Hi Everyone,
I am sorry to have to ask what is probably a silly question
but I am unable to figure out the conversion to djgpp for this 
snippet I have looked at the faq but I have spent most of my time 
programming windows so I have no dos programming experience.
the code comes from a C tutorial.
any help would be appreciated 
Regards

Steven Watson

void print(char *str)
{
	/* 
	   Prints characters only directly to the current display page
	   starting at the current cursor position. The cursor is not
	   advanced. 
	   This function assumes a colour display card. For use with a
	   monochrome display card change 0xB800 to read 0xB000
	*/

	int page;
	int offset;
	unsigned row;
	unsigned col;
	char far * ptr;

	page = activepage();
	curr_cursor(&row,&col);


	offset = page * 4000 + row * 160 + col * 2;

	ptr = MK_FP(0xB800,offset);

	while(*str)
	{
		*ptr++= *str++;
		ptr++;
	}
}
