when you change the code to print out the values of $name, $1, and $2:
foreach $name (keys %book) { #write the data print "$name \n"; $name =~ /(.+)&(.+)/; print "$1, $2 \n"; if ($2 =~ /^0$/) { print BOOK "$1,::"; } else { print BOOK"$1,$2::"; } for ( 0 .. $#{ $book{$name} } ) { print BOOK $def[$_+2] . ":" . $book{$name}[$_] . "::" unless +$book{$name}[$_] =~ /^0$/; } print BOOK "\n"; }
you get the correct output, and it shows $1 and $2 are initialized, but you still get the uninitialized error. Here is the output when you pass it School&0 and one number:

school&0

school, 0 
# Use of uninitialized value, <> chunk 7.
File 'untitled:Desktop Folder:Will's Stuff:Applications:MacPerl :phonebook'; Line 57
so that isnt the problem. Loop lables are a good idea, though, thanks

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.
