Re: Appending new column data to CSV file?

[Cristoforo]

In the while loop, these 2 statements:

        $sum += $col5;
        push @numbers, $col5;

$sum and @numbers need to be declared before the while loop that reads the file. Then after each file is read, statements:

    while (my ($i, $num) = each @numbers) {
        push @{ $output[$i] }, $num/$sum;
    }

You would need to declare @output before the foreach loop begins.

Then after all the files have been read and the info collected, you could print it out like: print OUT join(",", @$_), "\n" for @output;
