After reading posts, I realized my error in using split, so I rewrote and simplified to:
while ($_ = substr($foo,$i++,1)){
if (++$_**2 == 0) {
print "$foo Contains Alpha Characters\n";
last;
}
}
This is better I think. Cameron
UPDATE: I have updated the code with the suggestions offered by ambrus. Thanks for pointing that out... ambrus I reverted to the original code, and am posting the changes below.
Updated with ambrus suggestions:
my $i = 0;
while (local $_ = substr($foo,$i++,1)){
if (++$_ == 0) {
print "$foo Contains Alpha Characters\n";
last;
}
}
I optimized further:
while (++substr($foo,$i++,1) != 0){}
This breaks at an alpha char, and significantly increases the speed, but it is still ~3 times slower that initial solution.

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).
