MFS message formats

Use these topics if your application programs communicate with devices by using Message Format Service (MFS).

Input message formats
MFS edits input data from a device into an IMS application message format using the message definition that the MFS application designer writes as input to the MFS language utility program. An input message consists of all segments presented to an IMS application program when the program issues a DL/I GU or GN call.
Output message formats
MFS edits output segments created by an IMS application program into a device format suitable for the device or remote program for which the message is destined.
MFS message formatting functions
IMS provides message formatting functions for MFS. The control blocks format messages for different device types.
