Save integer variable

Hi all,

I'm a beginning level programmer (hobbist) and I would appreciate if someone could give me a clue on a method to save a value from a variable. I would like to update the value during program run time and then on the next time usage of the program have an updated value to use and update again.

Write the variable to a file. Read the variable back from the file next time you run the program.

And it would be more portable and readable to write it out in a text representation.

Thanks guys for the direction on this question, I looked it up in a couple of resources and it looks like that should help with the code. So for now read, write and test what I've got, and again thanks for the swift response.
