJsonA.EmitCompact = .F.
? loJsonA.Emit()

// jsonA contains:

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

loJsonB = createobject("CkJsonObject")
loJsonB.UpdateString("users[0].role","Surgeon")
loJsonB.UpdateNewArray("users[0].sub_roles")
loJsonB.UpdateBool("users[0].viewable_for_sharing",.T.)
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",.T.)
loJsonB.UpdateInt("users[1].eula_create_date",123)

loJsonB.EmitCompact = .F.
? 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
//     }
//   ]
// }

// First add an empty array at the desired location (-1 means append to end).
loJsonA.AddArrayAt(-1,"users")

// The destination is the empty "users" array, the source is the populated "users" array in jsonB.
loJsonUsersDest = loJsonA.ArrayOf("users")
loJsonUsersSrc = loJsonB.ArrayOf("users")
// Copy the array items from source to dest
loJsonUsersDest.AppendArrayItems(loJsonUsersSrc)
release loJsonUsersDest
release 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
//     }
//   ]
