INT 2F U - PC-Kwik Programs - API(Application Program[ming] Interface) The defined set of calls which a program may make to interact with or request services of the operating system or environment under which it is running.  Because the inputs and outputs of the calls are well-defined, a program using the API can continue using the identical calls even if the internal organization of the program providing the API changes.
	AH = CCh
	SI = 5453h or 7473h
	AL = function number (at least 00h,01h,04h,05h,07h,80h)
	DL = program identifier (see #03067)
Return: SI = 7473h
	other registers vary by function

	  thus supports this call
