Thank you to everyone for help in resolving this issue. The syntax for determining if tArray[“status”] contains data or an array appears to be either:
If the value of tArray[“status”] is not empty // contains data or If tArray[“status”] is not an array // contains data If I remember correctly, LC arrays are implemented as associative arrays (key, value pairs). I assume that they are implemented as hash tables as opposed to trees?
