Hello monks,

I am confronted with an error here I am not understanding for I have done this many time and this time it does not seem to work.
I looked at earlier code I made in Perl and it is pretty much done in a similar manner.
Any clues on why I have this error: readline() on close filehandle $handle?

Thanks

sub changeData{
        my ($self) = @_;

        `$toolPath/an2k2txt ./Templates/DFP.nst ./tmp/Data2`;

        open my $handle, "<", "./Data2";

        my $file = new IO::File("./$self->{_nistName}.tmp","w");

        my $data;

        while(<$handle>){
                if ($_ =~ m/$self->{_field}/i){
                        chomp($_);
                        $_ =~ s/=.*//;
                        #Seems that \x1F\x0A is the delimiter at the e
+nd of the lines
                        $data = $_."=".$self->{_newValue}."\x1F\x0A";
                        print $file $data;
                }
                else{
                        print $file $_;
                }
                print "$_\n";
        }
        close $handle;
        `$toolPath/txt2an2k ./$self->{_nistName}.tmp ./Nist/$self->{_n
+istName}.bad`;

        system("rm -f ./*.tmp");
