You could do something like this:
#!/usr/bin/perl -w
use strict;
my @fh;
# open all files
for my $i (0..$#ARGV) {
open $fh[$i], "<", $ARGV[$i] or die $!;
}
while (1) {
my @lines;
# read one line from each file
push @lines, scalar readline $fh[$_] for 0..$#ARGV;
last unless defined $lines[0];
chomp @lines;
print join(",", @lines), "\n";
}
$ ./950649.pl infile1 infile2 infile3 ... > outfile
(Note that you have to use readline with "complex" file handle expressions like $fh[$i], as <$fh[$i]> wouldn't work here.)

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).
