A lot of people have already helped me, and yes I did read all of section 18
of the FAQ, but I still can't figure this out...

#include <dpmi.h>

#include <go32.h>

void display_string (unsigned short int x, unsigned short int y, unsigned
short int bg_color, unsigned short int text_color)
{

    char * disp_str = "Hello!";

    unsigned short int length = 6;

    // *****************************************************

    unsigned short int column = (x - 1);

    unsigned short int row = (y - 1);

    dosmemput (disp_str, __tb, length);

    __dpmi_regs output;

    output.x.ax = 0x1301;

    output.h.bh = 0x00;

    output.h.bl = ((text_color << 4) + bg_color);

    output.x.cx = length;

    output.h.dl = column;

    output.h.dh = row;

    output.x.es = (__tb >> 4);

    output.x.bp = (__tb & 0x0f);

    __dpmi_int (0x10, (& output));

};

int main (void)
{

    display_string (10, 10, 7, 1);

    return 0;

};

Any help would be greatly appreciated...
