        <para>The current figure is the destination of the graphic drawing. The
            <literal>scf</literal> function allows to change this current figure or to
            create it if it does not already exist.
        </para>
        <para/>
        <para>
            <literal>scf(num)</literal> set the figure with <literal>figure_id==num</literal>
            as the current figure. If it does not already exist it is created.
        </para>
        <para/>
        <para>
            <literal>scf(h)</literal> set the figure pointed to by the handle
            <literal>h</literal> as the current figure. If it does not already exist it is
            created.
        </para>
        <para>
            <literal>scf()</literal> is equivalent to <literal>scf(max(winsid())+1) </literal>.
            It may be used to create a new graphic window.
