How to store multiple variables in a .DAT file?

I need help creating save data for a game I'm making and it needs to store multiple variables. I haven't programmed in a while so I'm a little rusty.

You can use something called an array. It's basically a list of variables. You can store numbers in an array with something like:

MAXIMUM=3 'maximum number of variables
DIM ARRAY[MAXIMUM]
ARRAY[0]=1
ARRAY[1]=6
ARRAY[2]=4

Then all you need to do is save the array in a DAT file.

SAVE "DAT:NAME",ARRAY

How would I call the numbers from an array in to variables? EDIT: Would it be something like:

VARIABLE=ARRAY[9]
