Hi i want to do the following in djgpp but i having problems is there anyone
out there that can help by perhaps offering a good tip or just a little piece
of code?


Macros that extract the segment and the offset from a far pointer (called
`FP_SEG' and `FP_OFF')
	poke(0x0000, 0x010e, FP_SEG(font));
	poke(0x0000, 0x010c, FP_OFF(font));
}

////////////////////////////////////////////////////
// OLDFONT								//
// ReInstalls user's original font pointer		//

void OldFont()
{
	poke(0x0000, 0x010e, FP_SEG(UserFont));
	poke(0x0000, 0x010c, FP_OFF(UserFont));
}
