A couple of fixes and a couple of suggestions. First, the mkdir thing has a precedence problem, as tye suggests. Use parenthesis or or to fix it:
mkdir("$dir", 0777) || die "Could not mkdir \"$dir\": $!\n";
Second, the chop bothers me, 'cuz it's easy to grab something you don't want. (In this case, it's right, but I prefer chomp).

Third, there are a couple of other ways for doing your menu stuff. Some people prefer this:

($menu eq 1) && addwant(); ($menu eq 2) && addhave();
When I have to do something like this, I usually use a data structure of references:
my @actions = qw( \&addwant \&addhave ); # and so forth # get input if (defined (my $action = $actions[$menu])) { $action->(); } else { print "\n\n\nGoodbye!\n"; exit; }
Finally, if you want to clear the screen, there's a bit in perlfaq8 that might help. Not a big deal, though.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
