--** copy and go code ;)
--** some simple code to add or subtract apples..using a function ;)
_G.totalApples = 16; --Global depending program needs and scope
--** local totalApples = 16; --**Or could be local like this
 
 
local function addMoreApples(howManyFound)
 
        --** you could add / subtract / ...etc
        totalApples = (totalApples + howManyFound);
        
        --** then return to calling function
        return totalApples;
        
end
 
local function main()
 
        local applesReturned = 0;
 
        print("\nTotal apples when we started:  ", totalApples);
        
        --** we found some more apples under the tree..;)
        applesReturned = addMoreApples(14);
        
        
        print("\nThis Way also!  ", applesReturned);
        
        
        print("\nTotal apples this way too!", addMoreApples(14));
        
        
        print("\nTotal apples when we ended:  ", totalApples);
 
        
        --** main()'s return to system
        return 0;
        
        --** anyway there's alot of different ways to do what
        --** you need / want
        --** just stay with-in the .lua/corona programming lanq. ;)
 
end
 
--** run our main() 
main();
