I have been using code similar to the following to read the joystick, but I
want to know whether this is a 'legal' method. I know it works on TOS 1.0 and 
1.4 (Yes you can get TOS 1.4 in Oz now 8-) but I haven't tested it on other
versions of TOS and I would like to be able to sure it will work with future
versions.

Here is the code:

-------
#include <osbind.h>

main()
{	int 	i;
	int 	*loc;
	long 	*ssp;
	
	loc = 0xfffc02;

	ssp = Super(0);  
	for (i = 0; i < 500; i++)
	        printf("%d    %d\n ", Bconin(4), *loc);

	printf("turning off mouse.\n");
	Bconout(4, 0x12);

	printf("turning joystick on.\n");
	Bconout(4, 0x14);

	for (i = 0; i < 500; i++)
	        printf("%d    %d    %x\n ", Bconin(4), *loc, *loc);

	printf("Turning mouse on.\n");
	Bconout(4, 0x08);
	Super(ssp); 
}
-------

By the way the Bconin doesn't seem to provide anything useful, just a constant
value.
 Thanks in advance for any help,
