Hi @rocks,
The sort function has two modes. One is numeric sort and the other is lexical sort. An example of each is below:
#!/usr/bin/perl -w
use strict;
my @array = ( 2, 5, 17, 1, 28, 30, 100, -1 );
my @array2 = ( 'x', 'v', 'z', 'p', 'a', 'b' );
my @array_sorted = ();
my @array2_sorted = ();
@array1_sorted = sort { $a <=> $b } @array;
@array2_sorted = sort { $a cmp $b } @array2;
print "@array1_sorted\n";
print "@array2_sorted\n";
__OUTPUT__
C:\perl>perl p5.pl
-1 1 2 5 17 28 30 100
a b p v x z
C:\perl>
Hope this helps,
-Katie.

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).

or How to display code and escape characters
are good places to start.
