Subject: | Argument "" isn't numeric |
Running my code which complies with the module's API documentation, I
get the fatal error:
Argument "" isn't numeric in numeric ne (!=) at
/usr/lib/perl5/site_perl/5.8.8/File/DirWalk.pm line 120.
My code can be seen at: http://pastebin.com/hJu7vkXq. I'm trying to
create a directory tree with indentation using the module and am using
Perl 5.8.8.
