ART CICS Runtime supports COBOL programs compiled with different COBOL compilers. Refer to Supported Platforms for the COBOL compilers ART CICS Runtime supports. COBOL runtime is required in order to run COBOL programs in ART CICS Runtime.

Some ART CICS Runtime features are specific to certain COBOL compiler.

If COBOL-IT is used:

• COBOL programs should be compiled with -fthread-safe option.
• When you upgrade the version of COBOL-IT runtime, you may require recompiling the COBOL programs with the new version of COBOL-IT compiler.

If Micro Focus Visual COBOL 2.2 is used, we recommend you set COBOL runtime tunable parameter subsystem_cancel_mode=1, which specifies logical cancel for CBL_SUBSYSTEM cancels. See Micro Focus documentation for more information.
