Re^5: if (defined @arr) problem

[secret]

remove all of the elements of the array

Well that would be @array = ()

replace all of the elements with the value undef

That could be @a = (undef) x scalar @a

So yes , saying "undef an array" i meant  undef @a . I do think it's what the OP was meaning to do when trying to affect one single undef value to the whole array . This really sounds like undef @array.

Now about delete for the moment i never got to use it, neither did i use exist . I gather it's because they are used mainly with objects, are they ?
