SQM/SQR - Schedule Query Message and Response (Event S25)

Original Mode record-oriented query transactions are initiated from the querying application using the Schedule Query (SQM) to request information about a filler application's schedule(s). The filler application responds to these requests, using the Schedule Query Response (SQR) message to either return the requested information, or to signal that an interfacing error of some kind has occurred. The definitions for the SQM message and the SQR response are listed below.
