MultiDimensional Arrays

[DarkShadows_Legend]

This is new to me and it looks weird. Will someone be kind enough to explain to me how they work and provide some basic examples. I just got GS2 on this world I'm developing and want to experiment with this stuff.

I have seen some scripts that have lines of code like ...

NPC Code:

---

myvar = {{{val}}, val2, val3};

---

I believe there is another way of creating them for GS2 that is like old GS1

GS1 -> setarray myvar,length;
GS2 -> setarray(myvar,length); // not quite sure

How would a multidimensional array be set for GS2?

If anyone could explain this to me and provide a couple of examples I would be extremely greatful. Thanks
