73. Interlacing in modes 0-6 ~~~~~~~~~~~~~~~~~~~~~~~~ Turning the interlacing off can produce a much steadier picture. This is done using the *TV command, which is only partly explained on page 23 of the User Guide. The full syntax is *TV A,B , where A determines how many lines up or down the display is moved, and B determines whether the i/l is turned on or off. Thus, to leave the picture as it is, but to turn the i/l off, you use *TV0,1. To move the picture down one line as well, you use *TV255,1. To move the display, but keep the i/l on, you would use *TV255,0 , which can be shortened to the familiar *TV255. To restore the display to normal, ie. i/l on and no shift, you use *TV0,0, which can be shortened to just *TV. Don't forget that the commands will have no effect until you change Mode, and that the interlacing always stays on in Mode 7.
