It's a nonsense question. * I think this is a little to easy, perl does have a value that indicates that a variable does not have any set value it is called: undef In many other langueages like Java, Visual basic, C++, SQL, I thought even in Pascal a value of NULL signifies that the variable does not have a set value, it is not defined. Exactly what a value of 'undef' signifies in perl.
Pigs do not fly that much is true even if you manage to throw them real high they will not fly but just crash right back to earth, but perl does have a way to indicate that a variable has no value set. I thik the thing that Randal was saying is that 'NULL' does not exist as a value in perl but he left out the part that others have pointed out before 'undef' has the same significance in perl as 'NULL' in other languages.
