ActionScript 3.0 :: Save And Retrieve Input Text Data?

I would like to know if it is possible to save data from an input text field to a file on my computer, then retrive the data from that file and load it into a dynamic text field. This application is not and will not be on a website of anysort its an experiment in creating a sorta phone book on my computer. I have created 2 input text fields. the first one is where i would enter a persons name, instance name of "_name", the second input text field is where i would enter a phone number, instnace name of "_phone".

Also there is a button with an instance name of "_save", which hopefully will save the data to a txt file on my computer or something, at this point i am up for anything. what I dream of doing is haveing two projectors one for entering the data, and the other for retrieving the data. The second projector, i would like to beable to type in a name or phone number then it would display, load, retrieve the name and phone number from that file storing the data.
