How do I return a return-code from main?

[wl]

Hi all,
Pls help with the following:

I have a stand-alone java program which will need to return a return-code to
the running script. I thought I could just use:

return -1;

inside the "public static int main(String[] args)". However, I get an
error. Apparently, I can only have "public static void main(String[]
args)".

Is there a way I can return a return-code?

Thanks,
Bill

Try System.exit(-1)

In case you're wondering, it's JVM, not main() that returns to OS.
main() returns to JVM (which may or may not terminate then).
