List page - if category not in URL, display alternate heading

I've searched the form, but am not able to find this topic. What I'm trying to achieve is:

1. If the URL to the list page viewer contains a category num, I would like the page heading on the list viewer page to display 'CategoryName News'.
2. If the URL does not contain a category num, I'd like the page heading to display just 'News'.

What's happening with my current code is that if there is not a category num in the URL, the page displays the last updated category title instead of nothing.

LINKS TO VIEWER PAGE:

A) Display news articles filtered by category in URL:
<a href="/news/index.php/category-<?php echo ($record['num']) ?>/">
(Shows selected page title category, as intended.)

B) Display all news articles:
<a href="/news/index.php">
(Shows a page title even if no category is in URL.)

VIEWER PAGE CODE:

---- HEAD ----
// 'news' list
list($newsRecords, $newsMetaData) = getRecords(array(
'tableName' => 'news',
'orderBy' => "posting_date DESC",
));
// category title for pg heading
list($newsRecordsHDG, $newsMetaData) = getRecords(array(
'tableName' => 'news',
'limit' => '1',
'where' => whereRecordNumberInUrl(1),
'allowSearch' => true, // also tried as false
));

---- HTML ----
<?php if ($newsRecordsHDG): ?>
<?php foreach ($newsRecordsHDG as $record): ?><?php echo $record['category:label'] ?><?php endforeach ?>
<?php endif ?> News

Desired HTML output:

If category num in URL = 'Category News'

If no category num in URL = 'News'

I hope I've explained myself well enough. Thanks for looking and especially for any help!
