Perl offers an abundance of looping and control statements.
Some quick notes if you're a C, C++, or Java programmer Perl
requires curly braces around blocks of code even if your for loop
has only one line of code.
Secondly, if you're new to programming these control statements test
whether a statement is true of false and then control execution of
the program based on the results. You might want to look at what is true and false in Perl?
Or you can dive right into the control statements
if statements
unless statements
while loops
until loops
do while loops
do until loops
for loops
foreach loops

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).
