Comments:
When CALLFH is specified, all file I/O statements are converted to calls to the file handler specified by the parameter.
If handler-name is not specified, the module EXTFH is assumed.
This directive is also used to direct all file handling calls through converter modules, to make use of non-COBOL file handlers.
