I have a question about the following : 
use Data::Dumper;
# it seems that ', ,' in the third record is not producing a index in 
+the array.   
$arr= [
    [1,2,3,4,5,6,7,8,9 ],   #works as expected
    [1,2,3,'',5,6,7,'',9 ], #works as expected
    [1,2,3, ,5,6,7, ,9 ],   #does not work as expected "empty fields "
+ are ignored
];


my $dd=Data::Dumper->new([$arr],[ qw(arr) ] )->Indent(1)->Quotekeys(0)
+->Dump;
print $dd;

$str_arr=q`$arr= [
    [1,2,3,4,5,6,7,8,9 ],
    [1,2,3,'',5,6,7,'',9 ],
    [1,2,3, ,5,6,7, ,9 ],
];` ;
print "\n\n";
print $str_arr ;

$str_arr=~ s/,\s*,/,'',/g; # filling in the empty fields
print $str_arr ;
$arr = undef;
$arr = eval $str_arr;

my $dd=Data::Dumper->new([$arr],[ qw(arr) ] )->Indent(1)->Quotekeys(0)
+->Dump;
print $dd;

# this seems to work, next question is : The original $arr is send to 
+a subroutine. 
# How to stringify that in the subroutine without hardcoding this. ( a
+s I have done in the above ) !
