I think you need a C-style for loop, to keep track of the array index. Something like this:

for my $i (0 .. $#cg)
{
    my $g = $cg[$i];

    if ($g eq $gl[$i])
    {
        push @ind, $g;
        print N "$g\n";
        print S "$csta[$i]\n";
    }
}

Is that what you’re looking for? If not, please specify sample input (the contents of the arrays) together with the output you expect.

Hope that helps,
