(which didn't happen) All 16 color modes of the EGA and VGA available to QB arrange the video data in four seperate planes. Think of a 16 color mode as 4 B&W images thrown on top of each other... The problem you're having is that you don't tell the VGA which plane you want to read and write two - since QB's runtime libraries always leave all planes active for writes in between calls to graphics statements, the BLOAD you did above simply wrote to all planes (color 15 = bright white). This is off the top of my head- hope I got the OUT indexes right!
