Re^6: Do I need to use defined?

...

Read my posting again. I'm using list context in both cases.

Or just read "Truth and Falsehood" in perlsyn:

The number 0, the strings '0' and "" , the empty list () , and undef are all false in a boolean context. All other values are true. Negation of a true value by ! or not returns a special false value. When evaluated as a string it is treated as "" , but as a number, it is treated as 0. Most Perl operators that return true or false behave this way.

I'm using list context in both cases. No you're not. `or` puts its left-hand argument in scalar context.	[reply]
