So I'm basically writing this script where you can create an "account", which should act as a kind of a debit card.



I'm generating a random number and storing it in a file for the "account number", but I don't know what to do after this. I want the account number to be linked to a value (the money it contains), so that later when I add money in the script, it changes in the file.
