[Buffalo-pm] Question: How to iterate through 2 arrays andmerge columns

[Shaun Griffith]

You may want something like this:

    foreach my $i ($i=0;$i<@red;$i+=4)
    {
        printf "%s\t" x 8 . "\n", @red[$i..$i+3], at green[$i..$i+3];
    }

This assumes that you have checked that @red and @green are the same length,
and multiples of 4. (Use whatever is appropriate for the "%s" descriptor.)
