<p>Dot_List_Reset ($F2DE)</p>

<p>This routine draws a series of dots, specified by the list
pointed to by the X register. The list has the following format: </p>

<blockquote>
    <p>mode, relative y, relative x,</p>
    <p>mode, relative y, relative x,</p>
    <p>. . .</p>
    <p>. . .</p>
    <p>mode, relative y, relative x</p>
    <p>0x01</p>
    <p>&nbsp;</p>
</blockquote>

<p>This routine will continue to traverse the list, until a mode
&gt; 0 is encountered; at that point, it will reset the zero
reference (the integrators). </p>

<p>&nbsp;</p>

<p>ENTRY:</p>

<blockquote>
    <p>DP = $D0</p>
    <p>X-reg points to the dot list</p>
</blockquote>

<p>&nbsp;</p>

<p>EXIT:</p>

<blockquote>
    <p>X-reg points to next byte after the terminator</p>
    <p>D-reg trashed</p>
</blockquote>
