Try this:
sub test2
{
my ($var2) = shift;
# Perl can implement the if/else idea very code efficiently.
return ("One") if ($var2 =~ /^1\./ );
return ("Two") if ($var2 =~ /^2\./ );
return ("Three") if ($var2 =~ /^3\./ );
return ("UNKOWN");
}
print test2 ("1.00.000"), "\n";
print test2 ("11.00.000"), "\n";
print test2 ("3.abc"), "\n";
__END__
prints:
One
UNKOWN
Three
Update:
Well I think we both know that this is a simple example.
The regex'es aren't complicated. Just to demo the idea.

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.
