You can use this to ensure the player enters the right number of letters (like 3 letters for a high score table). Quite useful for 'string parsing' with other commands.</td></tr></table><p class='header'>Example: <br><br><table width='100%' border='0' cellspacing='2' cellpadding='2' align='center'><tr><td>name$="Shane Monroe"<br>
