limitless arrays

Hi I hope this doesnt sound too weird:
I'm making an editor program for custom data that has to be read at runtime afterwards - I wonder if there is any way to have limitless arrays?

I've seen that there's a default X, Z and Y dimension that needs to be set at first, then at runtime the addresses of each data is set within those boundaries, but is there any array object without any boundaries wich could just store and save what has been written/stored ?

thank you

Those settings are only the initial dimensions - even the standard array object will resize dynamically, so it doesn't have boundaries.

this is awesome.

thank you
