Configuring the Micro Focus File Handler to Call RM/COBOL Data Files

To use an RM/COBOL data file in your source code, you can configure the Micro Focus File Handler to call the RM/COBOL file handler.

To configure Studio Enterprise Edition to use an RM/COBOL data file:

Set the CALLFH(ACUFH) Compiler directive.
Note: Access to the RM/COBOL file handler is routed via Vision, the ACUCOBOL/GT native indexed sequential file system.
Set environment variable A_CONFIG to the path of a configuration file:
```
set A_CONFIG=acurmfm.cfg		*> acurmfm.cfg is your configuration file.
```
In acurmfm.cfg, set the file handler:
```
DEFAULT_FILESYSTEM RMFM
```
