Yours is closest to the way I would do it. My approach would probably be to use a Finite State Machine, but otherwise works the same way.
Since Rhodium has said s/he wants to do a search and replace, I presume that the rest of the file should be preserved. For example, run this script with 'prog file >out_file':
#!/usr/local/bin/perl -w
my $inblock = 0;
while (<>) {
if ($inblock ) {
if (/^\*END/ ) {
$inblock = 0;
}
else {
s/expression_to_find/replace_with/g; # e.g.
}
}
elsif ( /^\*DESCRIPTION ) {
$inblock = 1;
}
print; # print $_ implicitly
}
Nothing fancy, just does the job

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).
