   I understand how to use this template tag as shown here:
   http://codex.wordpress.org/Template_Tags/get_the_category#Show_the_First_Category_Name_Only
   If I use it twice with that [0] changed to something else (like 1 or 2) it will give me the other category names. Fine till here.

   Now, I was wondering if I would like to put dynamically a link (anchor) around the last part:
   $cat->cat_name so that it will become actually a link to that category... what code do I need? I can do it "hardcoded" but I would like to use something like the bloginfo(url)/cat_name - is it possible?
   Thanks!

   I get the feeling I'm not understanding your question. But I'll take a stab anyway.

   Is this what you're trying to do? (with extra spacing for clarity)

   <a href="<?php bloginfo('url'); ?>/category/<?php echo $cat->category_nicename; ?>">
   
   <?php echo $cat->cat_name; ?>
   
   </a>

   Or is that what you meant by doing it "hardcoded?"

   I'll try again...
   Here is the code in the Codex:
   

   <?php
   $cat = get_the_category(); $cat = $cat[0]; echo $cat->cat_name;
   ?>

   If a post is in more than one cat - it will display only the first one and as NOT a link (that's the nature of this template tag)

   Now, if I use the same tag twice in the Loop, once with [0] and the second time with [1] it will display
   1. the first cat
   2. the other cat the post is in.

   What I want/would like: to make the displayed category names (in both cases) a link to the category (archive), as the_category would do.

   Is it clearer?

   Thanks for trying :)

   Something like this, where $which is an integer for the category you want?

   <?php
   function one_category($which=0){
     $cat = get_the_category();
     $cat = $cat[ $which ];
     $link = '<a href="' . get_bloginfo('url') . '/category/' . $cat->category_nicename . '">';
     $link .= $cat->cat_name;
     $link .= '</a>';
     echo $link;
   }
   
   one_category( 0 ); // a link to the first cat
   one_category( 1 ); // a link to the second cat
   
   ?>

   If I'm still misunderstanding, then I'll let somebody else have a try.

   <?php
   $cat = get_the_category(); $cat = $cat[0];
   ?>
   <a href="<?php echo get_category_link($cat);?>"><?php echo $cat->cat_name; ?></a>

   ...???...

   mdi, it's posts like yours that remind me that even though I know a bit of PHP, I sure don't know all the functions available in WP. I'm feeling a bit daft right now.

   But note that get_category_link() needs the cat ID as an argument, so that portion of your code should say

   <?php echo get_category_link($cat->cat_ID);?>

   Not exactly but it helped me a lot! Thanks.

   So, here is what I ended up:
   1st instance:
   

   <?php
   $cat = get_the_category(); $cat = $cat[0]; echo '<a href="' . get_bloginfo('url') . '/category/' . $cat->category_nicename . '">';
   echo $cat->cat_name;
   echo  '</a>';
   ?>

   ...other stuff here...
   2nd instance:
   

   <?php
   $cat = get_the_category(); $cat = $cat[1]; echo '<a href="' . get_bloginfo('url') . '/category/' . $cat->category_nicename . '">';
   echo $cat->cat_name;
   echo  '</a>';
   ?>

   It can be used for example to display one category before the post content and another cat after the content.

   Thanks again, Adam.

   Oops...
   I just noticed the code posted by mdi - thanks!
   That's simpler and nicer than mine and it does the same :)

    The code below worked for me too:

    <?php echo get_category_link($cat=#);?> (# is the cat number)
