IBM CICS

The IBM Customer Information Control System (CICS) is a widely installed transaction processing software system. A large number of transaction processing requirements running on mainframes today are handled by CICS systems. IBM designed CICS to support large numbers of terminals and a large transaction volume with fast and consistent response time. CICS can be described as an interface between CICS applications and the operating system.

CICS or CICS-compatible environments are now available for many platforms, including server support for OS/2, AIX, Windows NT, MVS/ESA, AS/400, HP-UX, Digital OSF/1, Siemens SINIX, Sun Solaris, and other UNIX platforms.

In supported environments, ACUCOBOL-GT offers the following features:

• Dynamic loading of shared libraries, including EXTFH libraries used for batch programs, so you can customize your environment by simply specifying an environment variable
• Debugging of CICS COBOL programs with the ACUCOBOL-GT runtime debugger
• The ability to interoperate with a wide variety of utilities that help you replicate mainframe functionality on open systems, such as external sort modules and utilities to handle complex calculations
