MFS input examples

The following figures provide examples of MFS input.

In the following examples, three DPAGEs are defined:
  • DPAGE 1 defines data for 2 segments
  • DPAGE 2 defines data for 1 segment
  • DPAGE 3 defines data for 3 segments

Three LPAGEs are created for the message. A data descriptor function management header with a DSN supplied with each chain is used to select each DPAGE. The first DSN name selects DPAGE 1, the second DSN name selects DPAGE 2, and the third DSN name selects DPAGE 3.

Figure 1. Example of autopaged input, three chains
Figure shows multiple arrows between IMS and OTHER with various labels on the arrows, such as ATTACH DPN=,data,FIC,(BB)(note), data,LIC, and others.

A data descriptor FM header can precede the data.

Three LPAGEs are created for the message. A conditional test on the data is performed to select each DPAGE. Results of first test selects DPAGE 1, results of the second test selects DPAGE 2, and results of the third test selects DPAGE 3.

Figure 2. Example of autopaged input, single transmission chain
Figure shows multiple arrows between IMS and OTHER with various labels on the arrows, such as ATTACH DPN=,(note),data,FIC,(BB/EB), data,MIC, and others.

The data descriptor FM header can be sent to select one DPAGE only. The ATTACH indicates a multichain message.
