Saving multiple arrays with applicationStorageDirectory

Im having trouble even finding a simple example I can work with.

I want to save multiple arrays with applicationStorageDirectory. Im using Flash Pro and it's air for ios. How would I go about writing data and then reading from the arrays?

Example array would be like this:

var exampleArray:Array = [ArrayOne,ArrayTwo,ArrayThree];

I have this working with LSO on the computer, but on mobile it doesnt work-im guessing the size limit is too much (64 arrays with 190 entries on each) so I want to use applicationStorageDirectory.

Id appreciate the help. Thanks.
