Dark Basic Lite is Dark Basic Classic, only without EXE saving capabilities to make it more budget priced for the starter. You can still execute the stuff you make with it and save the source, so I wouldn't upgrade if I were you, if you only need it for that tut and you already have DBP.
Besides, i think if you put DBC code in DBP it works, but not the other way around...maybe I'm wrong.
