Object.Queue
Object.Queue [= Value]
Integer
Only one queue at a time can be assigned for forms, sets, and batches. If the Object corresponds to a Set or Batch, and the Forms in this Set/Batch are placed in different queues, the Queue property has the value ehMultipleQueues. So you can only assign one queue, but you can read multiple queue values.
