No sane Basic should leak stack memory just because you exited an "If-Then" block without reaching the corresponding "End". Yes that's a thing. If you use "If-Then" and the code never reaches the "End" because you used "Goto" to leave the block, a few bytes are leaked every time that happens, and eventually the program stops with "ERR: Memory". You needed to use "If" then "Goto" on the immediate next line, and that would avoid the leak. Exiting the program or stopping it will give you back all the leaked memory, including seeing that error.
Then you have the lack of actual subroutines or functions. All you can do is call into a separate program, and return things by putting them in specific variables. But the Basic doesn't even have "Gosub".
Also, it's very very slow.
