Thomas:

  Use the LCD's "set address" to move to the appropriate=
 coordinates, then just write the 3 bytes. Here is some code:

//=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
void LCD_Position_Cursor(ubyte x, ubyte y)
  {
  //Valid x is 0-15, valid y is 0-1
  if((x<=3D15)&&(y<=3D1))
    Write_LCD_Control(0x80|(y<<6)|x);
  }
//=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D
//Prints a 3 character string of input at the current location.
void LCD_put_dec(ubyte input)
  {
  ubyte
    digit;
  ubyte
    no_blank;
  digit=3Dinput/100;
  if(digit)
    {
    Write_LCD_Data(digit+'0');
    no_blank=3D1;
    }
  else
    {
    Write_LCD_Data(' ');
    no_blank=3D0;
    }
  input%=3D100;
  digit=3Dinput/10;
  if(digit|no_blank)
    Write_LCD_Data(digit+'0');
  else
    Write_LCD_Data(' ');
  Write_LCD_Data(input%10+'0');
  }
//=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=
