<P>Anyway, the choice of how to load the DAC is yours. Given that I&#146;m not providing you with any hard-and-fast rules (mainly because there don&#146;t seem to be any), what you need is a tool so that you can experiment with various DAC-loading approaches for yourself, and that&#146;s exactly what you&#146;ll find in Listing 34.1.

<P>Listing 34.1 draws a band of vertical lines, each one pixel wide, across the screen. The attribute of each vertical line is one greater than that of the preceding line, so there&#146;s a smooth gradient of attributes from left to right. Once everything is set up, the program starts cycling the colors stored in however many DAC locations are specified by the <B>CYCLE_SIZE</B> equate; as many as all 256 DAC locations can be cycled. (Actually, <B>CYCLE_SIZE</B>-1 locations are cycled, because location 0 is kept constant in order to keep the background and border colors from changing, but <B>CYCLE_SIZE</B> locations are <I>loaded</I>, and it&#146;s the number of locations we can load without problems that we&#146;re interested in.)</P>
