For the demo I'm working on, I have a LOADER.PRG in the AUTO folder, which then loads the actual DEMO.PRG with a standard PEXEC.
However, since I want people to be able to run it from harddisk too, I want the user to be able to start it from DEMO.PRG aswell.
The problem is that when DEMO.PRG exits (when it's been PEXEC:ed from LOADER.PRG), the computer crashes, and I suspect the reason is that LOADER.PRG runs in supervisor mode, as does DEMO.PRG. I'm thinking a solution would be if DEMO.PRG detects if the Atari is already in supervisor mode, and if so, simply runs without setting supervisor mode itself.
But how do I detect if I'm in supervisor mode? Or is there a better way to solve this problem?
The reason LOADER.PRG is in supervisor mode, by the way, is that it places a tiny animation on $70, and that animation needs to be in supervisor mode.
Thanks in advance,
Per.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
