in reply to Does undef free ram?

Just to echo what bronto already said -- let the arrays you don't need go out of scope and let Perl take care of the memory management. That's cleaner than using undef on the arrays.

    Except this isn't entirely true--perl doesn't release the memory used for the array itself, though the memory for the scalars is released. If you want an array's memory released, you do have to undef it.
