I use ProSEL, but they all follow the same technique AFAIK. I assume
it's a simple matter of rescanning the input buffer at launch.
BASIC.SYSTEM uses this technique to allow launching BAS and BIN files
from a selector...

I see what you mean with the quit code... Perhaps you could copy it to
the heap area and trash it only when memory becomes tight? As for 128k
systems, that's nice and easy. As long as /RAM is connected when your
SYS program starts, you can disconnect it then reclaim the entire aux
bank for your own purposes. It's only when /RAM is disconnected at
launch that the Aux LC reserved area must be respected.
