Determining whether the buffers are loaded

If you know that the buffers have already been loaded with the desired programmed symbols, you do not need to resend the entire load programmed symbols data stream.

To determine if the buffers are loaded with the desired programmed symbols, use one of these methods:

Maintain a handwritten log at the device and record the current status of the PS buffers.
Run a test transaction that attempts to use the desired programmed symbols. Either the desired transaction's output is successfully displayed or an error message (DFS2078) is sent to the terminal and the message is returned to the IMS message queue, with the terminal left in protected mode. The message must be dequeued and a transaction started to load the programmed symbols buffer.
