We can avoid pushing into an array @file if the goal is just to print it out:
while(<DATA>)
{
chomp;
# find out if there's a line continuation
# and remove the trailing backslash
my $cont = s/\\\s*$//;
# print without newline, no matter what
print;
# decide whether to end print with newline
print "\n" unless $cont;
}
Update: Actually, a simple substitution would suffice:
while (<DATA>)
{
s/\\\s*\n//;
print;
}

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).
