Hello Perl Monks,

What am i trying to do is extract data from directory of CSV files, in which columns are separated with ";"

eg.Table;M
     Data;O
     ......

The ouput file must be made as this structure:

%hMFD = (
         Name_of_the_file_without_ext => {
                 Fieldname_1(column A) => 'value M or O(column B)',
                 Fieldname_2(column A) => 'value M or O(column B)',
    .
    .
    .
                 Fieldname_x(column A) => 'value M or O(column B)',
                },
         Name_of_the_next_file_without_ext => {
                 Fieldname_1(column A) => 'value M or O(column B)',
                 Fieldname_2(column A) => 'value M or O(column B)',
    .
    .
    .
                 Fieldname_x(column A) => 'value M or O(column B)',
                },
     );

here what i did:

#!c:\perl\ -w
use Text::CSV;
opendir(KAT, "$ARGV[0]"); 
@fls=grep {/\.csv$/} readdir KAT;
closedir KAT;
foreach $fl(@fls) {
    $fl=~s/\..*//;
    print "$fl\n";
    }    
@files=<C:\\experl\\csv\\*.csv>;
    foreach $file (@files){
        print "$file\n";
        }
foreach $file (@files){
        my $csv = Text::CSV->new();
        open (CSV, "<", $file) or die $!;
            while (<CSV>) {
            if ($csv->parse($_)) {
            my @columns = $csv->fields();
            print "@columns\n";
            } else {
            my $err = $csv->error_input;
            print "Failed to parse line: $err";
            }
            }
        close CSV;
        }

still it is only making list of files as an array, and reads all data without separating them, i have no clue how to combine this into hash of hashes, i would be grateful for some advice, this task is to hard for me at this point
