This is functionally equivalent to the following:

	#include <bios.h>

	unsigned char Get_Scan_Code (void)
	{
	   if (!bioskey (1))
	     return 0;
	   return bioskey (0);
	}

Two notes about the original code:

	1) It doesn't test the shift status, so you cannot distinguish 
	   between 'a' and 'A'.

	2) In general, I'd advise to make the function return an int, not 
	   an unsigned char (it's a long story).
