I think the OP struggled over the difference between
...
my $txt='-UK 123 123-UK 123-UK 123-UK';
print "|$1| - match until pos:" . pos($txt) . "\n" while $txt=~/((?:\
+d+-UK\W?)+)/g ;
...
and
...
my $txt='-UK 123 123-UK 123-UK 123-UK';
print "|$1| - match until pos:" . pos($txt) . "\n" while $txt=~/((?:\
+d+-UK\W?)*)/g ;
...
which is the difference between (expr)+ and (expr)*,
the latter matching everywhere and (of course) at 'expr', the former
matching only at 'expr'.
(maybe I misinterpreted his intention)

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
