Writing a 3270 bridge exit program

Considerations common to all user-replaceable programs

Note that the comments contained in General notes about user-replaceable programs apply to this section.

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 MQSeries® commands in a bridge exit so that CICS can GET and PUT messages to MQSeries queues.

For a detailed description of the 3270 bridge exit and its interfaces, see the CICS External Interfaces Guide.
