Can anyone shed array of hope?

[Marukamu]

Bad pun, yes, I know, but that's not the point.

I've used arrays before in other programming languages, and the array seems to differ between languages. What I want to know is how arrays are used in Graal ( the command panel is not much help... ), and are they saved in any way like flags are?

What I am trying to do is use an NPCW to store certain settings in an array, and when necesary, display them in a GUI, and the data I want to store may not always be the same.
