I am trying to open a file for reading and writing. i open the csv file for read/write '+<', then read it line by line, and if the first column is not empty, then it should print out to the same file, but it displays 'can not close file', if i change the '+<' to '+>' i just get a blank file 



 open my $data, '+<', $INFILE1 or die "can't open\n$INFILE1\n";
    while (<$data>) {
    chomp;
    my ( $data ) = split (',',) ;
    if ($data ne ""){
    
    print "$_ \n";
next;
   }
   close $data or die "can't close\n$INFILE1\n"; 
}
