in reply to parsing lists

1) put

use warnings; use strict;
at the top of your file.

2) I think you are missing a semicolon at the end of -the "open" line.

UPDATE: Here's some untested code...

use warnings; use strict; $count = 0; open (DISTLISTS, " < rdy.csv") || die "Unable host file for splitting: + $!."; while (<DISTLISTS>) { chomp $dist_split; if ($. % 200 == 0) { # modular arithmetic $count ++; } my $filename = "file$count.csv"; open (OUTPUT1, " >>$filename") print OUTPUT1 "$dist_split\n"; close OUTPUT1; }

    put the open inside the if block and the close outside the while block.

      Yep. Ok this is tested and works.
      use warnings; use strict; my $count = 0; my $filename = "file0.csv"; open (DISTLISTS, " < rdy.csv") || die "Unable host file for splitting: + $!."; while (<DISTLISTS>) { chomp $_; if ( ($. - 1) % 200 == 0) { # modular arithmetic $count ++; my $filename = "file$count.csv"; open (OUTPUT1, " >$filename") } print OUTPUT1 "$_\n"; if ($. % 200 == 0) { # modular arithmetic close OUTPUT1; } }
