INT 2F U - Micro Focus COBOL v3.1.31 internal - ???                             
	AH = 97h
	AL = function
	    00h installation check
		Return: AL = FFh if installed
	    08h get ???
		Return: AL = ???
			BX = ???
			DX = ???
			AH destroyed
	    20h get ???
		Return: AX:BX = far entry point of ???
			CX = segment of ???
	    80h ???
		Return: ???
Notes:	Micro Focus COBOL compiler v3.1.31 and companion programs supply
	  these functions for internal use; these programs call the
	  installation check at startup (before installing the INT 2F
	  handler) and crash the system if a not authorized program answers
	  with AL=FFh
	the handler checks AL only if an internal flag is 1, otherwise ???
