A system and method of managing displayed message priorities in an electronic price label (EPL) system (10) through a data file (28,32) containing message records including message priorities for each EPL (18) is provided. The system (10) includes a computer (12) which stores a plurality of records for an electronic price label (18) in the data file (28,32), which reads the data file (28,32) to identify all of the records for the electronic price label (18), which determines the priorities in the records, and which displays the messages at start times within the records in accordance with the priorities. The computer (12) records the records in response to operator input and/or inputs received from an application program through an application programming interface (26). For inputs received from application programs, the computer (12) establishes new priorities for the messages based upon different application priorities assigned to the application programs. <IMAGE> |
