Chapter 20. Writing a 3270 bridge exit program

Considerations common to all user-replaceable programs

Note that the comments contained in Chapter 5, “General notes about

user-replaceable programs,” on page 435 apply to this chapter.

The 3270 bridge provides an interface so that you can run 3270-based CICS

transactions without a 3270 terminal. In the bridge environment, terminal commands

are intercepted by CICS and passed to a bridge exit user-replaceable program.

The bridge exit provides the mechanism by which data needed to run a 3270

transaction can be sent and received from an external resource. For example, you

can use WebSphere

MQ commands in a bridge exit so that CICS can GET and

PUT messages to WebSphere MQ queues.

For a detailed description of the 3270 bridge exit and its interfaces, see Bridging to

3270 transactions, in the CICS External Interfaces Guide.
