G'day juanito23,

What you show at the start is invalid syntax. If that's returned from Text::CSV's getline() method, you have an arrayref (["m2000_id", ...]). If it's really an array, it looks like ("m2000_id", ...). Furthermore, as you've said "already done", this would seem to suggest that this is partially processed data: perhaps you started with string of comma-separated values. Not knowing the data you're working with is not a good start.

Your other code fragment is incomplete. Where's the if block? What value does $_ hold? How does it get that value? (By the way, 0 .. 10 is a range of 11 values!)

Here's how I might have iterated over an array testing both element content and array index: 

#!/usr/bin/env perl -l

use strict;
use warnings;

my @array = qw{! 1 A @ 2 b $ 3 c % 4 D ^ 5 e};

for my $i (0 .. $#array) {
    if ($array[$i] =~ /[a-zA-Z]/ || $i < 10) {
        print "[$i] Quote: '$array[$i]'";
    }
    else {
        print "[$i] Don't quote: '$array[$i]'";
    }
}

Output:

[0] Quote: '!'
[1] Quote: '1'
[2] Quote: 'A'
[3] Quote: '@'
[4] Quote: '2'
[5] Quote: 'b'
[6] Quote: '$'
[7] Quote: '3'
[8] Quote: 'c'
[9] Quote: '%'
[10] Don't quote: '4'
[11] Quote: 'D'
[12] Don't quote: '^'
[13] Don't quote: '5'
[14] Quote: 'e'

That might at least give you a starting point.
