Erm, split?

Here's a split example:

my( @match_A ) = split /\t/, $line;

Just a matter of using the right tool for the job.

Then you could verify if there are enough items on array:

if ($#mach_A < 41) {
    # Less columns than expected. 
    warn "Line has less columns than expected.";
}

Hi Win,

What you need is split function.
