<p>man, running on 4 hours of sleep is killing me.<br />I can't even remember the MS-DOS interrupt to open a file! </p><p>I know reading it is int 21 ah=3f, closing it is int 21 ah=3d, and I'll never forget that seeking is int 21 ah=42, but how do you open a file?<br />I mean, not the int 21 ax=6c00 way, that one is only for DOS 4.0+, and obviously a game released in 1990 isn't gonna use that.</p>
