How does war3 allocate memory

How does warcraft 3 allocate memory when you have an array, that has a defined size and also an undefined size. I heard someone mention that memory is allocated in powers of 2, ex if you use index of 300 in an array, there would be 4*512 bytes allocated, so memory of 0-511 indexes would be used, even if you don't actually set values to them, or was the person wrong? If he was, please explain exactly how it's done.

That is correct. I reversed that stuff pretty thoroughly, though it's been a couple years. There are Cheat("") commands in war3err to print the array size you can use to investigate yourself.
