I thought sysopen can't be mixes with print/read, as buffered IO and unbuffered cannot be mixed? And I mentioned that I don't want to use syswrite
Or sysopen is not about unbuffered IO (in opposite to syswrite) ?
(Note that your code still unconditionally truncates the file each time.)
Ok, could you please example why? First file open mode is append, and second is read (read/write)

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).
