exit revolution with 0 or 1

[Thierry]

Hi,

launching Revolution from a shell,
I'm doing some checking inside a stack.

Then, i would like to quit Revolution so the shell ( the caller )
could catch an exit 0 if OK or an exit 1 if Error.

Don't see anything except the quit command.

Found a workaround in within the shell, but
not happy with this.

Any hint or ideas ?

Regards,
Thierry
