David, it's inline assembly, just take the part from label: and apply the
ASM2EU program to make it in euphoria. After poking it into memory and
calling it, it will return exactly when an fresh screen has been displayed,
so if you poke to VGAmem the results will not flicker. This works fine in
compiled languages.. but don't know in Euphoria because speed is required
for syncronicity.
