You always have to be quick, otherwise you'll end up with Windows. OG>> IN ROM! I erased it in vain. :) OG>> Take it again, fascist: KF> I don't know what your program does. See for yourself: Fills a 512-byte table with addresses. The first 192 words are filled in addresses on the screen, the rest are filled with zero.
