    <div class="pcw-text-body">
      You have probably noticed how LocoScript manages to underline characters on screen and display text in reverse video, and you might wonder how this is achieved. With a bit of cleverness, you can add some life to your dull text screens this way.
    </div>
    <div class="pcw-text-body">
      To underline text, print (using <strong>PRINT</strong>) the characters <strong>CHR$(27)"r"</strong> before displaying it, and then <strong>CHR$(27)"u"</strong> to disable underlining.
    </div>
    <div class="pcw-text-body">
      Similarly, for reverse video, print (<strong>PRINT</strong>) <strong>CHR$(27)"p"</strong> at the beginning and <strong>CHR$(27)"q"</strong> afterwards.
    </div>
    <div class="pcw-text-body">
      As a final touch, the command <strong>PRINT CHR$(7)</strong> makes the PCW emit a beep. A good idea is to place a "beep" command just before an <strong>INPUT</strong> statement, to remind users that they are expected to type something.
    </div>
