Re^2: Argument "" Isn't numeric in numeric eq (==)

This looks really cool. But how did you manage it before?

Imho it looks like CSV and the OP needs to do something like my @f = split ',', $data;.

This yields:



$VAR1 = [
          '1',
          '1'
        ];
[download]

And after casting it:

$VAR1 = [
          1,
          1
        ];
[download]

What do i miss (or perhaps yet another mental block)?

Best regards, Karl

I do not understand the question. I just populated the @f array as in the OP. I just used `while (<DATA>) { my @f = (undef, split /,/);` [download] as the @f in the OP is not zero based, but one based. There is no need to cast between strings and numbers in Perl. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l]

"There is no need to cast..." Yes s(h)ure. I was a bit confused about this Isn't numeric in numeric eq (==). Sorry, i couldn't explain it better :-( Best regards, Karl «The Crux of the Biscuit is the Apostrophe»	[reply]

The empty strings were the reason of the warning. They are handled by the `\|\| 0`, because emtpy string is false. لսႽ† ᥲᥒ⚪⟊Ⴙᘓᖇ Ꮅᘓᖇ⎱ Ⴙᥲ𝇋ƙᘓᖇ	[reply] [d/l]
