I am planning to start learning lower-level programming with ada,
however, I was unable to find a solid tutorial on writing directly to
a memory address or interfacing with assembly. Does anyone know where
I can find a reference to some tutorials/information? Below is an
example of code I would like to be able to implement.

...
unsigned int print(char *message, unsigned int line)
{
	char *vidmem = (char *) 0xb8000;
	unsigned int i= 0;

	i=(line*80*2);

	while(*message!=0) // 24h
	{
		vidmem[i]= *message;
		*message++;
		i++;
		vidmem[i]= 0x7;
		i++;
	};

	return(1);
};
...
