Uh, no, you can't print a "backspace" to an html text area. The best you could do is some form of javascript, which I won't get in to here.
As for your second question, the if BLOCK form is the canoical and the best way to write that, but if it really offends your eyes you could try something like: print "foo" and $count = 0 if ( cond ) or something similar. Of course, that won't set $count to 0 if the print fails, which might be a feature.

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).
