Using AR/CTL common calls

This section describes how to use AR/CTL common calls to obtain checkpoint/restart services. These calls are valid in all environments that AR/CTL supports. You can use AR/CTL common calls and AR/CTL-format checkpoint restart calls in the same program, or you can use AR/CTL common calls and IMS format checkpoint restart calls in the same program.
