MFS output message formats
The output message format is used to define what segments and fields MFS will receive from the application program.
If using option 1 or option 2, the output message format is the same as it is for input messages. Present all fields and segments to MFS. You can present null segments. All fields in output messages are fixed length and fixed position. Output messages do not contain option numbers.
Option 3 output messages are similar to input messages, except that they do not contain option numbers. The program submits the fields as required in their segments with the position information.
