in reply to Double blank lines to single blank line

What does your input code look like currently? The appropriate solution depends a lot on how you are doing stuff now and to some extent on what gets done with the data subsequently.

    A bit too deep into data massaging on this set of data to go back to original code. Good point though. I think I can fix the original code but I need to know what to do to work with the existing set with the double blank lines. There must be a script or a way to do this in word etc quickly.

      Something like:

      use strict;
use warnings;

my $run = 1;

while (<DATA>) {
    next if $run && m/^\n/;
    print;
    $run = m/^\n/;
}

__DATA__
data as per sample

      with i/o adjusted for your requirements should do what you need to clean up multiple line breaks.
