Managing virtual storage for subprograms - changing COBOL application programs

AR/CTL provides the Subprogram Virtual Storage (ARCSPVS) application program interface (API) for managing defined areas of virtual storage for any application program, including a subprogram, in a restartable environment. If an application subprogram already uses the subprogram support that is provided with the QUICKSTART for MVS product, no program changes are required for the use of AR/CTL support for subprograms. For more information, see QUICKSTART-to-AR/CTL bridge.
