LOCAL oJson
LOCAL oJarr

oJson := CreateObject("Chilkat.JsonObject")
oJson:Load('{ "name": "John", "marbles": 100 }')

oJarr := CreateObject("Chilkat.JsonArray")
oJarr:Load('[ 1, 2, 3, "apple", "orange", [ 10, 20, 30 ], { "name": "Luther"} ]')

//  Copy the contents of jar to a new array member named "stuff".
//  Insert the array at the 2nd position
oJson:AddArrayCopyAt(1, "stuff", oJarr)

? oJson:Emit()
//  Expected output is:  {"name":"John","stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Luther"}],"marbles":100}

//  Note: The contents of the array were copied.
//  If we modify the contents of jarr, it does not modify the array contained within "json" because it is a separate copy.
//  For example:
oJarr:AddIntAt(-1, 2020)
? oJarr:Emit()
//  Expected output: [1,2,3,"apple","orange",[10,20,30],{"name":"Luther"},2020]

? oJson:Emit()
//  Remains unchanged: {"name":"John","stuff":[1,2,3,"apple","orange",[10,20,30],{"name":"Luther"}],"marbles":100}
