Hello,

I was trying to assing a value to $hash{'AirIATA'} but was failing and then used @hash{'AirIATA'} and voila, it worked but I got a warning as "Scalar value @hash{'AirIATA'} better written as $hash{'AirIATA'} at makeAnnounce.pl line 31."

So, what is wrong or what is right ?

Here is the problematic part of my code;

file1; 
@hash{'AirIATA'}=get_IATA($airlineLoc,$hash{'Airline'});

my $letter1 = substr($hash{'AirIATA'},0,1);
my $letter2 = substr($hash{'AirIATA'},1,2);

print $letter1,"\n",$letter2,"\n";

------------

file2; 
sub get_IATA
{
        my $file = shift;
        my $airline = shift;
        my @data;
        my $count=0;

        open(my $fh, '<', $file) or die "Can't read file '$file' [$!]\
+n";

        while (my $line = <$fh>)
        {
                my @fields = split(/;/, $line);
                push @data, @fields;
        }
        foreach my $data ( @data)
        {
                if ($data eq $airline)
                {
                        return $data[$count-1],"\n";
                }
                $count++;
        }
}
