Input message formatting
Use the following information to format your MFS input messages.
Input messages accepted by MFS
Only input data from devices that are defined to IMS TM as operating with MFS can be processed by MFS. However, the use of MFS for specific input messages depends on the message content and, in some cases, on the previous output message.
How MFS formats input messages
Input data from MFS-supported devices in formatted mode is formatted based on the contents of two MFS control blocks—the message input descriptor (MID) and the device input format (DIF). The MID defines how the data should be formatted for presentation to the IMS TM application program and points to the DIF associated with the input device. The DIF describes the data as the data is received from the device.
