Stop loop in page.php

Hi,
I’ve got a problem with my page.php loop.
I’ve got three columns on that site – 1 – main and 2 at the bottom. I’m executing the loop for the main column using standard <?php if (have_posts()) : while (have_posts()) : the_post(); ?> end end it using <?php endwhile; endif; ?> before 2 columns at the bottom. The problem is that the full content of all of the posts are visible and i’d like the full content to be shown only for the 1 column and the for the both on the bottom to show the ‘more’ hyperlink … Is there a way to stop the main loop or any other solution ?
