print "$+{first} $+{last}\n"
if m/^
(?<last> [^%]+ ) %
(?<first> [^%]+ ) %
(?<id> A [^%]+ )
/x;
Really, the critical component is to use a negated character class to match anythig that is not the delimiter, rather than relying on non-greedy specifications.
If your Perl is old enough to not have named captures, this is equivilent code that is more universally compatible:
print "$2 $1\n"
if m/^([^%]+)%([^%]+)%(A[^%]+)/;
Update: Added /x and nicer formatting.

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).
