Thanks, Lewis...

BTW, PACER.EX is Mark Akita's program. Seems Rob can run the code
unaltered... Is that correct, Rob? If this is true, why would it break on my
machine?

I noticed in the PACER.EX code that

    i1 = vesa_mode(640,480,16)

is called prior to

    clear_screen()

So does vesa_mode not actually set the graphics mode?
