agreed, I also wasted time answering another question. :(
> Check if a variable contains only one letter
DB<106> $str='A B C'
=> "A B C"
DB<107> @matches= $str=~/([A-Z])/g
=> ("A", "B", "C")
DB<108> scalar @matches
=> 3
DB<115> $str='A B C'
=> "A B C"
DB<116> $str !~ /[A-Z].*[A-Z]/
=> ""
DB<117> $str=" A "
=> " A "
DB<118> $str !~ /[A-Z].*[A-Z]/
=> 1

Are you posting in the right place? Check out Where do I post X? to know for sure.

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).

Want more info? How to link
or How to display code and escape characters
are good places to start.
