Standard loop oly returning one page

Hi

I am reading, learning and experimenting with THE LOOP – using my Wamp localhost as the test area.

I am trying to develop a Page which will display a list of my existing pages.

I am struggling to understand 2 things:

1: When I use the standard loop:
[ Moderator Note: Please post code or markup snippets between backticks or use the code button. ]

<? php if ( have_posts() ) : ?>
 <? php while ( have_posts() ) : the_post(); ?>
 <?php the_title();?>
 <?php the_time( 'D  M   Y');?>
 <? php endwhile; ?>
 <? php endif; ?>

My loop only returns 1 page (the current page)
When I use the Custom loop using:

<?php $myPosts = new WP_Query( 'post_type=page' );

The results are fine and show more than 1 page

2 The output with the custom loop is limited to 10 items, even though I have 30 published posts and pages – can someone tell me where to look to understand how to get all 30 to appear.

Thanks
PAul
