Re: How to get 0 to initialize a value

When I run your code I do not get the warnings you mention, but this line:

my $first_novel = $novel_list->[$first_book];

does give a ~~warning~~ fatal error (praise be to monk of anomaly). @novel_list is a plain array not an array reference - it should be:

my $first_novel = $novel_list[$first_book];
[download]

You may say this is a trivial difference, but a warning is not fatal — unless you explicitly make it so! Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]
