# set

```lua
 function test() 
    wait(3);
    
    local myValue = get('testValue'); --gets the global object/variable testValue from the main script
    
    log(myValue); --prints 10

    myValue = myValue + 15; --adds 15 to the local variable
    
    set('testValue', myValue) --sets the main script variable to the local variable here. **25**
end
return function()

    testValue = 10;
    
    local coroutineId = async('test');
    
    waitForCoroutine(coroutineId);
    --while waiting the async coroutine is playing it will print
    --10
    
    log(testValue); --prints 25
    log('finished');
end
