undef AoHoA

[CJason]

How do you "undefine" an Array of Hashes of Arrays? It must not be as simple as:

undef @AoHoA;

because, I can't seem to get that do work?

I have @AoHoA that is filled. I want to clear that structure out completely...so that the test (for example):

if (defined($AoHoA[0]))

fails. That is, it's NOT defined (but, it was before I "undef" it).

Thanks in advance!

It turns out this is something a little more complex. I'm sending this AoHoA to a subroutine in a .pm file. It seems that once the AoHoA is set in the .pm, it doesn't ever get undef'ed...even when I undef the AoHoA being passed into the subroutine? Any ideas? If this isn't clear, please let me know and I'll try to explain better...

You are likely not [tt]use[/tt]ing [tt]strict[/tt] (as I do most of the time ): when you pass the array to the subroutine it comes back into existence. Anyway those behaviors are quite difficult to interpret them fully.
For your problem just do
[tt]@AoHoA=();[/tt]
and the full structure will be cleared.
