Simple data persistence.

A simple api for making persistent variables. You can use store(name, value) to save a variable and pull(name) to get the value of a previously stored one. Using store(name, nil) or just store(name) (since no input defaults value to nil) will delete the variable.

Can someone reply please?

Simple and was made many times.
But should work (not tested).

maybe take a look at my code?
have improved so you don't need to type your variable name EVERY time you want to save something
also it's a bit more OOP :)/>/>
(haven't tested it yet so hope it doesn't contain some bugs)
