Overview of changing COBOL application programs
The easiest way to obtain
AR/CTL
services in an application program is with automated methods, which require no program changes. If you are not able to use automated methods, you can change the application program to issue explicit requests for
AR/CTL
services. This section provides general information about making changes to application programs written in COBOL.
Before using the information in this section, review the overview information about AR/CTL checkpoint/restart and data services in Using-AR-CTL-checkpoint-restart-services.
