ACUCOBOL-GT also includes a generic architecture for connecting to file systems. This means that developers can choose from a variety of file systems and database management systems, as shown in the following diagram:
On all platforms except VMS and OpenVMS, ACUCOBOL-GT is shipped with the powerful, performance optimized Vision indexed file system. On VMS and OpenVMS systems, ACUCOBOL-GT uses the native RMS file system. On HP e3000 emulators, in addition to Vision, ACUCOBOL-GT interfaces with KSAM files.
extend's interfaces to other file systems are licensed separately.
