Is there a version of QBasic between the one that comes with the old DOS and QB4.5? Because I have QBasic programs that won't run in the old QBasic because "Advanced feature unavailable" and QB4.5 doesn't like a CALL statement it made. Also, is there somewhere that lists the peek and poke addresses for QBasic? Or are the memory address universal? Because I know that QBasic handles memory allocation differently than other programming languages.
