in reply to text formatting in columns with hash?

This works if you have an even number of lines after the header, as your output does (your input has an odd number for some reason):
use warnings; use strict; my @lines = <DATA>; chomp @lines; my $head = shift @lines; print "$head $head\n"; my $count = @lines / 2; for my $i (0 .. $count-1) { print "$lines[$i] $lines[$i+$count]\n"; } __DATA__ a b c 0 0 d 0 1 d 0 1 d 0 2 d 0 2 d 1 0 d 1 0 d 1 1 d 1 2 d 1 2 d

    The requirements seem a bit more complicated. In the output, only the 'a' value is different between the two columns. The string which does not fit that pattern is skipped.
    UPDATE: My description of the output is wrong! I cannot figure out t +he real requirement.
