Hi all
I'm reading in a file. Each line consists of some data, and if the line is longer that 80 chars it continues onto the next line but appends a + to that line. 
foo bar foo bar foo bar...bar
+foo bar

I want to reconstruct this line into a single line so I can work with it later. Here is what I came up with, but it doesn't work nicely.. Can anyone help me out..
#each element in the array is a single line
  my @netlist = <NETLIST>;
  close(NETLIST);

#while it is not the end of the file
  while($line = shift @netlist){ 
    chomp $line;
    my $tmp = $line;
    $line = shift @netlist; chomp $line;
    if ($line =~ /^\+/){
      # Is this a continuation..
      s/^\+//;      #remove the continuation
      $tmp = $tmp . $line;
      print "$tmp \n";
    }else{
      pop (@netlist, $line);
      print "$tmp";
    }
}

Thanks much. If there is a simpler more <it>perlish</it> way to do this I am really open to suggestions. Additionally as some point I am going to need to reconstruct this long line so it doesn't go over 80 chars, and doesn't break up words. I am really open to suggestions here.. Thanks so much!!
