if( $line =~ m[^REM $sTest\s*$]i ) {
If you use the //, then you don't need the "m" in front, but otherwise its just style preference.
There is one other fine point about this, if $sTest could contain some characters that would normally mean something to the regex engine, like a "(" or whatever, you can specify to interpret the string $sTest literally - meaning ignore the meaning of those characters. This is done by surrounding $sTest with a \Q \E pair.
if( $line =~ /^REM \Q$sTest\E\s*$/i ) {

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).
