This article describes a high performance method for application generators to retrieve system messages. IMSADF II (Information Management Systems Application Development Facility Version 2) is the application generator which runs under IMS. Due to the large number of transactions processed by an application generator (millions per day), performance is critical to ADF. Also due to the frequency of message retrieval in both normal and error situations, the function of retrieving messages from the ADF system message data base is critical to the overall performance of ADF. For example, the message retrieval function is invoked seven times for the Primary Option Menu Screen alone, which is just one of several possible screens for a given transaction.
