How can you implement data persistence when using Action script 3.0?

Question

ActionScript

Let's say there is some application with an empty text field in the center. I'll put my name in it: "intTosha". When you close and then open the program, you will have to enter your name there again ... And then I begin to think about the need to allow the application to remember the entered data. But I don't know how...
How to implement it?...
Of course, the application is imaginary and hardly anyone will need it, but it is simple enough for a good example for young minds.
I will accept any pieces of code, at least somehow related to this issue.
Thanks to all.

Answer 1

If under flash player, SharedObject, if under AIR - you can save any files in any form via File/FileStream or sqlite database.

Answer 2

Loop
- Changed links counter = 0
- Loop over all vertices
- - If a link enters a vertex and a link goes out (it owes it and owes it at the same time), then replace it with two (or one) direct links, breaking the chain and increasing the counter of changed links .
Loop exit if changed links count = 0
