My guess is that line 52 corresponds to

foreach my $m(0..$#row1)

If not, you should indicate since you haven't given us 52 lines of code. In the above, $#row1 is the last index of @row1, which you don't define. Since you want the last index of the array referenced by $row1, you mean

foreach my $m(0..$#$row1)

Note the extra sigil (and see perlref and/or perlreftut). A less error prone way of writing that block assuming you don't need the index would be using a foreach loop on the array itself: 

foreach my $record (@$row1)
    {
        
        $data_file.= $record->{'ROW_DATA'} . "\n";
        
    }

Update: You are also accessing the array reference improperly in the line

$data_file.= "$row1[$m]{'ROW_DATA'}\n";

which should be

$data_file.= "$row1->[$m]{'ROW_DATA'}\n";

since you need to dereference that reference to access its contents. You should probably (re)read perlreftut to gain insight into how references work in Perl.
