[A83] Re: Do I get this?
Well I was actually too lazy to try :-)

Yes, It works.(83+) 22272=$5700
Hey! TI changes the stack pointer right after that
5700:call $254E
245E:pop bc
254F: ld sp,($86DE)
If you set a breakpoint at $5700, it monitors exactly when an asm-program
stops (not an ion program). During a quick test, I didn't find any other
calls of $5700. Could be useful, probably.
