Thanks very much. There is a lot I don't know about perl, and even more so about 'modern' perl since I only dive into programming about once per year.
I had in fact discovered the s/char//g trick after making the OP.
Those 'set' operations look very useful. I will have to study up on them.
In this case I am not (yet) sure they will work, since a suit like "AKQxxx" is valid but one like "AAKxxx" is not. (There is only one Ace of spades for example.) So assuming counting members of the set AKQ would return 3 in both cases(??), but the second is invalid.
But no doubt I will find a use for set operations now that I know they are available.

PS.
I have 'discovered' (I am sure I am not the first!) that a way to avoid destruction of the original string is to use $&
as in $deal =~ s{ AKQJ}{$&}xg; will count the number of top cards in $deal, but leave it unchanged:
</code> $deal="AQTxx"; $c = $deal =~ s{ AKQJ}{$&}xg; print "$c, $deal\n";
output: 2, AQTxx

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).
