Using the Link3270 bridge

To run transactions using the Link3270 bridge, you must provide a client program that drives the Link3270 interface using LINK, EXCI LINK, or ECI requests. The message passed on each request determine the mode of operation, and the service to be performed.

To develop a client program to run an existing CICS® 3270 transaction using the Link3270 bridge you need to:

Establish the suitability of your applications for use with Link3270.
Design and write your client programs

CICS provides sample ECI, EXCI and LINK client programs to run the NACT sample transaction. You can use these as guidance in converting your own applications. See Link3270 sample programs for more information about the Link3270 samples and NACT.
