Wow this is so cool! Thanks Boris/C/Mirod!

I intially thought I will just learn how to open multiple filehandles but got lured into implementing the paste command like program (not there yet :)).. Here is my code but for some reason my  $line variable does not get set to undef when 'all' filehandles runs out of data...Should i be checking for something else to terminate the loop?

I guess the code will be much faster if i can generate perl code that puts all the filehandles into one line without looping them through it... 

#! /usr/local/bin/perl -w

# Open many file handels

# C's code
foreach my $file (@ARGV) {
   my $fh;
   open $fh, "<", $file or die "Can't open $file ($!)";
   push @filehandles,  $fh;
}

while (1) {
    $line = undef; # Not sure whether this is even required.
    foreach (@filehandles) {
        $line .= <$_>;
        chomp($line);
    }
    print ($line,"\n");
    last if undef($line);
}
