Abstract
A data processing system includes a digital computer that has a plurality of data processing programs. A set of upgraded stations is coupled to the computer which generate messages that employ a relatively simple format to select the data processing programs; and a set of older stations is also coupled to the computer which generate messages that employ a complex format to select the data processing programs. A message routing program in the computer receives all of the messages from the stations, analyzes each message that has the simple format to identify the selected data processing program, and sends the message directly to the selected program. By comparison, the message routing program sends each message that has the complex format to a secondary routing program; and this secondary routing program analyzes each message which it receives, identifies the selected data processing program, and sends the message to the selected program. When the message routing program, the secondary routing program, and the data processing programs are executed sequentially within the computer in respective time intervals, the average time to process a message with a simple format from an upgrade…
