1) Think why If index >3 didnt work earlier.

2)

Learn C.

You can handle a string as an array, and FOR through it.

Sub and Function are similar, functions return a value, Subs dont.

So you could set

a = function(b)

but not

a = sub(b)

I have no idea on the end thing. I guess that end is equivalent to a C++ destructor, which cleans up the object then deletes it so you dont have any dead ends, whereas unload me would be equivalent to the free() function. End sounds safer. But Im guessing here.
