/*
    This class is a basic extension of the Applet class.  It would generally
    be used as the main class with a Java browser or the AppletViewer.  But
    an instance can be added to a subclass of Container.  To use this applet
    with a browser or the AppletViewer, create an html file with the
    following code:

    <HTML>
    <HEAD>
    <TITLE> Logops </TITLE>
    </HEAD>
    <BODY>

    <APPLET CODE="Logops.class" WIDTH=283 HEIGHT=190></APPLET>

    </BODY>

    </HTML>

    You can add controls to Logops with Cafe Studio.
    (Menus can be added only to subclasses of Frame.)
