INT 2F R - InterWave Game 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. - GET NUMBER OF INTERWAVE PROGRAMS / PROGRAM ID
	AX = CD01h
	BX = 0000h
Return: BX = number of programs currently installed on the Game 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.
Desc:	get the number of programs supporting the InterWave Game 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. which are
	  currently installed in memory, which also forms the next program ID
	  number if the caller wishes to go resident on the 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.
Range:	AH=CDh-ECh, selected by scanning for an available multiplex number
Notes:	the first program to install on the IW Game 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. must use ID 00h
	the AMD-recommended implementation is for the handler to increment
	  BX and chain to the previous handler (if any), but this will fail
	  if TSRs are unloaded out-of-order
