Need Help??

Your slurp:

    @files = { local(@ARGV, $/) = @filenames; <> }; # missing 'do'
[download]

Should actually be:

    @files = do { local(@ARGV, $/) = @filenames; <> };
[download]

And your index hash:

    @foo{ @foo } = 0 .. @foo; # off-by-one error
[download]

Should be:

    @foo{ @foo } = 0 .. $#foo;
[download]

You are right about the slurp, a typo on my part. But the indexing will work. The extra number (int @foo) will just be ignored because there won't be a corresponding lvalue. Ted :->	[reply]
