in reply to the repetition operator does not repeat "\x00" Why?

The repetition operator works fine, try print length $_; it's Data::Dumper that does not output the '\x00' ...

    Data::Dumper prints it for me (Perl 5.8.8, Solaris): 
    perl -MData::Dumper -e '$_ = "\x00" x 4; print Dumper $_' | cat -v
$VAR1 = '^@^@^@^@';

      You are correct, Data::Dumper prints the '\0' but it is only visible in the output via something like cat -v. Nice trick btw, I didn't know about that. Thank you!
