1.11.3 COBOL Mode

For COBOL-IT, only SUBSYS mode is supported. For Microfocus, there are seven supported COBOL modes:
  • MF_SUBSYS
  • MF_COBFUNC
  • MF_NOCANCEL
  • MF_DEFAULT_CANCEL
  • MF_PHYSICAL_CANCEL
  • MF_LOGICAL_CANCEL_STANDARD
  • MF_LOGICAL_CANCEL_SPECIAL

The default value is MF_SUBSYS. For more information, see Environment Variables.

These COBOL modes are set through the environment variable ARTIMS_COBOL_MODE, or set in the CLOPT of each BMP/MPP server in the UBBCONFIG file. The CLOPT parameter is -m COBOL_MODE (for example, -m MF_SUBSYS).

There are four COBOL mode configuration combination rules:
  1. No environment variable setting, CLOPT. MF_SUBSYS is the default.
  2. When only using environment variable settings, all servers must be controlled by the environment variable.
  3. When only using CLOPT, everything is controlled by CLOPT.
  4. When using an environment variable and CLOPT, CLOPT takes precedent.
