I have csv file and i want to modify some field's value. I tried by creating new csv with modified value and then renamed with original one but i want to open that file in read/write mode and do simultaneously(no rename). Here is what i tried but not successful. Thanks in advance.

sub modifying_csv
{
    my $file=shift;
    open FH,"+<$file";
    while(<FH>)
    {
        my $line= $_;
        if($line =~ /43950635/)
        {
            $line =~ s/(.*)(43950635)(.*)/"$1$2BIM$3"/;
            $line =~ s/\"//g;
            #print  "$line";
            print FH "$line";
        }
    }
    close FH;
